Dear Vipin dev,
Actually, I just want to remove the columns with NULL value. If I use ISNULL(NEWYORK,0), the column still in the result set and column name is 0.
Is there anyway I can do it ?

Thanks in advance,

I think what you want is COALESCE

select COALESCE(fieldname, 0)

COALESCE will select the first non null from a list so you can even have

select COALESCE(field1,field2,field3,field4, 0)

Hi, all

select convert(varchar,(datediff(dd,'1979-09-04 12:34:50.603',getdate())/365))

here getdate()='2007-09-05 12:34:50.603'

I need find the age of employee but this result is showing 28 instead of 27

How are you getting the age, Are you using DATEDIFF ?

Try something like this for a more accurate result:

SELECT
    YEAR(GETDATE()) - YEAR('1979-09-04 12:34:50.603') - 
    CASE
        WHEN DATEPART(dayofyear,GETDATE()) < DATEPART(dayofyear,'1979-09-04 12:34:50.603') THEN 1
        ELSE 0
    END AS Age

Why do you use

<br />
<br />
DATEDIFF(YY, @tartdate, getdate())<br />
<br />
<br />
<br />

Don't know which version of SQL Server you are using. If 2000 then below written sql will solve the problem. If you are using 2005 then you can use ROW_NUMBER() instead of IDENTITY() and there is no need for #TempTable. If you are using 2000 and table has a Identity column then also there is no need for #TempTable.

Identity Column or the higher version (2005) will help you to do in single sql stmt...

select <br />
IDENTITY(INT, 1, 1)AS KeyCol, Col1, col2, col3 into #TempTable from tbldistinct<br />
<br />
select col1,col2,col3 from #TempTable B<br />
where (Select Count(*) from #TempTable A where A.col1 = B.col1 and A.KeyCol <= B.KeyCol) =1<br />
<br />
Drop Table #TempTable

Use a groupby would be the easiest why without DISTINCT

<br />
select col1, col3, col3<br />
from table<br />
ORDER BY col1, col3, col3<br />

Dear John,
I'm sorry that my question confuse you. Actually, I just need the result with the Column names that has maximum values.

Let me try to be clear.
Here is the result of my query.

Department City1 City2 City3 City4 City5 City6

Operations 4 2 6 NULL 1 NULL
Risk Management 4 5 1 NULL 2 NULL
Technology 2 3 5 NULL 1 NULL

I want to remove the column with NULL values.
That's exactly what I want.

Thanks ,
RB

I think I know what you want

<br />
SELECT * from TABLE<br />
ORDER BY City DESC<br />

ORDER BY WITH SUM

<br />
SELECT *, SUM(City1 + City2 + City3 + City4 + City5 + City6) as Total<br />
  from TABLE<br />
ORDER BY Total DESC<br />

I can imagine you have a problem with a xml-file when it is comma seperated.
