SQL LOGOUT
| SQL LOGOUT | ||||||||
| Does not require any parameters | ||||||||
The SQL LOGOUT command closes the connection with an ODBC source that is open in the current process (if applicable). If there is no ODBC connection open, the command does nothing.
If the logout is performed properly, the system variable OK is set to 1; otherwise, it is set to 0. You can intercept this error with an error-handling method installed by the ON ERR CALL command.
