Exercise

Using error functions

For every month, you want to know the total amount of money you earned in your bike store. Instead of reviewing every order line, you thought it would be better to prepare a script that computes it and displays the results.

While writing the script, you made a mistake. As you can see, the operation 'Total: ' + SUM(price * quantity) AS total is missing a cast conversion, causing an error.

How can we catch this error? Show the error number, severity, state, line, and message.

Instructions

100 XP
  • Surround the operation with a TRY block.
  • Surround the functions with a CATCH block.
  • Select the error information.
