Question

Here is my SQL query

Declare @Type varchar

select  
  if
    (tn.notification_type=1)
  begin
    set @Type= 'WORK FLOW'
    print  'status  '+ CAST(@type AS nvarchar(58))  
  end
from tbl_Notification tn

here I am getting problem to include a condition based on a table column value

E.g. I have values 1 and 2 and 3

when I execute I am getting the error.

Msg 156, Level 15, State 1, Line 3
Incorrect syntax near the keyword ‘if’.
Msg 156, Level 15, State 1, Line 9
Incorrect syntax near the keyword ‘from’.

Answer 1

To elaborate on Namphibian’s answer, which is accurate:

SELECT
      @Type = (CASE tn.Notification_Type 
                   WHEN 1 THEN 'WORK FLOW' 
                   ELSE 'SOMETHING ELSE' 
                END)
FROM tbl_Notification tn

You also won’t be able to do the print in the SQL query like that, you’d have to do it afterwards or in some sort of looping situation.
