Question 5: You need to create a stored procedure that meets the following requirements:*Produces a warning if the credit limit parameter is greater than 7,000
*Propagates all unexpected errors to the calling process
How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-
SQP segments to the correct locations. Each Transact-SQL segments may be used once, more than
once, or not at all. You may need to drag the split bar between panes or scroll to view content.
Correct Answer:
Explanation
Box 1: THROW 51000, 'Warning: Credit limit is over 7,000!",1
THROW raises an exception and transfers execution to a CATCH block of a TRY...CATCH construct in
SQL Server.
THROW syntax:
THROW [ { error_number | @local_variable },
{ message | @local_variable },
{ state | @local_variable } ]
[ ; ]
Box 2: RAISERROR (@ErrorMessage, 16,1)
RAISERROR generates an error message and initiates error processing for the session. RAISERROR can
either reference a user-defined message stored in the sys.messages catalog view or build a message
dynamically. The message is returned as a server error message to the calling application or to an
associated CATCH block of a TRY...CATCH construct. New applications should use THROW instead.
Severity levels from 0 through 18 can be specified by any user. Severity levels from 19 through 25 can
only be specified by members of the sysadmin fixed server role or users with ALTER TRACE
permissions. For severity levels from 19 through 25, the WITH LOG option is required.
On Severity level 16. Using THROW to raise an exception
The following example shows how to use the THROW statement to raise an exception.
Transact-SQL
THROW 51000, 'The record does not exist.', 1;
Here is the result set.
Msg 51000, Level 16, State 1, Line 1
The record does not exist.
Note: RAISERROR syntax:
RAISERROR ( { msg_id | msg_str | @local_variable }
{ ,severity ,state }
[ ,argument [ ,...n ] ] )
[ WITH option [ ,...n ] ]
Note: The ERROR_MESSAGE function returns the message text of the error that caused the CATCH
block of a TRY...CATCH construct to be run.
