UPDATE with data at exec and CURRENT OF question

Hi,

after all my tries I ran into trouble with this statement:

UPDATE "Kontakte" set "Notiz" = ? WHERE CURRENT OF SQL_CUR0x1321f670

I see that my parameter has been passed. And the driver has build up
the query. But I do not understand, why
there is a syntax error near the 'OF' keyword.

Does PostgreSQL not support this syntax ?

Thanks, Lothar
