Lemon also uses a parsing engine that is faster than yacc and bison and which is both reentrant and threadsafe. (Update: Since the previous sentence was written, bison has also been updated so that it too can generate a reentrant and threadsafe parser.) Lemon also implements features that can be used to eliminate resource leaks, making it suitable for use in long-running programs such as graphical user interfaces or embedded controllers.</p> <p>This document is an introduction to the Lemon parser generator.</p> <h2>Security Note</h2> |

This is accomplished by calling the following function once for each token: <pre> Parse(pParser, hTokenID, sTokenData, pArg); </pre> The first argument to the Parse() routine is the pointer returned by ParseAlloc(). The second argument is a small positive integer that tells the parser the type of the next token in the data stream. There is one token type for each terminal symbol in the grammar. The gram.h file generated by Lemon contains #define statements that map symbolic terminal symbol names into appropriate integer values. A value of 0 for the second argument is a special flag to the parser to indicate that the end of input has been reached. The third argument is the value of the given token. By default, the type of the third argument is "void*", but the grammar will usually redefine this type to be some kind of structure. Typically the second argument will be a broad category of tokens such as "identifier" or "number" and the third argument will be the name of the identifier or the value of the number.</p> <p>The Parse() function may have either three or four arguments, depending on the grammar. If the grammar specification file requests it (via the <tt><a href='#extraarg'>%extra_argument</a></tt> directive), the Parse() function will have a fourth parameter that can be of any type chosen by the programmer. The parser doesn't do anything with this argument except to pass it through to action routines. This is a convenient mechanism for passing state information down to the action routines without having to use global variables.</p> <p>A typical use of a Lemon parser might look something like the following: <pre> 1 ParseTree *ParseFile(const char *zFilename){ 2 Tokenizer *pTokenizer; 3 void *pParser; 4 Token sToken; 5 int hTokenId; 6 ParserState sState; 7 8 pTokenizer = TokenizerCreate(zFilename); 9 pParser = ParseAlloc( malloc ); 10 InitParserState(&sState); 11 while( GetNextToken(pTokenizer, &hTokenId, &sToken) ){ 12 Parse(pParser, hTokenId, sToken, &sState); 13 } 14 Parse(pParser, 0, sToken, &sState); 15 ParseFree(pParser, free ); 16 TokenizerFree(pTokenizer); 17 return sState.treeRoot; 18 } </pre> This example shows a user-written routine that parses a file of text and returns a pointer to the parse tree. (All error-handling code is omitted from this example to keep it simple.) We assume the existence of some kind of tokenizer which is created using TokenizerCreate() on line 8 and deleted by TokenizerFree() on line 16. The GetNextToken() function on line 11 retrieves the next token from the input file and puts its type in the integer variable hTokenId. The sToken variable is assumed to be some kind of structure that contains details about each token, such as its complete text, what line it occurs on, etc.</p> <p>This example also assumes the existence of structure of type ParserState that holds state information about a particular parse. An instance of such a structure is created on line 6 and initialized on line 10. A pointer to this structure is passed into the Parse() routine as the optional 4th argument. The action routine specified by the grammar for the parser can use the ParserState structure to hold whatever information is useful and appropriate. In the example, we note that the treeRoot field of the ParserState structure is left pointing to the root of the parse tree.</p> <p>The core of this example as it relates to Lemon is as follows: <pre> ParseFile(){ pParser = ParseAlloc( malloc ); while( GetNextToken(pTokenizer,&hTokenId, &sToken) ){ Parse(pParser, hTokenId, sToken); } Parse(pParser, 0, sToken); ParseFree(pParser, free ); } </pre> Basically, what a program has to do to use a Lemon-generated parser |

