How Can I Call a Stored Procedure for Each Row in a Table Without Cursors?

Calling a Stored Procedure for Each Row Without a Cursor

If you need to invoke a stored procedure for every row in a table, but wish to avoid using a cursor, you can utilize a set-based approach. Here's a code snippet to guide you:

-- Declare & init (2008 syntax)
DECLARE @CustomerID INT = 0

-- Iterate over all customers
WHILE (1 = 1) 
BEGIN  

  -- Get next customerId
  SELECT TOP 1 @CustomerID = CustomerID
  FROM Sales.Customer
  WHERE CustomerID > @CustomerId 
  ORDER BY CustomerID

  -- Exit loop if no more customers
  IF @@ROWCOUNT = 0 BREAK;

  -- call your sproc
  EXEC dbo.YOURSPROC @CustomerId

END

This code iterates over a table, retrieves the next customer's ID, and invokes the stored procedure YOURSPROC with the ID as the parameter. It continues this loop until there are no more customers to process.
