Alasql Options

AlaSQL Options

You can find all AlaSQL options in the alasql.options variable. The options are global for all databases - also if you create them with new.

You can change these options directly from JavaScript:

    alasql.options.autocommit = true;

or from SQL with the SET statement:

    SET AUTOCOMMIT OFF;
    SET MODIFIER = "RECORDSET";

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