My values vary from 20 to 20000, but have no decimal. I can cast as dec, but I don't need to add on anything - just insert a decimal 2 positions to the left......beginning from the right.
ie: 6288 convert to 62.88
Thanks

That works, but unfortunately the data is for accounting - So rounding is not an option.

Any other ideas?

How does the system deal with VAT?

Is the datatype really varchar? If it is, then use REVERSE then STUFF then REVERSE.

Not sure I understand how dividing by 100 is rounding. All that does is move the decimal place two places to the left.

--==First, lets knock up some sample data==--

DECLARE @TABLE AS TABLE(number VARCHAR(50))

INSERT INTO @TABLE (number)

SELECT TOP 250000

CONVERT(VARCHAR(50),FLOOR(RAND(CHECKSUM(NEWID())) * 20000)+1)

FROM sys.all_columns ac1

CROSS JOIN sys.all_columns ac2

--==Query==-

SELECT number AS original,

CONVERT(MONEY,number) / 100 AS option_1,

CASE WHEN LEN(number)-2 > 0

THEN LEFT(number,LEN(number)-2)+'.'+RIGHT(number,2)

ELSE LEFT(number,2)+'.'+RIGHT(number,2) END AS option_2

FROM @TABLE

To use the div/100, I must need to insert a decimal first - because it drops off the change.

,TRANS_AMOUNT/100 as TransAmt

ie: 6288 becomes 62

ahh gotcha it is doing int division. Since you original values do not have a decimal place they will be interpreted as an int. You need to force it use decimal division like this.

TRANS_AMOUNT/100. as TransAmt

Notice I just added the decimal after the 100 which is the same as 100.0

This worked, but your suggestion is cleaner.

,CAST(TRANS_AMOUNT AS DEC(12,2))/100 AS TransAmt

Thank you all!
