- update to 3.35.0:
* Added built-in SQL math functions().
(Requires the -DSQLITE_ENABLE_MATH_FUNCTIONS compile-time option.)
* Added support for ALTER TABLE DROP COLUMN.
* Generalize UPSERT:
* Allow multiple ON CONFLICT clauses that are evaluated in order,
* The final ON CONFLICT clause may omit the conflict target and yet still use DO UPDATE.
* Add support for the RETURNING clause on DELETE, INSERT, and UPDATE statements.
* Use less memory when running VACUUM on databases containing very large TEXT
or BLOB values. It is no longer necessary to hold the entire TEXT or BLOB
in memory all at once.
* Add support for the MATERIALIZED and NOT MATERIALIZED hints when specifying
common table expressions. The default behavior was formerly NOT
MATERIALIZED, but is now changed to MATERIALIZED for CTEs that are used
more than once.
* The SQLITE_DBCONFIG_ENABLE_TRIGGER and SQLITE_DBCONFIG_ENABLE_VIEW settings
are modified so that they only control triggers and views in the main
database schema or in attached database schemas and not in the TEMP schema.
TEMP triggers and views are always allowed.
* Query planner/optimizer improvements
* Enhance the ".stats" command to accept new arguments "stmt" and "vmstep",
causing prepare statement statistics and only the virtual-machine step
count to be shown, respectively.
* Add the ".filectrl data_version" command.
* Enhance the ".once" and ".output" commands so that if the destination
argument begins with "|" (indicating that output is redirected into a pipe)
then the argument does not need to be quoted.
* Fix a bug in the IN-operator optimization of version 3.33.0 that can cause
an incorrect answer.
* Fix incorrect answers from the LIKE operator if the pattern ends with "%"
