Answer 2

试试这个：

String sql = "INSERT INTO reseve1(Customer_Name, Contact_Number, Email_Address, Venue, Date, Time, Price, Balance) " + 
"VALUES (:cname,:cnumber,:mail,:location,:dateValue,:timeValue,:priceVal,:balanceAmount)";

SQLQuery query = session.createSQLQuery(sql);


query.setString("cname", cx1.getText());
query.setInteger("cnumber", contactnum11.getInt());
query.setString("mail", email1.getText());
query.setString("location", venuee.getText());
query.setString("dateValue", Date1);
query.setString("timeValue", Time1.getText());
query.setString("priceVal", venuee.getInt());
query.setInteger("balanceAmount", Balance.getInt());
query.executeUpdate();
