Hi Thank you for reading my post is there any way that we can retrieve value of PK for a row in tables ? for example i have a table which its PK is composed of two field and now i want to store PK value for later use ( later use : I should delete some rows that i previusly stored their PK values) in one numeric field .
i should say that all PK are numeric as their used fields are numeric.
