Add the SQLITE_DBCONFIG_RESET_DATABASE control as a replacement for the reset_database pragma. Resetting the database should be hard enough to do that it cannot be done by accident. Leaf check-in: ff836cb8 user: drh tags: reset-database
11:22
Merge updates from trunk. check-in: 94877e49 user: drh tags: reset-database
04:16

04:10
Fix compiler warnings in FTS3. check-in: de508e83 user: drh tags: trunk
01:46

01:27
Add the "PRAGMA reset_database=ON|OFF" command. When on, it causes the database to appear to be empty, causing the next transaction to reset it to an empty database. check-in: 02e1a13c user: drh tags: reset-database
2018-04-27
22:42

17:39
Add the ability to use bind parameters in the CLI. The new ".set KEY=VALUE" dot-command works to set bindings. Or use the "-Dkey=value" command-line option. Or use the built-in shell_bindings(k,v) virtual table to set, delete, or changing bindings. check-in: 1f2944d1 user: drh tags: shell-bindings

18:34
The previous fix for ticket [d85fffd6ffe856092ed8da] in check-in [0a514e62ad1ebe5c12da8dae] did not completely address the probably in that it only worked for cases where the OP_SCopy that loaded the register was the last instruction in the sequence for the expression, which is not necessarily the case for expressions like CASE...END. This revision prevents the registered that will be recomputed from being cached in the first place. check-in: 9fd0faf5 user: drh tags: trunk

12:01
Avoid many unnecessary calls to sqlite3ReadSchema() and sqlite3Init() when the schema is known to be valid already. check-in: 58cf812f user: drh tags: trunk

13:07
Enhance the CLI to render EXPLAIN QUERY PLAN using an ASCII-art graph. This works with ".eqp" modes and when the query begins with exactly "EXPLAIN QUERY PLAN".
