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. This database contains a table of websites called tblWebsite, which has (among others) two columns called:
- WebsiteName (the name of the website); and
- DateOnline (the date it first went online)
Create a stored procedure called spSchedules which takes two parameters:
- From date for searching (if not passed in, this should take the default value 1st January 1990)
- To date for searching (if not passed in, this should take the default value 31st December 1999)
The stored procedure should then show all websites registered between the two dates passed.
Try testing your query out - here are some things to try:
A couple of examples to try - but feel free to use your own instead
Use your stored procedure to show that only one website went online in 1991. The name might look vaguely familiar ...
Optionally, save the query to generate this stored procedure as Websites reg between 2 dates.sql, then close it down.
