drhe91cd0c2000-06-12 12:36:36 +0000[diff] [blame]174<li>Added the fcnt() function to the SQL interpreter. The fcnt() function
175 returns the number of database "Fetch" operations that have occurred.
176 This function is designed for use in test scripts to verify that
177 queries are efficient and appropriately optimized. Fcnt() has no other
178 useful purpose, as far as I know.</li>
179<li>Added a bunch more tests that take advantage of the new fcnt() function.

206<li>All database files to be modified by an UPDATE, INSERT or DELETE are
207now locked before any changes are made to any files.
208This makes it safe (I think) to access
209the same database simultaneously from multiple processes.</li>
210<li>The code appears stable so we are now calling it "beta".</li>
211}

213chng {2000 June 1} {

227<li>Added the <b>LIKE</b> operator.</li>
228<li>Added a <b>GLOB</b> operator: similar to <B>LIKE</B>
229but it uses Unix shell globbing wildcards instead of the '%'
230and '_' wildcards of SQL.</li>
231<li>Added the <B>COPY</b> command patterned after
232<a href="http://www.postgresql.org/">PostgreSQL</a> so that SQLite
233can now read the output of the <b>pg_dump</b> database dump utility
234of PostgreSQL.</li>
235<li>Added a <B>VACUUM</B> command that that calls the
236<b>gdbm_reorganize()</b> function on the underlying database
237files.</li>
