无法使用 Java/JSP 将数据插入 Apache Derby 数据库

Question

I am unable to insert data into an Apache Derby database using Java and JSP on a Glassfish server. When I try and do so, I get the error:

java.sql.SQLSyntaxErrorException: The number of values assigned is not the same as the number of specified or implied columns.

However I cannot see where in my code the error is, since as far as I can tell I am using the right values. The relevant segment of code is:

 String sql2 = "INSERT INTO APP.USERS (emailAddress, firstName, lastName, password) VALUES ('?', '?', '?', '?', '?')";
        PreparedStatement statement2 = connection.prepareStatement(sql2);
        int test = 0;
        statement2.setInt(0, test);
        statement2.setString(1, emailAddress);
        statement2.setString(2, firstName);
        statement2.setString(3, lastName);
        statement2.setString(4, password);
        statement2.executeUpdate();

Answer 1

Don't put the question marks in single quotation marks. Your VALUES clause should look like VALUES(?,?,?,?)
