Deleting rows using stored procedure with parameter - stored-procedures

Question

I am using SQL Server 2008 R2 and I want to create a stored procedure that deletes from two tables using a paramater (id).
This is the stored procedure:
CREATE PROCEDURE [dbo].[sp_deleteDecision]
#ID int
AS
DELETE FROM [dbo].[tblDecisionInvolvement] as di
WHERE di.DecisionId = #ID
DELETE FROM [dbo].[tblDecision] as d
WHERE d.Id =#ID
GO
This is the error I get when I try to create it:
Msg 156, Level 15, State 1, Procedure sp_deleteDecision, Line 6
Incorrect syntax near the keyword 'as'.
Msg 156, Level 15, State 1, Procedure sp_deleteDecision, Line 8
Incorrect syntax near the keyword 'as'.
Note that changing the DELETE FROM to
SELECT * FROM
it works.
Is it even possible to delete something using parameters?

You aren't allowed to introduce an alias at that part of a DELETE statement - nor do you need one in this case:
USE ChessDb01
GO
CREATE PROCEDURE [dbo].[sp_deleteDecision]
#ID int
AS
DELETE FROM [dbo].[tblDecisionInvolvement]
WHERE DecisionId = #ID
DELETE FROM [dbo].[tblDecision]
WHERE Id =#ID
GO
For a more complex query, you might want to use an alias, but note that (confusingly), the DELETE will have two FROM clauses - and you can only introduce the alias in the second one:
DELETE FROM di
FROM [dbo].[tblDecisionInvolvement] di
inner join
AnotherTable tab
on
di.Column = tab.Column2
WHERE tab.Column99 = #Value