But the input file also specifies additional information Lemon requires to do its job. Most of the work in using Lemon is in writing an appropriate grammar file.</p> <p>The grammar file for Lemon is, for the most part, free format. It does not have sections or divisions like yacc or bison. Any declaration can occur at any point in the file. Lemon ignores whitespace (except where it is needed to separate tokens), and it honors the same commenting conventions as C and C++.</p> <h3>Terminals and Nonterminals</h3> <p>A terminal symbol (token) is any string of alphanumeric and/or underscore characters that begins with an uppercase letter. A terminal can contain lowercase letters after the first character, but the usual convention is to make terminals all uppercase. A nonterminal, on the other hand, is any string of alphanumeric and underscore characters than begins with a lowercase letter. Again, the usual convention is to make nonterminals use all lowercase letters.</p> <p>In Lemon, terminal and nonterminal symbols do not need to be declared or identified in a separate section of the grammar file. Lemon is able to generate a list of all terminals and nonterminals by examining the grammar rules, and it can always distinguish a terminal from a nonterminal by checking the case of the first character of the name.</p> <p>Yacc and bison allow terminal symbols to have either alphanumeric |

We've described all the grammar rules, so now we'll talk about the special directives.</p> <p>Directives in Lemon can occur in any order. You can put them before the grammar rules, or after the grammar rules, or in the midst of the grammar rules. It doesn't matter. The relative order of directives used to assign precedence to terminals is important, but other than that, the order of directives in Lemon is arbitrary.</p> <p>Lemon supports the following special directives: <ul> <li><tt><a href='#pcode'>%code</a></tt> <li><tt><a href='#default_destructor'>%default_destructor</a></tt> <li><tt><a href='#default_type'>%default_type</a></tt> <li><tt><a href='#destructor'>%destructor</a></tt> <li><tt><a href='#pifdef'>%endif</a></tt> <li><tt><a href='#extraarg'>%extra_argument</a></tt> <li><tt><a href='#pfallback'>%fallback</a></tt> <li><tt><a href='#pifdef'>%ifdef</a></tt> <li><tt><a href='#pifdef'>%ifndef</a></tt> <li><tt><a href='#pinclude'>%include</a></tt> <li><tt><a href='#pleft'>%left</a></tt> <li><tt><a href='#pname'>%name</a></tt> <li><tt><a href='#pnonassoc'>%nonassoc</a></tt> <li><tt><a href='#parse_accept'>%parse_accept</a></tt> <li><tt><a href='#parse_failure'>%parse_failure</a></tt> <li><tt><a href='#pright'>%right</a></tt> <li><tt><a href='#stack_overflow'>%stack_overflow</a></tt> <li><tt><a href='#stack_size'>%stack_size</a></tt> <li><tt><a href='#start_symbol'>%start_symbol</a></tt> <li><tt><a href='#syntax_error'>%syntax_error</a></tt> <li><tt><a href='#token_class'>%token_class</a></tt> <li><tt><a href='#token_destructor'>%token_destructor</a></tt> <li><tt><a href='#token_prefix'>%token_prefix</a></tt> <li><tt><a href='#token_type'>%token_type</a></tt> <li><tt><a href='#ptype'>%type</a></tt> <li><tt><a href='#pwildcard'>%wildcard</a></tt> </ul> Each of these directives will be described separately in the following sections:</p> <a name='pcode'></a> <h4>The <tt>%code</tt> directive</h4> <p>The <tt>%code</tt> directive is used to specify additional C code that is added to the end of the main output file. This is similar to the <tt><a href='#pinclude'>%include</a></tt> directive except that <tt>%include</tt> is inserted at the beginning of the main output file.</p> <p><tt>%code</tt> is typically used to include some action routines or perhaps a tokenizer or even the "main()" function as part of the output file.</p> <a name='default_destructor'></a> <h4>The <tt>%default_destructor</tt> directive</h4> <p>The <tt>%default_destructor</tt> directive specifies a destructor to use for non-terminals that do not have their own destructor specified by a separate <tt>%destructor</tt> directive. See the documentation on the <tt><a name='#destructor'>%destructor</a></tt> directive below for additional information.</p> <p>In some grammars, many different non-terminal symbols have the same data type and hence the same destructor.

