48 circumstance: a query on an indexed table containing a WHERE clause with
49 an IN operator that had a subquery on its right-hand side.</li>

59 databases for which it lacks write permission. (It used to
60 refuse all access if it could not write.)</li>

78<li>File format version number was being stored in sqlite_master.tcl

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

116 No functional changes to the code.</li>

drh7ed19902000-06-19 19:10:28 +0000[diff] [blame]120<li>Column names in UPDATE statements were case sensitive.

drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]129<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
130 returns the number of database "Fetch" operations that have occurred.
131 This function is designed for use in test scripts to verify that
132 queries are efficient and appropriately optimized. Fcnt() has no other
133 useful purpose, as far as I know.</li>
134<li>Added a bunch more tests that take advantage of the new fcnt() function.
drh61fc2c62000-06-12 12:29:25 +0000[diff] [blame]135 The new tests did not uncover any new problems.</li>

drh37f0b252000-06-09 03:52:04 +0000[diff] [blame]145<li>Added compound select operators: <B>UNION</b>, <b>UNION ALL</B>,
drhf5005772000-06-06 22:19:00 +0000[diff] [blame]146<b>INTERSECT</b>, and <b>EXCEPT</b></li>

drhbed86902000-06-02 13:27:59 +0000[diff] [blame]160chng {2000 June 2} {
161<li>All database files to be modified by an UPDATE, INSERT or DELETE are
162now locked before any changes are made to any files.
163This makes it safe (I think) to access
164the same database simultaneously from multiple processes.</li>
165<li>The code appears stable so we are now calling it "beta".</li>
166}
167
168chng {2000 June 1} {
169<li>Better support for file locking so that two or more processes
170(or threads)
171can access the same database simultaneously. More work needed in
172this area, though.</li>
173}

drhdce2cbe2000-05-31 02:27:49 +0000[diff] [blame]181chng {2000 May 30} {
182<li>Added the <b>LIKE</b> operator.</li>
183<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
184but it uses Unix shell globbing wildcards instead of the '%'
185and '_' wildcards of SQL.</li>
186<li>Added the <B>COPY</b> command patterned after
187<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
188can now read the output of the <b>pg_dump</b> database dump utility
189of PostgreSQL.</li>
190<li>Added a <B>VACUUM</B> command that that calls the
191<b>gdbm_reorganize()</b> function on the underlying database
192files.</li>
193<li>And many, many bug fixes...</li>
