How to concatenate in SQL Server

Question

My database doesn\'t have a specific column so I created a column in my query by switch. What I need is to concatenate this column with another column in the database:

Answer 1

You just need to try + operator or CONCAT function

1. + for all SQL Server versions

   DurationType = ' + 'some text'
   

2. CONCAT for SQL Server 2012 +

   CONCAT('DurationType = ', 'some text')
   

Your query should be something like this

SELECT certificateDuration
       ,'DurationType = ' + 
       CASE certificateDurationType
           WHEN 0 THEN 'Day'
           WHEN 1 THEN 'Month'
           WHEN 2 THEN 'Year'
       END
