Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

If you haven't already done so, run the stored procedure in the above folder to generate a database of training courses and delegates.

This exercise will create a procedure to allow you to move a person to a different organisation.  Your procedure will begin in a similar way to this:

SQL exercise - Error-handling (image 1)

The two arguments are the person to move, and the organisation to move them to

Create a log table to hold a record of every successful move:

SQL exercise - Error-handling (image 2)

Create 2 columns as shown here - iniitally your table will be empty

Write your stored procedure so that it:

  • Begins a transaction
  • Inserts a record in the log table recording that a person has been moved
  • Runs an UPDATE statement to change the person's OrgId column value
  • Commits the transaction if this doesn't generate an error, or rolls it back otherwise

Try testing your stored procedure - here are 3 suggestions to try:

Existing constraints will ensure that you can only move someone to a company which already exists

Optionally, save the code to generate your stored procedure as Log person moves.sql, then close it down.
