Ninja's_RGR'us SSC-Insane Group: General Forum Members Points: 20931 Visits: 9671 This should do the trick... 100% of the time : DECLARE @Val DECIMAL (11,8)SET @Val = 100.10300100SELECT REPLACE(RTRIM(LTRIM(REPLACE(REPLACE(CONVERT(VARCHAR(30), @Val), '.', ''), '0', ' '))), ' ', '0')SET @Val = 0.01SELECT REPLACE(RTRIM(LTRIM(REPLACE(REPLACE(CONVERT(VARCHAR(30), @Val), '.', ''), '0', ' '))), ' ', '0')SET @Val = 1SELECT REPLACE(RTRIM(LTRIM(REPLACE(REPLACE(CONVERT(VARCHAR(30), @Val), '.', ''), '0', ' '))), ' ', '0')SET @Val = 0010.20301SELECT REPLACE(RTRIM(LTRIM(REPLACE(REPLACE(CONVERT(VARCHAR(30), @Val), '.', ''), '0', ' '))), ' ', '0') Jeff Moden SSC-Forever Group: General Forum Members Points: 45006 Visits: 39880 Why do you think you need the extra overhead of RTRIM/LTRIM when converting Decimal to Varchar? --Jeff ModenRBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.First step towards the paradigm shift of writing Set Based code: Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.Although change is inevitable, change for the better is not.Just because you can do something in PowerShell, doesnt mean you should.

Maybe I just missed the problem altogether...Must be having a bad day or something. Ninja's_RGR'us SSC-Insane Group: General Forum Members Points: 20931 Visits: 9671 Cancel that, I'm having a great day, this is why I came up with this solution : declare @i decimal(10,5)Set @i = 1078.734PRINT REPLACE(@i,'.','')--What's needed? 107873400 or 1078734Set @i = 0.034PRINT REPLACE(@i,'.','')--003400 OR 34?Set @i = 0.0304PRINT REPLACE(@i,'.','')--003040 OR 304?--Now Jeff, let's see your solution to crap out those leading and trailing 0s. Ninja's_RGR'us SSC-Insane Group: General Forum Members Points: 20931 Visits: 9671 Tomm Carr (9/28/2007)The problem with using the Replace string function is that 10.341 ends up as 1034100 if the numeric is defined with five places. If you want 10.342 to end up as 10341, 10.73 as 1073, 10.733 as 10733, 10.7333 as 107333 and 10.7 as 107, then the best way is to use numeric processes rather than string. The only thing is, you have to define your working number to have enough places to the left to contain the entire value. So your example of storing 10.341 into a variable defined as decimal(5,4) is bogus--it only has one place to the left of the decimal point. So if your value is defined as "decimal(x,y)" then you have to declare a working variable as "decimal(x+y,y)" to contain the entire finished value.`declare @Original decimal( 10, 5 ), @Working decimal( 15, 5 ), -- 10 + 5 = 15 @Result decimal( 15, 0 ); -- Doesn't need scale, only precisionSet @Original = 1078.734; -- This would be, say, an input parameter-- First, make a copy into the working variable capable of handling it.Set @Working = @Original;-- Now set up the loopSet @Result = Floor( @Working );While @Result < @Working begin Set @Working = @Working * 10; Set @Result = floor( @Working ); end--whileselect @Result as Result, @Working as Working;`The loop executes one time through for each significant digit to the right of the decimal point -- in this example, three times. The result is 1078734 instead of 107873400.As an aside, does anyone know how to get the old "
" formatting back? This code IFCode shortcut sucks. Sure, the code goes into a nice text field  but everything is double spaced. Sorry Tomm, I had missed your post.  Your solution is much much workable than mine.
