Not sure why you would try EXEC() for this. You just need a SELECT with the understanding that you're fighting integer math. In integer math, 15/100 is 0 (with a 15 remainder that won't show) and 1000/3 will give you 333 (with a 1 remainder that won't show). The following will give you what I think you want.

SELECT (1000/3.0)+(15/100.0);

The reason why that works it because neither 3.0 nor 100.0 are integers and they'll cause the formulas to use something other than integer math.

If your analysis is correct. But this strip of operations corresponds to an interpretation of fields, sort of mini compiler, which translates : ' (WIDTH / 3 ) + ( LONG / 100) ' . The process interprets the width and length in numbers and should run the operation to obtain the final result. '(100/3)+(15/100)'. thanks for your help.

You can use sp_executesql, something like this:

DECLARE @WIDTH decimal(19, 2)

DECLARE @LONG decimal(19, 2)

DECLARE @RESULT decimal(19, 2)

DECLARE @sql nvarchar(4000)

SET @sql = N'( @WIDTH / 3 ) + ( @LONG / 100)'

SET @sql = 'SELECT @RESULT = ' + REPLACE(REPLACE(@sql, '@WIDTH', '100'),'@LONG', '15')

PRINT @sql

EXEC sp_executesql @sql, N'@RESULT decimal(19, 2) OUTPUT, @width decimal(19, 2), @long decimal(19, 2)',

@RESULT OUTPUT, @WIDTH, @LONG

SELECT @result

There is no need for dynamic SQL here. Please post the query you have so far.

Thank you very much everyone for your responses. I resolved my problem by way of sq._exec (). Thank you all .
