I have a Problem with RDBMSPI.

I change the data of a string TAG in a Analyse of PI-AF.

Now i try to write the value and timestamp of this tag via RDBMSPI by

/SQL="UPDATE CAS_TEILANLAGE SET Bemerkung = ? , Bearbeitungsdatum = ?  WHERE TEILANLAGE_ID = 1534 ;" P1=VL  P2=TS

Sometimes i find changed data in table, sometimes nothing changed in table when tag is changed.

When I restarted Interface, data will be changed in table.

For tag devinition look at screnshots


scan Interval  is 1 Minute


Thanks for help
