How do I catch a stored procedure error?

Where is a stored procedure saved?

How to return error message in stored procedure?

What happens if you do not specify output in a procedure?
If you specify OUTPUT for a parameter when you call a procedure and that parameter is not defined by using OUTPUT in the procedure definition, you get an error message. However, you can execute a procedure with output parameters and not specify OUTPUT when executing the procedure.
Can a procedure be called from the database?
Because OUTPUT parameters must be bound before an application can execute a procedure, procedures with cursor OUTPUT parameters cannot be called from the database APIs. These procedures can be called from Transact-SQL batches, procedures, or triggers only when the cursor OUTPUT variable is assigned to a Transact-SQL local cursor variable.
