17 check-ins using file src/vdbeaux.c version e85c8c7d

2009-11-12
17:52
Factor out the IN operator code generation into a subroutine. Use this subroutine to implement both logic and branching versions of the IN operator. check-in: fcff5b7e user: drh tags: trunk
13:32
Factor out the code generator for BETWEEN into a subroutine. check-in: 5735f60b user: drh tags: trunk
05:04
Update comment for substrFunc(). Added additional SUBSTR() test cases. check-in: d7b3801d user: shaneh tags: trunk
04:26
Suppress unnecessary OP_Noop instructions on when the right table of a LEFT JOIN uses the index-only optimization. check-in: e8aec08b user: drh tags: trunk
03:46
Suppress excess OP_Null opcodes caused by binary IS or IS NOT operators that are converted into unary ISNULL or NOTNULL operators. check-in: cff1b36a user: drh tags: trunk
03:13
Adjustments to the implementation of LIMIT so that it uses fewer opcodes. check-in: 39d5b292 user: drh tags: trunk
2009-11-11
23:58
If the sector size is unspecified (initially 0) then set it to 512, not to 32. check-in: 8861b5c1 user: drh tags: trunk
23:48
Remove an obsolete (and incorrect) comment from sqlite3MemCompare(). No changes to code. check-in: c15b70b3 user: drh tags: trunk
20:53
Tweaks to the SUBSTR() function to make it dramatically faster in the common case where the input string is large but the 2nd and 3rd arguments are small positive integers. check-in: 5a474a86 user: drh tags: trunk
13:17
Allow media sector sizes as small as 32. The former minimum size was 512. check-in: 5a32bfc1 user: drh tags: trunk
04:17
Modified CLI to raise an error when extra command line options are passed. Added tests to verify correct handling, as well as other basic handling of command line options. Ticket [f5cb008a65]. check-in: 09b4f19f user: shaneh tags: trunk
01:14
Additional test cases for the coalesce() and ifnull() functions. check-in: d0591258 user: drh tags: trunk
00:24
Generate VDBE code for the built-in COALESCE() and IFNULL() functions. This allows unused arguments to never be evaluated, which is a performance win when the unused argument is a subquery. check-in: 30055b25 user: drh tags: trunk
2009-11-10
17:55
Additional intarray test cases and tweaks to comments. check-in: 0c8db5d8 user: drh tags: trunk
17:24
Initial implementation and test cases for the "intarray" virtual table. check-in: 0e7d2925 user: drh tags: trunk
17:07
Fix for datbase name being ignored with the -batch option in the CLI. Ticket [aeff892c57]. check-in: 8097c64a user: shaneh tags: trunk
01:30
Remove the obsolete "$Id:$" RCS identifier strings from the source code. check-in: f6c045f6 user: drh tags: trunk
