I need to search a Float variable named 'Diopter' and look for a decimal point. If the decimal point does not exist I need to append a '.0' Here is a code snippet
Begin

    SELECT TOP 1
	WaferID,
	TrayID,
	    CASE UPPER(FixedOrPower)
		WHEN 'POWER' THEN RTRIM(STR(Diopter)) + 'D'
		ELSE '#' + FixedPinNumber
	    END AS DioptorOrFixed,
	    RTRIM(REPLACE(CONVERT(VARCHAR(8), ProcessDateTime, 2),'.','')AS          ProcessDate,
	    RTRIM(CONVERT(VARCHAR(5), ProcessDateTime, 108)) AS ProcessTime,
	    EquipmentID AS EquipmentNumber,
	    CavityNumber,
	    PolyCNumber1,
	    PolyCNumber2,
	    PinSerialNumber,
	    HolderID,
	    OperatorEmployeeNumber AS OperatorID,
	    SetupTechEmployeeNumber + '     .' AS SetupTechID, 
            PinRadius1,
	    PinRadius2,
	    WaferRadius1,
	    WaferRadius2
	FROM dbo.TBL_ProcessedWaferTray
	WHERE TrayID = @TrayID
	ORDER BY TrayID, ProcessDateTime DESC
end

Look at the following and see if it helps.

SQL

DECLARE @d AS FLOAT = 72
SELECT
    @d,
    CAST(@d AS VARCHAR(10)) AS StingVal,
    CHARINDEX('.', CAST(@d AS VARCHAR(10))) AS Position,
    CASE
        WHEN CHARINDEX('.', CAST(@d AS VARCHAR(10))) = 0
            THEN CAST(@d AS VARCHAR(10)) + '.0D'
            ELSE CAST(@d AS VARCHAR(10)) + 'D'
    END AS DesiredVal

The code works in 2008 but should also work in 2005

That makes no sense at all.
Float values do not have a decimal point - they only get one when you convert them to a string.
If what you mean is that if a string does not contain a decimal point then add ".0", then the code you need is similar to:

SQL

IF CHARINDEX('.', @DIOPTER) <= 0
   BEGIN
   set @DIOPTER = RTRIM(@DIOPTER) + '.0'
   END

I'm no sql expert, but I think this might work (or at least set you on the right track):

SQL

CASE UPPER(FixedOrPower)
    WHEN 'POWER' THEN CASE CHARINDEX('.', RTRIM(STR(Diopter))
                          WHEN 0 THEN RTRIM(STR(Diopter)) + '.0D'
                          ELSE RTRIM(STR(Diopter)) + 'D'
                      END
    ELSE '#' + FixedPinNumber
END AS DioptorOrFixed

Sorry JSOP, I didn't realize you had responded - I was busy testing it since I always but the parameters in the wrong order in CHARINDEX...:laugh:

No worries. I honestly expected to see your answer before I got mine posted, because I had to google charindex. :)
