Question

I have table with two columns:

ItemMaster (Item INT, Quantity INT)

If an item is already there, then I should update the Quantity. Otherwise, I have to insert a Record in this table.

Is this possible without Loop?

I’m using SQL Server 2005.

Answer 1

It can be done without a loop yes:

UPDATE table1
SET Quantity = Quantity + 1
WHERE Item = @itemID

IF @@ROWCOUNT = 0
    INSERT INTO table1 (Item, Quantity)
    VALUES (@itemID, 1)
