SQL Anywhere uses the SET statement to assign values to variables in a procedure. In Transact-SQL, values are assigned using either the SELECT statement with an empty table-list, or the SET statement. The following simple procedure illustrates how the Transact-SQL syntax works:

CREATE PROCEDURE multiply
               @mult1 int,
               @mult2 int,
               @result int output
AS
SELECT @result = @mult1 * @mult2;

This procedure can be called as follows:

CREATE VARIABLE @product int
go
EXECUTE multiply 5, 6, @product OUTPUT
go

The variable @product has a value of 30 after the procedure executes.
