Alasql Options

AlaSQL Options

You can find all AlaSQL options in thealasql.options variable. The options are global for all databases - also if you create them withnew.

You can change these options directly from #" alasql.options.autocommit = true;">

alasql.options.autocommit=true;

or from SQL with theSET statement:

SET AUTOCOMMIT OFF;SET MODIFIER="RECORDSET";

Setting them via theSET statement is the only option when running from the console or if you run as a webworker and want to change options during executions.
