Question

I have the folowing SQL query:

SELECT * from sales WHERE cdate = (SELECT CONVERT(char(11), GETDATE(),20)) 

With this result:

ID  NO      DATE                    AMOUNT

9   103100  2012-01-31 00:00:00.000 44.29

10  110150  2012-01-31 00:00:00.000 2360.93

11  114000  2012-01-31 00:00:00.000 63.60

12  217155  2012-01-31 00:00:00.000 717.27

How can I add the values in the last column (amount)?

Answer 1

Use query:

SELECT SUM(AMOUNT)
FROM YourTable
WHERE cdate = (SELECT CONVERT(char(11), GETDATE(),20)) 

and read in c#:

using(SqlCommand sc = YourOpenConnection.CreateCommand())
{
  sc.CommandText = @"
  SELECT SUM(AMOUNT)
  FROM YourTable
  WHERE cdate = (SELECT CONVERT(char(11), GETDATE(),20)) 
  ";
  Console.WriteLine(sc.ExecuteScalar());
}
