21<li>The parser's stack was overflowing on a very long UPDATE statement.
22 This is now fixed.</li>

33<li>Better labels on column names of the result.</li>
34}
35
drh2dfbbca2000-07-28 14:32:48 +000036chng {2000 July 28} {
37<li>Added the <b>sqlite_busy_handler()</b>
38 and <b>sqlite_busy_timeout()</b> interface.</li>
39}
40
drh74c360e2000-06-23 19:16:23 +000041chng {2000 June 23} {
42<li>Begin writing the <a href="vdbe.html">VDBE tutorial</a>.</li>
43}

drh1fd14a72000-06-21 14:00:39 +000045chng {2000 June 21} {
46<li>Clean up comments and variable names. Changes to documentation.
47 No functional changes to the code.</li>
48}

drh6206d502000-06-19 19:09:08 +000050chng {2000 June 19} {
drh7ed19902000-06-19 19:10:28 +000051<li>Column names in UPDATE statements were case sensitive.
52 This mistake has now been fixed.</li>
drh6206d502000-06-19 19:09:08 +000053}
54
drh00400772000-06-16 20:51:26 +000055chng {2000 June 16} {
56<li>Added the concatenate string operator (||)</li>
57}

drh61fc2c62000-06-12 12:29:25 +000059chng {2000 June 12} {
drhe91cd0c2000-06-12 12:36:36 +000060<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
61 returns the number of database "Fetch" operations that have occurred.
62 This function is designed for use in test scripts to verify that
63 queries are efficient and appropriately optimized. Fcnt() has no other
64 useful purpose, as far as I know.</li>
65<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +000066 The new tests did not uncover any new problems.</li>
drh6de4f4c2000-06-12 12:20:48 +000067}
68
drhdcc7c742000-06-09 03:51:26 +000069chng {2000 June 8} {
70<li>Added lots of new test cases</li>
71<li>Fix a few bugs discovered while adding test cases</li>
72<li>Begin adding lots of new documentation</li>
73}
74
drh49c87802000-06-06 18:24:42 +000075chng {2000 June 6} {
drh37f0b252000-06-09 03:52:04 +000076<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,
drhf5005772000-06-06 22:19:00 +000077<b>INTERSECT</b>, and <b>EXCEPT</b></li>
drh49c87802000-06-06 18:24:42 +000078<li>Added support for using <b>(SELECT ...)</b> within expressions</li>
79<li>Added support for <b>IN</b> and <b>BETWEEN</b> operators</li>
80<li>Added support for <b>GROUP BY</b> and <b>HAVING</b></li>
81<li>NULL values are now reported ot the callback as a NULL pointer
82 rather than an empty string.</li>
83}
84
drh32aa77e2000-06-03 19:28:48 +000085chng {2000 June 3} {
86<li>Added support for default values on columns of a table.</li>
87<li>Improved test coverage. Fixed a few obscure bugs found by the
88improved tests.</li>
89}
90
drhbed86902000-06-02 13:27:59 +000091chng {2000 June 2} {
92<li>All database files to be modified by an UPDATE, INSERT or DELETE are
93now locked before any changes are made to any files.
94This makes it safe (I think) to access
95the same database simultaneously from multiple processes.</li>
96<li>The code appears stable so we are now calling it "beta".</li>
97}
98
99chng {2000 June 1} {
100<li>Better support for file locking so that two or more processes
101(or threads)
102can access the same database simultaneously. More work needed in
103this area, though.</li>
104}
105
drh7203e282000-05-31 15:35:42 +0000106chng {2000 May 31} {
drhbf66fff2000-05-31 15:43:25 +0000107<li>Added support for aggregate functions (Ex: <b>COUNT(*)</b>, <b>MIN(...)</b>)
drhcce7d172000-05-31 15:34:51 +0000108to the SELECT statement.</li>
drh56d48ad2000-05-31 21:06:30 +0000109<li>Added support for <B>SELECT DISTINCT ...</B></li>

113<li>Added the <b>LIKE</b> operator.</li>
114<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
115but it uses Unix shell globbing wildcards instead of the '%'
116and '_' wildcards of SQL.</li>
117<li>Added the <B>COPY</b> command patterned after
118<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
119can now read the output of the <b>pg_dump</b> database dump utility
120of PostgreSQL.</li>
121<li>Added a <B>VACUUM</B> command that that calls the
122<b>gdbm_reorganize()</b> function on the underlying database
123files.</li>
124<li>And many, many bug fixes...</li>
125}
