jTable和SQL数据检索

Question

First post, If I made a mistake please forgive me!

On my jTable "ID", "Name" values from the database show up but the "balance" doesn't!

What's the reason?

Here's the source code :

    private void formWindowOpened(java.awt.event.WindowEvent evt) {                                  
        // TODO add your handling code here:
        Tools.setCenter(this);

        DAL d = new DAL();

        Object[][] Customer = d.select("select * from customer");

        String[] column = {"ID", "Name", "Balance"};

        jTable1 = new javax.swing.JTable(Customer, column);
        jScrollPane1.setViewportView(jTable1);

    }                                 

    private void jTextField1KeyPressed(java.awt.event.KeyEvent evt) {                                       
        // TODO add your handling code here:

        if (evt.getKeyCode() == 27) {

            this.setVisible(false);

        }
    }

You are not mentioning the exact code needed!! Hope that you have created table with 3 columns.. Try this code

ps=con.prepareStatement("select * from customer");
rs=ps.exectuteQuery();
while(rs.next()) 
{
int row=0;
for(int i=1,i<=rsmd.getColumnCount();i++)
{   
jTable1.setValueAt(rs.getString(i),row,i-1);
}
row=row+1; 
}
