Question

SELECT col1,
       col2,
       col3,

EXEC GetAIntFromStoredProc(T.col1) AS col4
     FROM Tbl AS T
     WHERE (col2 = @parm) 

How to write this SQL query in SQL Server 2008?

Answer 1

Thanks @twoleggedhorse.

Here is the solution.

1. First we created a function

   CREATE FUNCTION GetAIntFromStoredProc(@parm Nvarchar(50)) RETURNS INTEGER
   
   AS
   BEGIN
      DECLARE @id INTEGER
   
      set @id= (select TOP(1) id From tbl where col=@parm)
   
      RETURN @id
   END
   

2. then we do the select query

   Select col1, col2, col3,
   GetAIntFromStoredProc(T.col1) As col4
   From Tbl as T
   Where col2=@parm
