drhc6b52df2002-01-04 03:09:29 +0000[diff] [blame]21<li>Bug fix: An attempt to delete a single row of a table with a WHERE
22 clause of "ROWID=x" when no such rowid exists was causing an error.</li>
drhe638bbf2002-01-07 19:04:21 +0000[diff] [blame^]23<li>Bug fix: Passing in a NULL as the 3rd parameter to <b>sqlite_open()</b>
24 would sometimes cause a coredump.</li>

29 key in underlying B-Tree representation of the table.</li>
30<li>Several obscure, unrelated bugs were found and fixed while
31 implemented the integer primary key change of the previous bullet.</li>
drh7c917d12001-12-16 20:05:05 +0000[diff] [blame]32<li>Added the ability to specify "*" as part of a larger column list in
33 the result section of a SELECT statement. For example:
34 <nobr>"<b>SELECT rowid, * FROM table1;</b>"</nobr>.</li>

39<li>Fix a bug in <b>CREATE TEMPORARY TABLE</b> which was causing the
40 table to be initially allocated in the main database file instead
41 of in the separate temporary file. This bug could cause the library
drhc38f3d52001-12-15 03:00:42 +0000[diff] [blame]42 to suffer an assertion failure and it could cause "page leaks" in the
drh4cbd68f2001-12-15 02:58:18 +0000[diff] [blame]43 main database file.
44<li>Fix a bug in the b-tree subsystem that could sometimes cause the first
45 row of a table to be repeated during a database scan.</li>

49<li>Fix the locking mechanism yet again to prevent
50 <b>sqlite_exec()</b> from returning SQLITE_PROTOCOL

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

84 unreadable after a DROP TABLE due to corruption to the SQLITE_MASTER
85 table.</li>
86<li>Change the code so that version 2.1.1 databases that were rendered
87 unreadable by the above bug can be read by this version of
88 the library even though the SQLITE_MASTER table is (slightly)
89 corrupted.</li>

118 fix a bug in the round() function.</li>

174 newlines anywhere in the data. This is an old bug that was carried
175 forward from version 1.0. To fix it, the ".dump" output no longer
176 uses the COPY command. It instead generates INSERT statements.</li>
177<li>Extend the expression syntax to support "expr NOT NULL" (with a
