" } chng {2000 Aug 9} {
  • Treat carriage returns as white space.
  • } chng {2000 Aug 8} {
  • Added pattern matching to the ".table" command in the "sqlite" command shell.
  • } chng {2000 Aug 4} {
  • Documentation updates
  • Added "busy" and "timeout" methods to the Tcl interface
  • } chng {2000 Aug 3} {
  • File format version number was being stored in sqlite_master.tcl multiple times. This was harmless, but unnecessary. It is now fixed.
  • } chng {2000 Aug 2} {
  • The file format for indices was changed slightly in order to work around an inefficiency that can sometimes come up with GDBM when there are large indices having many entries with the same key. ** Incompatible Change **
  • } chng {2000 Aug 1} {
  • The parser's stack was overflowing on a very long UPDATE statement. This is now fixed.
  • } chng {2000 July 31} {
  • Finish the VDBE tutorial.
  • Added documentation on compiling to WindowsNT.
  • Fix a configuration program for WindowsNT.
  • Fix a configuration problem for HPUX.
  • } chng {2000 July 29} {
  • Better labels on column names of the result.
  • } chng {2000 July 28} {
  • Added the sqlite_busy_handler() and sqlite_busy_timeout() interface.
  • } chng {2000 June 23} {
  • Begin writing the VDBE tutorial.
  • } chng {2000 June 21} {
  • Clean up comments and variable names. Changes to documentation. No functional changes to the code.
  • } chng {2000 June 19} {
  • Column names in UPDATE statements were case sensitive. This mistake has now been fixed.
  • } chng {2000 June 16} {
  • Added the concatenate string operator (||)
  • } chng {2000 June 12} {
  • Added the fcnt() function to the SQL interpreter. The fcnt() function returns the number of database "Fetch" operations that have occurred. This function is designed for use in test scripts to verify that queries are efficient and appropriately optimized. Fcnt() has no other useful purpose, as far as I know.
  • Added a bunch more tests that take advantage of the new fcnt() function. The new tests did not uncover any new problems.
  • } chng {2000 June 8} {
  • Added lots of new test cases
  • Fix a few bugs discovered while adding test cases
  • Begin adding lots of new documentation
  • } chng {2000 June 6} {
  • Added compound select operators: UNION, UNION ALL, INTERSECT, and EXCEPT
  • Added support for using (SELECT ...) within expressions
  • Added support for IN and BETWEEN operators
  • Added support for GROUP BY and HAVING
  • NULL values are now reported ot the callback as a NULL pointer rather than an empty string.
  • } chng {2000 June 3} {
  • Added support for default values on columns of a table.
  • Improved test coverage. Fixed a few obscure bugs found by the improved tests.
  • } chng {2000 June 2} {
  • All database files to be modified by an UPDATE, INSERT or DELETE are now locked before any changes are made to any files. This makes it safe (I think) to access the same database simultaneously from multiple processes.
  • The code appears stable so we are now calling it "beta".
  • } chng {2000 June 1} {
  • Better support for file locking so that two or more processes (or threads) can access the same database simultaneously. More work needed in this area, though.
  • } chng {2000 May 31} {
  • Added support for aggregate functions (Ex: COUNT(*), MIN(...)) to the SELECT statement.
  • Added support for SELECT DISTINCT ...
  • } chng {2000 May 30} {
  • Added the LIKE operator.
  • Added a GLOB operator: similar to LIKE but it uses Unix shell globbing wildcards instead of the '%' and '_' wildcards of SQL.
  • Added the COPY command patterned after PostgreSQL so that SQLite can now read the output of the pg_dump database dump utility of PostgreSQL.
  • Added a VACUUM command that that calls the gdbm_reorganize() function on the underlying database files.
  • And many, many bug fixes...
  • } chng {2000 May 29} {
  • Initial Public Release of Alpha code
  • } puts {
