Question

This multiple SELECT QUERY runs consecutively. I need one report with multiple columns for [GBPMID] and [EURMID].

Query 1

SELECT
    (([askPrice] - [bidPrice]) / 2) + [bidPrice] AS [EURMID]
    FROM TicksForex 
        WHERE [Symbol] = 'EUR/USD' 
        AND [Time] >= CONVERT(datetime, '6/6/2011 12:00 AM')

Query 2

SELECT
     [Time]
    ,[askPrice]
    ,[bidPrice]
    ,(([askPrice] - [bidPrice]) / 2) + [bidPrice] AS [GBPMID]
    FROM TicksForex 
        WHERE [Symbol] = 'GBP/USD'  
        AND [Time] >= CONVERT(datetime, '6/6/2011 12:00 AM')

@Pranay & @Magnus – MY APOLOGIES! My Data tables do not share the same TIME Values… which was a surprise to me.. this is why the records do not line up.. so sorry!! I will run this as @Pranay describes below…

Forget it! It normalized the data (date) so they all shared the same date – ie.. updated prices at the same time.. and it still does not work!!

Make use of Case...when will resolve you issue easily

SELECT
     [Time]
    ,[askPrice]
    ,[bidPrice],

  ( CASE WHEN Symbol = 
          'GBP/USD' THEN ((([askPrice] - [bidPrice]) / 2) + [bidPrice])
         ELSE 0
      END) AS [GBPMID],
  ( CASE WHEN Symbol =
           'EUR/USD' THEN ((([askPrice] - [bidPrice]) / 2) + [bidPrice])
         ELSE 0
      END) AS [EURMID]

    FROM TicksForex 
        WHERE ([Symbol] = 'GBP/USD'  or [Symbol] = 'EUR/USD' )
        AND [Time] >= CONVERT(datetime, '6/6/2011 12:00 AM')