The example shows a non-terminal named "nt" that holds values of type "void*". When the rule for an "nt" reduces, it sets the value of the non-terminal to space obtained from malloc(). Later, when the nt non-terminal is popped from the stack, the destructor will fire and call free() on this malloced space, thus avoiding a memory leak. (Note that the symbol "$$" in the destructor code is replaced by the value of the non-terminal.)</p> <p>It is important to note that the value of a non-terminal is passed to the destructor whenever the non-terminal is removed from the stack, unless the non-terminal is used in a C-code action. If the non-terminal is used by C-code, then it is assumed that the C-code will take care of destroying it. More commonly, the value is used to build some larger structure, and we don't want to destroy it, which is why the destructor is not called in this circumstance.</p> <p>Destructors help avoid memory leaks by automatically freeing allocated objects when they go out of scope. To do the same using yacc or bison is much more difficult.</p> <a name='extraarg'></a> <h4>The <tt>%extra_argument</tt> directive</h4> The <tt>%extra_argument</tt> directive instructs Lemon to add a 4th parameter to the parameter list of the Parse() function it generates. Lemon doesn't do anything itself with this extra argument, but it does make the argument available to C-code action routines, destructors, and so forth. For example, if the grammar file contains:</p> <p><pre> %extra_argument { MyStruct *pAbc } </pre></p> <p>Then the Parse() function generated will have an 4th parameter of type "MyStruct*" and all action routines will have access to a variable named "pAbc" that is the value of the 4th parameter in the most recent call to Parse().</p> <a name='pfallback'></a> <h4>The <tt>%fallback</tt> directive</h4> <p>The <tt>%fallback</tt> directive specifies an alternative meaning for one or more tokens. The alternative meaning is tried if the original token would have generated a syntax error.</p> <p>The <tt>%fallback</tt> directive was added to support robust parsing of SQL syntax in <a href='https://www.sqlite.org/'>SQLite</a>. The SQL language contains a large assortment of keywords, each of which appears as a different token to the language parser. SQL contains so many keywords that it can be difficult for programmers to keep up with them all. Programmers will, therefore, sometimes mistakenly use an obscure language keyword for an identifier. The <tt>%fallback</tt> directive provides a mechanism to tell the parser: "If you are unable to parse this keyword, try treating it as an identifier instead."</p> <p>The syntax of <tt>%fallback</tt> is as follows: <blockquote> <tt>%fallback</tt> <i>ID</i> <i>TOKEN...</i> <b>.</b> </blockquote></p> <p>In words, the <tt>%fallback</tt> directive is followed by a list of token names terminated by a period. The first token name is the fallback token — the token to which all the other tokens fall back to. The second and subsequent arguments are tokens which fall back to the token identified by the first argument.</p> <a name='pifdef'></a> <h4>The <tt>%ifdef</tt>, <tt>%ifndef</tt>, and <tt>%endif</tt> directives</h4> <p>The <tt>%ifdef</tt>, <tt>%ifndef</tt>, and <tt>%endif</tt> directives are similar to #ifdef, #ifndef, and #endif in the C-preprocessor, just not as general. Each of these directives must begin at the left margin. No whitespace is allowed between the "%" and the directive name.</p> <p>Grammar text in between "<tt>%ifdef MACRO</tt>" and the next nested "<tt>%endif</tt>" is ignored unless the "-DMACRO" command-line option is used. Grammar text betwen "<tt>%ifndef MACRO</tt>" and the next nested "<tt>%endif</tt>" is included except when the "-DMACRO" command-line option is used.</p> <p>Note that the argument to <tt>%ifdef</tt> and <tt>%ifndef</tt> must be a single preprocessor symbol name, not a general expression. There is no "<tt>%else</tt>" directive.