String query = "insert into transaction(applicationid, customername, customerage, customeraddress, pincode, status, edate, progress, euserid) 
 
VALUES(?,?,?,?,?,?,?,?,?)"; // The total ? is 9 as your total columns is 9 
 

 
PreparedStatement ps1=(PreparedStatement) con.prepareStatement(query); 
 
       ps1.setInterger(1,id); // set your datatype whatever it is 
 
       ps1.setString(2,name); // set your datatype whatever it is 
 
       ps1.setInteger(3,age); // set your datatype whatever it is 
 
       ps1.setString(4,address);// set your datatype whatever it is 
 
       ps1.setInteger(5,pincode);// set your datatype whatever it is 
 
       ps1.setString(6,status); // set your datatype whatever it is 
 
       ps1.setString(7,CurrentDate);// set your datatype whatever it is 
 
       ps1.setString(8,progress);// set your datatype whatever it is
