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.

Create a query to list out for each event the category number that it belongs to:

Ukraine events

Apply a WHERE criteria to show only those events in country number 1 (Ukraine).

 

This is harder than it looks!  You'll need to use the + symbol to join the following bits of text together:

  • The event name
  • An opening parenthesis, followed by the word category
  • The category number (but you'll need to cast this as a string of text)
  • The closing parenthesis

The syntax of the CAST function is:

CAST ( Something AS DataType)

When you've got this working, save this query as Events by category, and close it down.

we could use CONCAT function as well:- thanks :)

SELECT CONCAT(EventName,' ', '(', 'category ', CategoryID, ')'), EventDate
FROM tblEvent
WHERE CountryID = 1;
