along with our query i want it to also do this that is if the customername is Mika (ie the name is only one word and it doesnot contain any ',' or ' ')Then it should update to FirstName.....

update TableName
set lastname 
    = case
         when CHARINDEX(',', customername) > 0 then
            SUBSTRING(customername, 1, CHARINDEX(',', customername) - 1) -- comma is delimiter
         when CHARINDEX(' ', customername) > 0 then
            SUBSTRING(customername, CHARINDEX(' ', customername) + 1, LEN(customername) - CHARINDEX(' ', customername) + 1) -- space is delimiter
         else
            TableName.LastName --<code> no delimitter so don't change lastname in the table</code>
      end,
   firstname 
   = case
        when CHARINDEX(',', customername) > 0 then
           SUBSTRING(customername, CHARINDEX(',', customername) + 1, LEN(customername) - CHARINDEX(',', customername) + 1) -- comma is delimiter

Without the order by clause the query is working.

I can't change system tables space settings

I can't look at the execution plan. The query tool we are using does not allow that

SELECT alias1.Result
FROM (SELECT (ColA - ColB) AS Result 
      FROM    Table) alias1
WHERE alias1.result > 0

I was just kind of hoping there was a way to store the value in a temp variable on a row by row basis

so thanks

WITH Results AS
(
    SELECT ColA - ColB [Result]
      FROM TABLE
)
SELECT *
  FROM Results 
 WHERE Result > 0

SELECT ColA - ColB [Result]
  INTO #temp
  FROM TABLE

SELECT *
  FROM #temp
 WHERE Result > 0

DROP TABLE #temp

DECLARE @temp TABLE (Result int)

INSERT @temp
SELECT ColA - ColB [Result]
  FROM TABLE

SELECT *
  FROM @temp
 WHERE Result > 0
