105<li>The file format for indices was changed slightly in order to work
106 around an inefficiency that can sometimes come up with GDBM when
107 there are large indices having many entries with the same key.

drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]151<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
152 returns the number of database "Fetch" operations that have occurred.
153 This function is designed for use in test scripts to verify that
154 queries are efficient and appropriately optimized. Fcnt() has no other
155 useful purpose, as far as I know.</li>
156<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000[diff] [blame]157 The new tests did not uncover any new problems.</li>

drh37f0b252000-06-09 03:52:04 +0000[diff] [blame]167<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,
drhf5005772000-06-06 22:19:00 +0000[diff] [blame]168<b>INTERSECT</b>, and <b>EXCEPT</b></li>

drhbed86902000-06-02 13:27:59 +0000[diff] [blame]182chng {2000 June 2} {
183<li>All database files to be modified by an UPDATE, INSERT or DELETE are
184now locked before any changes are made to any files.
185This makes it safe (I think) to access
186the same database simultaneously from multiple processes.</li>
187<li>The code appears stable so we are now calling it "beta".</li>
188}
189
190chng {2000 June 1} {
191<li>Better support for file locking so that two or more processes
192(or threads)
193can access the same database simultaneously. More work needed in
194this area, though.</li>
195}

204<li>Added the <b>LIKE</b> operator.</li>
205<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
206but it uses Unix shell globbing wildcards instead of the '%'
207and '_' wildcards of SQL.</li>
208<li>Added the <B>COPY</b> command patterned after
209<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
210can now read the output of the <b>pg_dump</b> database dump utility
211of PostgreSQL.</li>
212<li>Added a <B>VACUUM</B> command that that calls the
213<b>gdbm_reorganize()</b> function on the underlying database
214files.</li>
215<li>And many, many bug fixes...</li>
