Stored Procedures: Adding directives

Hi

Within a stored procedure, is there a way to add a directive which wraps around a piece of code, thereby that code is only visible if its directive is TRUE?

For example, in DEBUG mode, have code wrapped within a TRY/CATCH block:


Declare @deadline int
set @deadline = 0

BEGIN TRY 
    SELECT DaysToManufacture / @deadline
    from AdventureWorks.Production.Product
    WHERE ProductID = 921
END TRY
BEGIN CATCH
  EXECUTE usp_GetErrorInfo;
END CATCH;

And in PRODUCTION mode for performance reasons, have TRY/CATCH block not visible to the SQL engine. For example


Declare @deadline int
set @deadline = 0

SELECT DaysToManufacture / @deadline
from AdventureWorks.Production.Product
WHERE ProductID = 921
 
SELECT usp_GetErrorInfo;

Ideas?

Thanks

Jeff in Seattle

There isn't an easy way to do it. You'd have to have a table that specified what environment it was and then check with an IF statement to determine what to do.

But why do you think that the TRY/CATCH is a performance problem?
