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 the world's leading websites.
Our task is to customise the standard (n row(s) affected) SQL message which appears after running a query. To start this, first create a simple SELECT statement to list out all of the columns and rows in the tblWebsite table:
This will list out 122 rows
When you run this query, it should produce the following message:
Your task is to replace this with a customised message
Add the following line of code (as always, no need to bother with the comment) to your stored procedure:
This will suppress the row count message above
Now amend your stored procedure so that it summarises the rows affected as follows (using the hint below):
The new version looks similar, but it has a heading, and the wording is subtly different
To do this, you'll need to declare a variable and set it equal to @@rowcount - otherwise the PRINT statements will reset the row count, and you'll get the wrong answer!
When your stored procedure is working, optionally save the query which generates it as RowCountWebsites.sql, then close it down.