</p> <a name='pinclude'></a> <h4>The <tt>%include</tt> directive</h4> <p>The <tt>%include</tt> directive specifies C code that is included at the top of the generated parser. You can include any text you want — the Lemon parser generator copies it blindly. If you have multiple <tt>%include</tt> directives in your grammar file, their values are concatenated so that all <tt>%include</tt> code ultimately appears near the top of the generated parser, in the same order as it appeared in the grammar.</p> <p>The <tt>%include</tt> directive is very handy for getting some extra #include preprocessor statements at the beginning of the generated parser. For example:</p> <p><pre> %include {#include <unistd.h>} </pre></p> <p>This might be needed, for example, if some of the C actions in the grammar call functions that are prototyped in unistd.h.</p> <a name='pleft'></a> <h4>The <tt>%left</tt> directive</h4> The <tt>%left</tt> directive is used (along with the <tt><a href='#pright'>%right</a></tt> and <tt><a href='#pnonassoc'>%nonassoc</a></tt> directives) to declare precedences of terminal symbols. Every terminal symbol whose name appears after a <tt>%left</tt> directive but before the next period (".") is given the same left-associative precedence value. Subsequent <tt>%left</tt> directives have higher precedence. For example:</p> <p><pre> %left AND. %left OR. %nonassoc EQ NE GT GE LT LE. %left PLUS MINUS. %left TIMES DIVIDE MOD. %right EXP NOT. </pre></p> <p>Note the period that terminates each <tt>%left</tt>, <tt>%right</tt> or <tt>%nonassoc</tt> directive.</p> <p>LALR(1) grammars can get into a situation where they require a large amount of stack space if you make heavy use or right-associative operators. For this reason, it is recommended that you use <tt>%left</tt> rather than <tt>%right</tt> whenever possible.</p> <a name='pname'></a> <h4>The <tt>%name</tt> directive</h4> <p>By default, the functions generated by Lemon all begin with the five-character string "Parse". You can change this string to something different using the <tt>%name</tt> directive. For instance:</p> <p><pre> %name Abcde </pre></p> <p>Putting this directive in the grammar file will cause Lemon to generate functions named <ul> <li> AbcdeAlloc(), <li> AbcdeFree(), <li> AbcdeTrace(), and <li> Abcde(). </ul> The <tt>%name</tt> directive allows you to generate two or more different parsers and link them all into the same executable.</p> <a name='pnonassoc'></a> <h4>The <tt>%nonassoc</tt> directive</h4> <p>This directive is used to assign non-associative precedence to one or more terminal symbols. See the section on <a href='#precrules'>precedence rules</a> or on the <tt><a href='#pleft'>%left</a></tt> directive for additional information.</p> <a name='parse_accept'></a> <h4>The <tt>%parse_accept</tt> directive</h4> <p>The <tt>%parse_accept</tt> directive specifies a block of C code that is executed whenever the parser accepts its input string. To "accept" an input string means that the parser was able to process all tokens without error.</p> <p>For example:</p> <p><pre> %parse_accept { printf("parsing complete!\n"); } </pre></p> <a name='parse_failure'></a> <h4>The <tt>%parse_failure</tt> directive</h4> <p>The <tt>%parse_failure</tt> directive specifies a block of C code that is executed whenever the parser fails complete. This code is not executed until the parser has tried and failed to resolve an input error using is usual error recovery strategy. The routine is only invoked when parsing is unable to continue.</p> <p><pre> %parse_failure { fprintf(stderr,"Giving up. Parser is hopelessly lost...\n"); } </pre></p> <a name='pright'></a> <h4>The <tt>%right</tt> directive</h4> <p>This directive is used to assign right-associative precedence to one or more terminal symbols. See the section on <a href='#precrules'>precedence rules</a> or on the <a href='#pleft'>%left</a> directive for additional information.