Dear All,
Find the following sample.I am executing dynamic sql to populate the value.The Formula string will come Case when or direct((100/0.1)*.5) like that.

Currently i am executing the String in WHILE loop.Is it possible with out while or cursor can we have execute the string value SET Based the strings are stored in table rows.

drop table #DYNAMICFORMULAS
CREATE TABLE #DYNAMICFORMULAS
(
EMPLOYEE_ID NUMERIC(10),
ACTUAL_AMOUNT VARCHAR(200),
EARNED_AMOUNT VARCHAR(200),
PAY_DATE DATETIME
)

DECLARE @mFormulaString1 VARCHAR(200)
DECLARE @mFormulaString2 VARCHAR(200)
DECLARE @msql NVARCHAR(400)

INSERT INTO #DYNAMICFORMULAS VALUES(1,'0','0','31-JAN-2014')
SET @mFormulaString1='CASE WHEN ISNULL(1,0)=1 THEN 0.12*(1000.000) ELSE 0 END'
SET @mFormulaString2='CASE WHEN ISNULL(1,0)=1 THEN 0.12*(1500.000) ELSE 0 END'


SET @mSQL='
UPDATE #DYNAMICFORMULAS SET
ACTUAL_AMOUNT ='+@mFormulaString1 +','+' EARNED_AMOUNT ='+@mFormulaString2 +'
WHERE
EMPLOYEE_ID=@EmployeeID AND
PAY_DATE=@PayDate'

From what you posted I don't see any need for any looping construct or dynamic sql.

In order to help we will need a few things:

1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data

Please take a few minutes and read the first article in my signature for best practices when posting questions.
