31<li>Bug fix: There was an incorrect assert() in pager.c. The real code was
32 all correct (as far as is known) so everything should work OK if you
33 compile with -DNDEBUG=1. But without disability the assertions, there
34 could be a fault.</li>

44<li>Fix a serious bug in the INSERT command which was causing data to go
45 into the wrong columns if the data source was a SELECT and the INSERT
46 clauses specified its columns in some order other than the default.</li>
drhb419a922002-01-30 16:17:23 +0000[diff] [blame]47<li>Added the ability to resolve constraint conflicts is ways other than
48 an abort and rollback. See the documentation on the "ON CONFLICT"
49 clause for details.</li>
drhfa86c412002-02-02 15:01:15 +0000[diff] [blame]50<li>Temporary files are now automatically deleted by the operating system
51 when closed. There are no more dangling temporary files on a program
52 crash. (If the OS crashes, fsck will delete the file after reboot
53 under Unix. I do not know what happens under Windows.)</li>
drhb419a922002-01-30 16:17:23 +0000[diff] [blame]54<li>NOT NULL constraints are honored.</li>

drh24e97df2002-02-03 19:06:02 +0000[diff] [blame]57<li>Added the SANITY_CHECK pragma.</li>

drhe638bbf2002-01-07 19:04:21 +0000[diff] [blame]95<li>Bug fix: Passing in a NULL as the 3rd parameter to <b>sqlite_open()</b>

drh7c917d12001-12-16 20:05:05 +0000[diff] [blame]107<li>Added the ability to specify "*" as part of a larger column list in

114<li>Fix a bug in <b>CREATE TEMPORARY TABLE</b> which was causing the
115 table to be initially allocated in the main database file instead
116 of in the separate temporary file. This bug could cause the library
drhc38f3d52001-12-15 03:00:42 +0000[diff] [blame]117 to suffer an assertion failure and it could cause "page leaks" in the
drh4cbd68f2001-12-15 02:58:18 +0000[diff] [blame]118 main database file.

125 <b>sqlite_exec()</b> from returning SQLITE_PROTOCOL

134 in the POSIX locking code and should not effect windows users.</li>

149 (ex: "<b>&lt</b>", "<b>==</b>", etc.)

605<li>All database files to be modified by an UPDATE, INSERT or DELETE are
606now locked before any changes are made to any files.
607This makes it safe (I think) to access
608the same database simultaneously from multiple processes.</li>
609<li>The code appears stable so we are now calling it "beta".</li>

614(or threads)
615can access the same database simultaneously. More work needed in
616this area, though.</li>

628but it uses Unix shell globbing wildcards instead of the '%'
629and '_' wildcards of SQL.</li>
630<li>Added the <B>COPY</b> command patterned after
631<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
632can now read the output of the <b>pg_dump</b> database dump utility
633of PostgreSQL.</li>

635<b>gdbm_reorganize()</b> function on the underlying database
