Allowed Values

0 – 20000

Default

1024 kilobytes

Scope

Option can be set at the database (PUBLIC) or user level. When set at the database level, the value becomes the default for any new user, but has no impact on existing users. When set at the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.

Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.

Remarks

FPL_EXPRESSION_MEMORY_KB controls the use of memory for the optimization of queries involving functional expressions against columns having enumerated storage. The option enables the DBA to constrain the memory used by this optimization and balance it with other SAP Sybase IQ memory requirements, such as caches. Setting this option to 0 switches off optimization.
