Experimental implementation of NULLS FIRST/LAST. This branch still has problems - the most significant of which is that ORDER BY clauses with a non-default NULLS FIRST/LAST qualifier can never use an index. check-in: 07babb0f89 user: dan tags: nulls-last
16:25
For the ".testctrl prng_seed" command in the CLI, if the argument is "random" then select a random integer seed and print the seed value on stdout. check-in: 636ca4472c user: drh tags: trunk

01:59
Modify signature of sqlite3VdbeChangeOpcode() to accept int instead of u32. check-in: 68b7f2acf4 user: mistachkin tags: trunk

19:40
Fix harmless compiler warnings. check-in: 1eef4ddea9 user: drh tags: trunk
19:19
Remove support for SQLITE_ENABLE_STAT3. The sqlite_stat3 table is now ignored, if it exists. Run ANALYZE using STAT4 to get the equivalent functionality, which presumably everybody has been doing for a long time now. check-in: f1cd234c98 user: drh tags: trunk
18:49
Fix a case of the Expr.affinity to Expr.affExpr refactor that was missed in the [a29f2a7d07beff64] check-in. check-in: 83450d1070 user: drh tags: trunk
16:23
More legacy STAT3 code removed. Closed-Leaf check-in: 845d2f17de user: drh tags: omit-stat3
15:47
Fix spurious "no such table: x1" errors in shared-schema mode that could occur when a query that is a join across two or more databases needs to call the xConnect() methods of a virtual table. check-in: edf45cd7c6 user: dan tags: reuse-schema
15:24
Remove support for STAT3. The sqlite_stat3 tables are ignored, if they exist. STAT4 continues to work as it always has, and as it is a superset of STAT3 is the recommended replacement. check-in: 1e17ea2fd1 user: drh tags: omit-stat3
11:44
Fix a bug causing "no such table" and other similar sqlite3_prepare*() errors to return SQLITE_SCHEMA instead of SQLITE_ERROR in shared-schema mode when there is an attached database for which the schema has never been loaded. check-in: 111e2c73cf user: dan tags: reuse-schema
01:39
Remove a NEVER() that is reachable from a corrupt database. check-in: 30e6ee27a9 user: drh tags: trunk
