This option turns off individual keywords. This option 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.
You cannot turn off the keywords set, option, and options. Whether a word is identified as a keyword is determined by the
following (in order of precedence):
It appears in the SQL Anywhere list of reserved words.
It has been turned on with the reserved_keywords option.
It has been turned off 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.
You can turn on individual keywords using the reserved_keywords option.
