Не удается обновить базу данных SQL Server

-1

В Sql Server Management Studio я обновляю базу данных с сохранением идентификатора в качестве первичного ключа. Из ComboBox я показываю все ID и после нажатия кнопки отправки все детали отображаются в jTextField, чтобы соответствовать различным ярлыкам, имеющим имя в качестве столбца в базе данных. Здесь все мои данные отображаются правильно. И есть кнопка сброса, которая удаляет детали некоторых ярлыков, даже я получаю правильный этот алос. Но я не могу обновлять таблицы. Я пишу код ниже. Пожалуйста, помогите, а что неправильно в коде;Не удается обновить базу данных SQL Server

RU, что имена столбцов имеют пробела в них «Совокупный Marks = ?, Campus Eligiblity =? ", в обновлении ur? Посмотрите на структуру таблицы один раз. – Arvind

Ват, вы получите как исключение в консоли. – Arvind

Mr.Arvind, была ошибка орфографии в имени столбца, которую я исправил, но все же у меня такие же ошибки. – amish3110

Проблема эта часть (?)

String query = "Update Details set Aggregate Marks=?,Campus Eligibilty=?,Email=?,Mobile=? where ID='"+str+"'"; 
PreparedStatement stmt=con.prepareStatement(query); 
int rs = stmt.executeUpdate(query); 
stmt.setString(4,st5); 
stmt.setString(5,st3); 
stmt.setString(6,st4); 
stmt.setString(7,st6);

Ваш SQL содержит заполнители, но вы звоните stmt.executeUpdate(), прежде чем вы назначить значения для тех заполнителей. Вы также используете неправильные номера для тех заполнителей в этих строках, она должна быть от 1 до 4, а не 4 до 7.

stmt.setString(1, st5); 
stmt.setString(2, st3); 
stmt.setString(3, st4); 
stmt.setString(4, st6); 
int rs = stmt.executeUpdate(); // shouldn't need to pass query back in
