java - 如何在一个PrepareStatement (sqlite) 中使用Array 或List<>

Question

我尝试了很多时间来解决这个问题，所以感谢您的帮助。 如何在prepare语句中使用数组？我在这个例子中这样做 How to use an arraylist as a prepared statement parameter但它返回错误，我的代码:

        //initialize
        ResultSet rs2; 
        connection2 = sqliteConnection.dbConnector(); 
        PreparedStatement statement2=connection2.prepareStatement("SELECT surname FROM users where id IN (?)");

        //like in the example linked, but it did not work:   
        Array array = connection2.createArrayOf("VARCHAR", new Object[]{"1", "2"});
        statement2.setArray(1, array);
        rs2=statement2.executeQuery();

        //to keep data from resultset, it works fine
        List<String> rsDATA = new ArrayList<String>();
        while(rs2.next()){ 
            rsDATA.add(rs2.getString("surname")); 
        }   
        for(int i = 0; i < rsDATA.size(); i++) {
            System.out.println(rsDATA.get(i));
        }
        connection.close();

但它返回错误:

Exception in thread "AWT-EventQueue-0" java.lang.AbstractMethodError: org.sqlite.SQLiteConnection.createArrayOf(Ljava/lang/String;[Ljava/lang/Object;)Ljava/sql/Array;
at lines: 

1)Array array = connection2.createArrayOf("VARCHAR", new Object[]{"1", "2"});
2(executeQuery();

解决这个问题对我来说非常重要。非常感谢..

您需要在 WHERE 子句中使用 IN:

SELECT surname FROM users WHERE id IN (?)

和一个 java.sql.Array 对象，如链接问题的答案所示。
