Variable for Column Alias

CODE

DECLARE @StartDate DATETIME         SET @StartDate = '2009/01/01 00:00:00'
DECLARE @EndDate DATETIME           SET @EndDate   = '2009/05/20 23:59:59'
DECLARE @APPLICATION VARCHAR(3)        SET @APPLICATION = 'PRV'
DECLARE @ELEMENT1name VARCHAR(100)     SET @ELEMENT1name = 'MemberID'
DECLARE @ELEMENT1 VARCHAR(100)         SET @ELEMENT1 = 'PatID_ValidIDPrompt'
DECLARE @ELEMENT2name VARCHAR(100)     SET @ELEMENT2name = 'Total_Calls'
DECLARE @ELEMENT2 VARCHAR(100)         SET @ELEMENT2 = 'PatID_Silencer'

SELECT
  apname as @application,
  table2.elemname as @ELEMENT1name,
  table1.elemname as @ELEMENT2name,
  @ELEMENT1 / @ELEMENT2 as 'percentage'
FROM
...

This is a simplified snipit of the code I am trying to make more dynamic.

If you want to format your columns certain way (make the names of the fields to match your variables), then you should construct the whole query as one string and execute it using execute statement.

I am not certain on what you are saying... I want the column names to be resembling the field variables, but not as technical.

Can you share a simple example of what you are describing?
