推荐答案

PreparedStatement stmt = conn.prepareStatement("INSERT INTO Registration1(RegistrationNo,Date,SeniorPerson,NativePlace,Kul,Gotra,KulSwami,ResidensialAddress,PinCode,STDcode,TelephoneNo,MobileNo,Email,Website,Education,Branch,BirthDate,BloodGroup) VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");

int col = 1;
stmt.setString(col++, regno);
stmt.setDate(col++, new java.sql.Date(dt.getTime()));  // assuming dt is a java.util.Date
(etc)

stmt.executeUpdate();