</p> <a name='stack_overflow'></a> <h4>The <tt>%stack_overflow</tt> directive</h4> <p>The <tt>%stack_overflow</tt> directive specifies a block of C code that is executed if the parser's internal stack ever overflows. Typically this just prints an error message. After a stack overflow, the parser will be unable to continue and must be reset.</p> <p><pre> %stack_overflow { fprintf(stderr,"Giving up. Parser stack overflow\n"); } </pre></p> <p>You can help prevent parser stack overflows by avoiding the use of right recursion and right-precedence operators in your grammar. Use left recursion and and left-precedence operators instead to encourage rules to reduce sooner and keep the stack size down. For example, do rules like this: <pre> list ::= list element. // left-recursion. Good! list ::= . </pre> Not like this: <pre> list ::= element list. // right-recursion. Bad! list ::= . </pre></p> <a name='stack_size'></a> <h4>The <tt>%stack_size</tt> directive</h4> <p>If stack overflow is a problem and you can't resolve the trouble by using left-recursion, then you might want to increase the size of the parser's stack using this directive. Put an positive integer after the <tt>%stack_size</tt> directive and Lemon will generate a parse with a stack of the requested size. The default value is 100.</p> <p><pre> %stack_size 2000 </pre></p> <a name='start_symbol'></a> <h4>The <tt>%start_symbol</tt> directive</h4> <p>By default, the start symbol for the grammar that Lemon generates is the first non-terminal that appears in the grammar file. But you can choose a different start symbol using the <tt>%start_symbol</tt> directive.</p> <p><pre> %start_symbol prog </pre></p> <a name='syntax_error'></a> <h4>The <tt>%syntax_error</tt> directive</h4> <p>See <a href='#error_processing'>Error Processing</a>.</p> <a name='token_class'></a> <h4>The <tt>%token_class</tt> directive</h4> <p>Undocumented. Appears to be related to the MULTITERMINAL concept. <a href='http://sqlite.org/src/fdiff?v1=796930d5fc2036c7&v2=624b24c5dc048e09&sbs=0'>Implementation</a>.</p> <a name='token_destructor'></a> <h4>The <tt>%token_destructor</tt> directive</h4> <p>The <tt>%destructor</tt> directive assigns a destructor to a non-terminal symbol. (See the description of the <tt><a href='%destructor'>%destructor</a></tt> directive above.) The <tt>%token_destructor</tt> directive does the same thing for all terminal symbols.</p> <p>Unlike non-terminal symbols which may each have a different data type for their values, terminals all use the same data type (defined by the <tt><a href='#token_type'>%token_type</a></tt> directive) and so they use a common destructor. Other than that, the token destructor works just like the non-terminal destructors.</p> <a name='token_prefix'></a> <h4>The <tt>%token_prefix</tt> directive</h4> <p>Lemon generates #defines that assign small integer constants to each terminal symbol in the grammar. If desired, Lemon will add a prefix specified by this directive to each of the #defines it generates.</p> <p>So if the default output of Lemon looked like this: <pre> #define AND 1 #define MINUS 2 #define OR 3 #define PLUS 4 </pre> You can insert a statement into the grammar like this: <pre> %token_prefix TOKEN_ </pre> to cause Lemon to produce these symbols instead: <pre> #define TOKEN_AND 1 #define TOKEN_MINUS 2 #define TOKEN_OR 3 #define TOKEN_PLUS 4 </pre></p> <a name='token_type'></a><a name='ptype'></a> <h4>The <tt>%token_type</tt> and <tt>%type</tt> directives</h4> <p>These directives are used to specify the data types for values on the parser's stack associated with terminal and non-terminal symbols. The values of all terminal symbols must be of the same type. This turns out to be the same data type as the 3rd parameter to the Parse() function generated by Lemon. Typically, you will make the value of a terminal symbol by a pointer to some kind of token structure. Like this:</p> <p><pre> %token_type {Token*} </pre></p> <p>If the data type of terminals is not specified, the default value is "void*".