Hi there,

I have written the following test SQL statement in query analyser:

UPDATE PremAddTest1 SET PremAddTest1.DatabaseRef = PremAddTest2.DatabaseRef FROM PremAddTest2
WHERE PremAddTest1.Parish = PremAddTest2.Parish AND PremAddTest1.Site = PremAddTest2.Site AND PremAddTest1.Parish = PremAddTest2.Premise;

All I need to do is perform this statement on every row in the PremAddTest1 table, but I'm not sure of the syntax for this.

Something like:


FOR each row in PremAddTest1

run update statement

Move to next row

Can anyone help?

Thanks

That statement will update every row in the table.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.
