TSQL_VARIABLES Option [TSQL]Locate this document in the navigation structure

Controls whether the @ sign can be used as a prefix for Embedded SQL host variable names.

Allowed Values

ON, OFF

Default

OFF

Scope

Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. 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

When TSQL_VARIABLES is set to ON, you can use the @ sign instead of the colon as a prefix for host variable names in Embedded SQL. This is implemented primarily for the Open Server Gateway.
