22 had the same name as a permanent table created by a separate process.</li>

drhc6b52df2002-01-04 03:09:29 +000026<li>Bug fix: An attempt to delete a single row of a table with a WHERE
27 clause of "ROWID=x" when no such rowid exists was causing an error.</li>
drhe638bbf2002-01-07 19:04:21 +000028<li>Bug fix: Passing in a NULL as the 3rd parameter to <b>sqlite_open()</b>
29 would sometimes cause a coredump.</li>
drh74e24cd2002-01-09 03:19:59 +000030<li>Bug fix: DROP TABLE followed by a CREATE TABLE with the same name all
31 within a single transaction was causing a coredump.</li>
32<li>Makefile updates from A. Rottmann</li>

36<li>Columns of type INTEGER PRIMARY KEY are actually used as the primary
37 key in underlying B-Tree representation of the table.</li>
38<li>Several obscure, unrelated bugs were found and fixed while
39 implemented the integer primary key change of the previous bullet.</li>
drh7c917d12001-12-16 20:05:05 +000040<li>Added the ability to specify "*" as part of a larger column list in
41 the result section of a SELECT statement. For example:

47<li>Fix a bug in <b>CREATE TEMPORARY TABLE</b> which was causing the
48 table to be initially allocated in the main database file instead
49 of in the separate temporary file. This bug could cause the library
drhc38f3d52001-12-15 03:00:42 +000050 to suffer an assertion failure and it could cause "page leaks" in the
drh4cbd68f2001-12-15 02:58:18 +000051 main database file.
52<li>Fix a bug in the b-tree subsystem that could sometimes cause the first
53 row of a table to be repeated during a database scan.</li>

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

60 the locking code. This change effects both POSIX and Windows users.</li>

66 unnecessarily. This time the bug was
67 in the POSIX locking code and should not effect windows users.</li>

drhf5bf0a72001-11-23 00:24:12 +000091<li>Fix a bug that could (rarely) cause the database to become
92 unreadable after a DROP TABLE due to corruption to the SQLITE_MASTER
93 table.</li>
94<li>Change the code so that version 2.1.1 databases that were rendered
95 unreadable by the above bug can be read by this version of
96 the library even though the SQLITE_MASTER table is (slightly)
97 corrupted.</li>

125<li>Patches from Christian Werner to improve ODBC compatibility and to
126 fix a bug in the round() function.</li>
127<li>Plug some memory leaks that use to occur if malloc() failed.
128 We have been and continue to be memory leak free as long as
129 malloc() works.</li>
130<li>Changes to some test scripts so that they work on Windows in

157<li>Bug fix: an assertion was failing if the disk holding the database
158 file became full or stopped accepting writes for some other reason.
159 New tests were added to detect similar problems in the future.</li>
drhbf4133c2001-10-13 02:59:08 +0000160<li>Added new operators: <b>&amp;</b> (bitwise-and)

drh382c0242001-10-06 16:33:02 +0000168<li>Removed some unused "#include <unistd.h>" that were causing problems
169 for VC++.</li>
drhf57b3392001-10-08 13:22:32 +0000170<li>Fixed <b>sqlite.h</b> so that it is usable from C++</li>
drh382c0242001-10-06 16:33:02 +0000171<li>Added the FULL_COLUMN_NAMES pragma. When set to "ON", the names of
172 columns are reported back as TABLE.COLUMN instead of just COLUMN.</li>
drhad75e982001-10-09 04:19:46 +0000173<li>Added the TABLE_INFO() and INDEX_INFO() pragmas to help support the

182 newlines anywhere in the data. This is an old bug that was carried
183 forward from version 1.0. To fix it, the ".dump" output no longer
184 uses the COPY command. It instead generates INSERT statements.</li>
185<li>Extend the expression syntax to support "expr NOT NULL" (with a
186 space between the "NOT" and the "NULL") in addition to "expr NOTNULL"
187 (with no space).</li>

209 bumping the major version number.</li>
