non_keywords option [compatibility]

Turns off individual keywords, allowing their use as identifiers.

Allowed values

String

Default

Empty string

Remarks

This option turns off individual keywords. This provides a way of ensuring that applications created with older versions of the product are not broken by new keywords. If you have an identifier in your database that is now a keyword, you can either add double quotes around the identifier in all applications or scripts, or turn off the keyword using the non_keywords option.

The following statement prevents TRUNCATE and SYNCHRONIZE from being recognized as keywords:

SET OPTION non_keywords = 'TRUNCATE, SYNCHRONIZE';

Each new setting of this option replaces the previous setting. The following statement clears all previous settings.

SET OPTION non_keywords =;

A side-effect of this option is that SQL statements that use a turned off keyword cannot be used: they produce a syntax error.
