I need to branch my T-SQL stored procedure (MS SQL 2008) control flow to a number of directions:
CREATE PROCEDURE [fooBar]
@inputParam INT
AS
BEGIN
IF @inputParam = 1
BEGIN
...
END
ELSE IF @inputParam = 3
BEGIN
...
END
ELSE IF @inputParam = 3
BEGIN
...
END
END
Is there any other ways? For example, in C# I shoud use switch-case block.
IF…ELSE… is pretty much what we’ve got in T-SQL. There is nothing like structured programming’s CASE statement. If you have an extended set of …ELSE IF…s to deal with, be sure to include BEGIN…END for each block to keep things clear, and always remember, consistent indentation is your friend!
