drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]48<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
49 returns the number of database "Fetch" operations that have occurred.
50 This function is designed for use in test scripts to verify that
51 queries are efficient and appropriately optimized. Fcnt() has no other
52 useful purpose, as far as I know.</li>
53<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000[diff] [blame]54 The new tests did not uncover any new problems.</li>

drh37f0b252000-06-09 03:52:04 +0000[diff] [blame]64<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,
drhf5005772000-06-06 22:19:00 +0000[diff] [blame]65<b>INTERSECT</b>, and <b>EXCEPT</b></li>

70 rather than an empty string.</li>

75<li>Improved test coverage. Fixed a few obscure bugs found by the
76improved tests.</li>

drhbed86902000-06-02 13:27:59 +0000[diff] [blame]79chng {2000 June 2} {
80<li>All database files to be modified by an UPDATE, INSERT or DELETE are
81now locked before any changes are made to any files.
82This makes it safe (I think) to access
83the same database simultaneously from multiple processes.</li>
84<li>The code appears stable so we are now calling it "beta".</li>
85}
86
87chng {2000 June 1} {
88<li>Better support for file locking so that two or more processes
89(or threads)
90can access the same database simultaneously. More work needed in
91this area, though.</li>
92}

drhcce7d172000-05-31 15:34:51 +0000[diff] [blame]96to the SELECT statement.</li>

101<li>Added the <b>LIKE</b> operator.</li>
102<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
103but it uses Unix shell globbing wildcards instead of the '%'
104and '_' wildcards of SQL.</li>
105<li>Added the <B>COPY</b> command patterned after
106<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
107can now read the output of the <b>pg_dump</b> database dump utility
108of PostgreSQL.</li>
109<li>Added a <B>VACUUM</B> command that that calls the
110<b>gdbm_reorganize()</b> function on the underlying database
111files.</li>
112<li>And many, many bug fixes...</li>
