Data Populated in a single row??

Hi,

I have a requirement as follows:

Suppose there is a column "A". There many be "n" no. of records for that column "A"

I want the code logic for this to sum up all the "n"  no. of records,which is of  type amount and to be populated in a single row.

Ex :

Column A

7867.68

5658.65

566765.44

'

'

'

n

like this "n"  no. of records would be populated (at the runtime).

I need the output as :

Column A

SUM(7867.68 + 5658.65 + 566765.44 + .......n) in a single row.

Immediate reply would be greatly appreciated.

Thanks in advance,

Regards,

Vamc
