Create a stored procedure to list out the EventName, EventDate and Country fields (to do this you will need to join the tblEvent and tblCountry tables together using CountryID):

No filter #NotThatKindOfFilter

The first five rows that you might see.

Once you have done this, add a parameter to your stored procedure that will take in the country name of interest and use this to filter the rows displayed:


(@ParaName ParaDatatype)


Try passing in different countries or parts of country names to change the number of events returned. Concatenating % or _ onto the parameter will return more results.

Parameters filtering procedures

Using the letter S should return 94 results. Try the first letter of your name!

Optionally, save your query as Country events.sql, then close it down.
