how is the simplest way to test if some column exists in DB2?
i am just trying to run a script that add a column. I don't want a procedure.
It is necessery to use Begin End or create a procedure?

```
IF (NOT EXISTS(
SELECT * FROM P1ADM549.T549RMOP WHERE VR_PGO ='VR_PGO' AND COLNAME = 'VR_PGO'))
THEN
    EXECUTE something...
END

```