</p> <p>Non-terminal symbols can each have their own data types. Typically the data type of a non-terminal is a pointer to the root of a parse tree structure that contains all information about that non-terminal. For example:</p> <p><pre> %type expr {Expr*} </pre></p> <p>Each entry on the parser's stack is actually a union containing instances of all data types for every non-terminal and terminal symbol. Lemon will automatically use the correct element of this union depending on what the corresponding non-terminal or terminal symbol is. But the grammar designer should keep in mind that the size of the union will be the size of its largest element. So if you have a single non-terminal whose data type requires 1K of storage, then your 100 entry parser stack will require 100K of heap space. If you are willing and able to pay that price, fine. You just need to know.</p> <a name='pwildcard'></a> <h4>The <tt>%wildcard</tt> directive</h4> <p>The <tt>%wildcard</tt> directive is followed by a single token name and a period. This directive specifies that the identified token should match any input token.</p> <p>When the generated parser has the choice of matching an input against the wildcard token and some other token, the other token is always used. The wildcard token is only matched if there are no alternatives.</p> <a name='error_processing'></a> <h3>Error Processing</h3> <p>After extensive experimentation over several years, it has been discovered that the error recovery strategy used by yacc is about as good as it gets. And so that is what Lemon uses.</p> <p>When a Lemon-generated parser encounters a syntax error, it first invokes the code specified by the <tt>%syntax_error</tt> directive, if any. It then enters its error recovery strategy. The error recovery strategy is to begin popping the parsers stack until it enters a state where it is permitted to shift a special non-terminal symbol named "error". It then shifts this non-terminal and continues parsing. The <tt>%syntax_error</tt> routine will not be called again until at least three new tokens have been successfully shifted.</p> <p>If the parser pops its stack until the stack is empty, and it still is unable to shift the error symbol, then the <tt><a href='#parse_failure'>%parse_failure</a></tt> routine is invoked and the parser resets itself to its start state, ready to begin parsing a new file. This is what will happen at the very first syntax error, of course, if there are no instances of the "error" non-terminal in your grammar.</p> </body> </html> |

They are computed doing ** a single search from the root to a leaf, counting the number of cells ** at each level, and assuming that unvisited pages have a similar number ** of cells. ** ** The sqlite_dbpage virtual table must be available for this virtual table ** to operate. ** ** USAGE EXAMPLES: ** ** Show the table btrees in a schema order with the tables with the most ** rows occuring first: ** ** SELECT name, nEntry ** FROM sqlite_btreeinfo ** WHERE type='table' ** ORDER BY nEntry DESC, name; ** ** Show the names of all WITHOUT ROWID tables: ** ** SELECT name FROM sqlite_btreeinfo ** WHERE type='table' AND NOT hasRowid; */ #if !defined(SQLITEINT_H) #include "sqlite3ext.h" #endif SQLITE_EXTENSION_INIT1 #include <string.h> #include <assert.h> /* Columns available in this virtual table */ #define BINFO_COLUMN_TYPE 0 #define BINFO_COLUMN_NAME 1 #define BINFO_COLUMN_TBL_NAME 2 #define BINFO_COLUMN_ROOTPAGE 3 #define BINFO_COLUMN_SQL 4 #define BINFO_COLUMN_HASROWID 5 #define BINFO_COLUMN_NENTRY 6 #define BINFO_COLUMN_NPAGE 7 #define BINFO_COLUMN_DEPTH 8 #define BINFO_COLUMN_SZPAGE 9 #define BINFO_COLUMN_SCHEMA 10 /* Forward declarations */ typedef struct BinfoTable BinfoTable; typedef struct BinfoCursor BinfoCursor; /* A cursor for the sqlite_btreeinfo table */ struct BinfoCursor { sqlite3_vtab_cursor base; /* Base class.

