Is it possible to execute a stored procedure over a set without using a cursor?

Question

I would like to execute a stored procedure over each row in a set without using a cursor with something like this:

SELECT EXEC dbo.Sproc @Param1 = Table1.i

Answer 1

Yes. If you have a column you can use within the table to mark the ones processed, you can use WHILE EXISTS:

DECLARE @Id int
WHILE EXISTS(SELECT * FROM Table1 WHERE Processed='N')
BEGIN
 SELECT Top 1 @Id = id from Table1 WHERE Procesed='N'
 EXEC dbo.Sproc @Id
 UPDATE Table1 SET Processed = 'Y' WHERE Id = @Id
END

Alternately, dump the ids into a temp table or table variable and delete when finished:

DECLARE @HoldTable table (Id int PRIMARY KEY)
DECLARE @Id int
INSERT INTO @HoldTable SELECT Id FROM Table1
WHILE EXISTS(SELECT * FROM @HoldTable)
BEGIN
 SELECT @Id = id from @HoldTable
 EXEC dbo.Sproc @Id
 DELETE FROM @HoldTable where Id = @Id
END
