  the locking statement of the underlying database files shall remain
  unchanged by the BEGIN TRANSACTION statement.

<h1>SQLite Syntax Requirements</h1>

<p>These requirements make the distinction between "preparing" an
SQL statement and "evaluating" or "invoking" an SQL statement.
Preparation means that the SQL statement text is translated into
an internal binary representation that is more suitable for processing.
Evaluation or invocation means that the processing is actually carried out.
Preparation of an SQL statement is usually accomplished by interfaces
[sqlite3_prepare()], [sqlite3_prepare16()], or [sqlite3_prepare_v2()] and
evaluation or invocation of an SQLite statement is accomplished by
calling [sqlite3_step()].  However, if a statement is initially
prepared using [sqlite3_prepare_v2()] and a change to the database
schema is detected during evaluation, then the preparation is redone
automatically, by [sqlite3_step()].  So even though it is reasonable
to think about preparation as being a function of [sqlite3_prepare_v2()]
and its companions and evaluation as being a function of
[sqlite3_step()], the reader should keep in mind that
[sqlite3_step()] might also sometimes do preparations following
schema changes.</p>

<tcl>
syntaxreq {H42000} {} {
  SQLite expects all statements to be terminated by a semicolon.
  If a statement is submitted to SQLite that does not end in a
  semicolon, then a semicolon is added automatically by the tokenizer.
  (See [H41040].)
} {
  The SQLite parser shall accept SQL statements consisting of an SQL command
  followed by a semicolon.
} {
  sql_statement ::= cmd SEMI.
}
syntaxreq {H42002} {} {
  Acceptance by the parser does not imply that the SQL statement
  will be accepted by SQLite.  SQL statements may be rejected by other
  parts of the SQLite library.  Acceptance by the parser is a necessary
  but not a sufficient condition for the statement to work.
} {
  The preparation of an SQL statement that is not accepted by
  the SQLite parser shall fail with an error.
}
syntaxreq {H42004} {} {
  SQLite ignores case when comparing ASCII characters in identifiers and
  in type names.  (The rules for comparison of content are different.)
  Case is considered for other unicode characters, however.
  Hence, SQLite considers identifiers "A" and "a" to be equivalent but
  "&Aring;" and "&aring;" are distinct.
} {
  SQLite shall use the built-in NOCASE collating sequence when comparing
  identifiers and datatype names within SQL statements during 
  statement preparation.
}