> > > > > > > > > > > > > > > > | 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 | This folder contains extensions and utility programs intended to analyze live database files, detect problems, and possibly fix them. As SQLite is being used on larger and larger databases, database sizes are growing into the terabyte range. At that size, hardware malfunctions and/or cosmic rays will occasionally corrupt a database file. Detecting problems and fixing errors a terabyte-sized databases can take hours or days, and it is undesirable to take applications that depend on the databases off-line for such a long time. The utilities in the folder are intended to provide mechanisms for detecting and fixing problems in large databases while those databases are in active use. The utilities and extensions in this folder are experimental and under active development at the time of this writing (2017-10-12). If and when they stabilize, this README will be updated to reflect that fact. |

Was: ** (2) If the subquery is an aggregate then ** (2a) the outer query must not be a join and ** (2b) the outer query must not use subqueries ** other than the one FROM-clause subquery that is a candidate ** for flattening. (This is due to ticket [2f7170d73bf9abf80] ** from 2015-02-09.) ** ** (3) If the subquery is the right operand of a LEFT JOIN then ** (3a) the subquery may not be a join and ** (3b) the FROM clause of the subquery may not contain a virtual ** table and ** (3c) the outer query may not be an aggregate. ** ** (4) The subquery can not be DISTINCT. ** ** (**) At one point restrictions (4) and (5) defined a subset of DISTINCT ** sub-queries that were excluded from this optimization. Restriction ** (4) has since been expanded to exclude all DISTINCT subqueries. ** ** (**) We no longer attempt to flatten aggregate subqueries. Was: ** If the subquery is aggregate, the outer query may not be DISTINCT. ** ** (7) The subquery must have a FROM clause. TODO: For subqueries without ** A FROM clause, consider adding a FROM clause with the special ** table sqlite_once that consists of a single row containing a ** single NULL. ** ** (8) If the subquery uses LIMIT then the outer query may not be a join. ** ** (9) If the subquery uses LIMIT then the outer query may not be aggregate. ** ** (**) Restriction (10) was removed from the code on 2005-02-05 but we ** accidently carried the comment forward until 2014-09-15. Original ** constraint: "If the subquery is aggregate then the outer query ** may not use LIMIT." ** ** (11) The subquery and the outer query may not both have ORDER BY clauses. ** ** (**) Not implemented. Subsumed into restriction (3). Was previously ** a separate restriction deriving from ticket #350. ** ** (13) The subquery and outer query may not both use LIMIT. ** ** (14) The subquery may not use OFFSET. ** ** (15) If the outer query is part of a compound select, then the ** subquery may not use LIMIT. ** (See ticket #2339 and ticket [02a8e81d44]). ** ** (16) If the outer query is aggregate, then the subquery may not ** use ORDER BY. (Ticket #2942) This used to not matter ** until we introduced the group_concat() function. ** ** (17) If the subquery is a compound select, then ** (17a) all compound operators must be a UNION ALL, and ** (17b) no terms within the subquery compound may be aggregate ** or DISTINCT, and ** (17c) every term within the subquery compound must have a FROM clause ** (17d) the outer query may not be ** (17d1) aggregate, or ** (17d2) DISTINCT, or ** (17d3) a join. ** ** The parent and sub-query may contain WHERE clauses. Subject to ** rules (11), (13) and (14), they may also contain ORDER BY, ** LIMIT and OFFSET clauses. The subquery cannot use any compound ** operator other than UNION ALL because all the other compound ** operators have an implied DISTINCT which is disallowed by ** restriction (4). ** ** Also, each component of the sub-query must return the same number ** of result columns. This is actually a requirement for any compound ** SELECT statement, but all the code here does is make sure that no ** such (illegal) sub-query is flattened. The caller will detect the ** syntax error and return a detailed message. ** ** (18) If the sub-query is a compound select, then all terms of the ** ORDER BY clause of the parent must be simple references to ** columns of the sub-query. ** ** (19) If the subquery uses LIMIT then the outer query may not ** have a WHERE clause. ** ** (20) If the sub-query is a compound select, then it must not use ** an ORDER BY clause. Ticket #3773. We could relax this constraint ** somewhat by saying that the terms of the ORDER BY clause must ** appear as unmodified result columns in the outer query. But we ** have other optimizations in mind to deal with that case. ** ** (21) If the subquery uses LIMIT then the outer query may not be ** DISTINCT. (See ticket [752e1646fc]). ** ** (22) The subquery may not be a recursive CTE. ** ** (**) Subsumed into restriction (17d3). Was: If the outer query is ** a recursive CTE, then the sub-query may not be a compound query. ** This restriction is because transforming the ** parent to a compound query confuses the code that handles ** recursive queries in multiSelect(). ** ** (**) We no longer attempt to flatten aggregate subqueries. Was: ** The subquery may not be an aggregate that uses the built-in min() or ** or max() functions.
