What am I doing wrong in this code? It gives a SQLException that a parameter is out of range while I think I have given the parameter.
try{
String sql = "select item_type as 'Item Type', md_by as 'Made By',"
+ " model as 'Model', selling_price as 'Selling Price', "
+ "purchase_price as 'Purchase Price', "
+ "purchase_date as 'Purchase Date', vouch_no as 'Voucher No.', "
+ "vouch_date as 'Voucher Date', record_no as 'Record No.' "
+ "from purchase where vouch_no = ?";
ps.setInt(1, Integer.parseInt(txt_vouchno_p.getText()));
ps = con.prepareStatement(sql);
rs = ps.executeQuery();
Table_p.setModel(DbUtils.resultSetToTableModel(rs));
}
catch(SQLException ex){
JOptionPane.showMessageDialog(null, "Error: " + ex);
}
catch(Exception ex){
JOptionPane.showMessageDialog(null, "Error: " + ex);
}
Your order of calling methods is wrong. First, you prepare the statement, then you set the bind variable values. Change
ps.setInt(1, Integer.parseInt(txt_vouchno_p.getText()));
ps = con.prepareStatement(sql);
to
ps = con.prepareStatement(sql);
ps.setInt(1, Integer.parseInt(txt_vouchno_p.getText()));
