Everytime I want to test an SQL code with parameters, I have to DECLARE them so that the code can run with the '@' character.
Otherwise I have to rename the '@' chars to ':' colon chars to be able to run the code natively.
So please allow TOAD for SQL Server to run native SQL code with '@' parameters directly and still prompt user for the values, as if running the code with colon char parameters.
ie:
SELECT StudentName FROM tblStudents WHERE StudentID = @StudentID
