hi zhaoyh
This is ashok.Thanks a lot for ur reply.I corrected my mistake.
I have a problem on setting the result in a JTextField for the following query.
"select SUM(Total) from Record where Date=? AND MedicalName=?"
if execute this query in MSAccess or in Oracle as
SELECT SUM(Total) FROM Record WHERE Date=06/10/2005 AND MedicalName='Sakthi'
Cosole shows Expr1000
34000.5
Expr1000 is not a column in my table.But i need to set 34000.5 in my JTextField.
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con=DriverManager.getConnection("jdbc:odbc:ashok", " ", " ");
pstat=con.prepareStatement("select SUM(Total) from Record where Date=? AND MedicalName=?");
pstat.setString(1,(String)jList11.getSelectedValue());
pstat.setString(2,(String)jComboBox1.getSelectedItem());
r1=pstat.executeQuery();
jTextField1.setText(// HERE I NEED THE RESULT WHICH IS DISPLAYED ABOVE IN CONSOLE OF MS ACCESS OR IN ORACLE
catch(Exception e)
System.out.println("GRAND T :"+e);
Pls help to solve this problem .
