Try changing the query to:
SELECT Count(tblUsers.status) AS num, username
FROM tblUsers
GROUP BY tblUsers.username
u can group by the fields in the select list. Status is not in the select
list (only username is).

Please help me out.
I have query (SQL Server7.0)
SELECT Count(tblUsers.status) AS num, username
FROM tblUsers
GROUP BY tblUsers.username,tblUsers.status
However, the ResultSet.getInt("num") gave me error:
javax.servlet.ServletException: [Microsoft][ODBC SQL Server
Driver]Invalid Descriptor Index
java.sql.SQLException: [Microsoft][ODBC SQL Server Driver]Invalid
Descriptor Index
I don't know what data type of 'num' should be, and how to fix this error.
Please help.
Thanks,
Leo.

out.println(String.valueOf(rs1.getInt("num")) //error here....
}
