23:45
Do not mark the ephemeral tables used to hold the RHS of IN clauses as unordered because the NGQP will use those ephemeral tables to help order the output.

18:31
Fix harmless compiler warnings. check-in: dea2ca6a user: drh tags: trunk

2014-01-21
22:25
Change the recursive common table expression algorithm to use a queue instead of a pair of tables. Runs about 25% faster on the sudoku solver query. The OP_SwapCursors opcode is no longer required. The current implementation uses just a fifo, but the plan is to change it into a queue that will support ORDER BY and LIMIT in a recursive query. check-in: b2671e11 user: drh tags: cte-via-queue

Remove the undocumented requirement for applications that use an SQLITE_ENABLE_SQLLOG build to define a sqlite3_init_sqllog() function. check-in: 5e43bf01 user: dan tags: trunk
2014-01-20
19:55

14:58
Remove an unused #define and add an assert(), both associated with WITH logic. check-in: a06235e0 user: drh tags: trunk

2014-01-17
20:36
Add extra tests to with2.test. check-in: eecc325a user: dan tags: trunk
18:34
Minor simplification of error message text for a couple of errors associated with WITH clause processing. check-in: 2031004d user: drh tags: trunk
17:40
Resolve table names within CTEs in the context in which the CTE is declared, not the context in which it is used. check-in: a7323838 user: dan tags: trunk
16:19
Add tests that verify that keywords WITH, WITHOUT, and RECURSIVE can still be used as table and column names. check-in: 9ca18a01 user: drh tags: trunk

21:02
Improve the error messages used to report illegal recursive cte references. check-in: 54eee9fe user: dan tags: common-table-expr

15:31
Always use available indices to optimize LIKE operators even if the pattern of the LIKE operator has a COLLATE modifier. This fixes an ineffiency that was introduced into 3.7.15 by check-in [8542e6180d4] on 2012-12-08. check-in: 16bd5478 user: drh tags: trunk
10:58

18:12
When resolving names, consider a reference to a recursive CTE column as equivalent to a reference to the outermost name-context. This ensures that correlated sub-queries are correctly identified as such. check-in: 61be2da0 user: dan tags: common-table-expr
15:27
Return an error if a CTE specifies a different number of columns than its SELECT statement returns. check-in: 9a514b50 user: dan tags: common-table-expr

2014-01-14
20:14
Add code to handle recursive CTEs. check-in: a5c2a54a user: dan tags: common-table-expr
10:17
Fix harmless compiler warning in LEMON. check-in: f61a7058 user: mistachkin tags: trunk
10:17
For the Win32 VFS, defining winShmMutexHeld should be controlled by NDEBUG, not SQLITE_DEBUG. check-in: 1e131094 user: mistachkin tags: trunk
2014-01-13
20:38
In the command-line shell, defend against a NULL-pointer dereference in the case where sqlite3_column_name() returns NULL (as might happen following an OOM error). check-in: ac15455a user: drh tags: trunk
20:32
For statements of just an unadorned VALUES clause, assign column names as "columnN" for increasing whole numbers N. check-in: 260587d2 user: drh tags: trunk
16:36
Fix some memory leaks and crashes that could follow an OOM condition during WITH clause parsing. check-in: 8839850c user: dan tags: common-table-expr

19:19
Update the parser so that sub-queries and CTEs may have WITH clauses. check-in: 704d3931 user: dan tags: common-table-expr
13:22
Parse common table expressions. But do not do anything with them (yet). check-in: da98b720 user: drh tags: common-table-expr
12:52
In LEMON, limit the size of the grammar file to 100MB. This ensures that the program will never experience integer overflow. To be doubly sure, use calloc() instead of malloc() when allocating arrays. check-in: 29ba458d user: drh tags: trunk
03:54
Optimizations to the SQL language grammar that result in a small size reduction and speed increase. check-in: cb5d1f83 user: drh tags: trunk
03:27
Add the "%token_class" directive to the LEMON parser generator. This opens up the possibility of simplifying the parser. Also remove all calls to sprintf(), strcpy(), and strcat() from LEMON to avoid compiler warnings on OpenBSD. (Aside: It is this change to avoid harmless compiler warnings that was the cause of the reason spat of bugs.) check-in: 8eb48c04 user: drh tags: trunk
03:06
In LEMON, fix a bug in the text formatter introduced by the previous commit. Also add the new "%token_class" directive for defining symbolic names that stand any one of a collection of tokens. Closed-Leaf check-in: da7890ca user: drh tags: lemon-updates
2014-01-10
23:21
Do not use sprintf(), strcpy() or strcat() in the implementation of the lemon parser generator tool, to avoid compiler warnings in OpenBSD. check-in: e43c522d user: drh tags: lemon-updates
20:51
Remove unused structure definition from parse.y. check-in: 7f1e7ae3 user: drh tags: trunk
