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:

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:
When you've got this working, save this query as Events by category, and close it down.
SELECT
CONCAT(EventName , '(', 'Catgeory',' ', CategoryID , ')') AS [Event(Category)] ,
EventDate
FROMtblEvent
WHERE CountryID = 1
My Solution:
Select EventName +' (category ' + Cast(CategoryID as nvarchar(10)) + ')' as [Event (category)], EventDate from tblEvent
Where CountryID = 1
SELECT Concat(EventName, ' (' , CategoryID , ') ')
,EventDate
FROM tblEvent
WHERE CountryID = 1
SELECT EventName + ' (' + Convert(Varchar(2),CategoryID) + ')'
,EventDate
FROM tblEvent
WHERE CountryID = 1
SELECT EventName + ' (' + Cast(CategoryID as varchar(2)) + ')'
,EventDate
FROM tblEvent
WHERE CountryID = 1
we could use CONCAT function as well:- thanks :)
SELECT CONCAT(EventName,' ', '(', 'category ', CategoryID, ')'), EventDate
FROM tblEvent
WHERE CountryID = 1;
