truncation of value passed into the stored procedure

I want my stored procedure to throw an error if the value passed into the parameter is > the length of how the variable is declared rather then doing what it is doing now and truncating the passed value. How?

Well, you will need to declare the parameter as large as the biggest number of characters.

Then inside the procedure have your procedural declaratives to load and check

CREATE PROCEDURE usp_my_test_procedure (@Parameter1 varchar(500) ) 
DECLARE @Name       varchar(50)

IF LEN(@Parameter1) between 1 and 50
   SELECT ERROR = '@Parameter1 is wrong size '+cast(LEN(@Parameter1) as varchar(10))

SELECT GOOD = 'Good parameter ' + @name


-- now test

exec usp_my_test_procedure @Parameter1 = 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa'
exec usp_my_test_procedure @Parameter1 = 'bbb'

Is there something built into SQL server that would make if error rather then truncate?
Mark WillsTopic AdvisorCommented:
Not that I know of.

It can also happen with variables. These are about the only two places where  ANSI_WARNINGS  are not honoured.

There used to be a connect ticket (now collaborate) in Microsoft, but was always 'not changing'

edit : "Not that I know of." really means "I know there isnt"
