This exit program is called when Easycom is using the SQL interface for the first time in the job (between SQL initialization and actual SQL usage, like SQL query prepare)
If using pre-start jobs, it is called before the connection is made (SQL is initialized at this moment to reduce the connection delay), during the pre-start process; otherwise, it is called when the SQL for the first time (so it is never called if SQL is not used by the application).
This exit program can be used to check the environment at this point.
