Question

我正在使用Ionic 2和SQLite尝试在表中插入注释，而point_id等于特定匹配的第二个最高point_id。所以我写了下面的查询，但Ionic 2正在抛弃我

sqlite3_prepare_v2 failure: no such column: match_id

INSERT INTO comments (point_id, match_id, comment, created_at)
VALUES((
   SELECT name.point_id 
   FROM (
       SELECT point_id from undo 
       WHERE match_id = ? 
       ORDER BY point_id DESC 
       LIMIT 2) AS name 
   WHERE match_id = ? 
   ORDER BY point_id LIMIT 1), ?, ?, ?)

我的整个离子2代码是

NativeStorage.getItem('matchID').then(matchID => {
          let query = 'INSERT INTO comments (point_id, match_id, comment, created_at) '+
                      'VALUES((SELECT name.point_id FROM (SELECT point_id from undo WHERE match_id = ? ORDER BY point_id DESC LIMIT 2) AS name WHERE match_id = ? ORDER BY point_id LIMIT 1), ?, ?, ?)';
            this.db.executeSql(query, [matchID.value, matchID.value, matchID.value, data.comment, new Date()]).then(data_comment => {
              let toast = this.toastCtrl.create({
                message: 'Comment was added successfully',
                duration: 2000,
                position: 'top'
              });

              toast.present();
              console.log("comment entered", data_comment);
            }, err => console.error("ERROR enter comment in match tracker ", err))
          })

非常感谢。

我改变了我的SQLite查询，现在它工作正常。如果其他人需要这个，那就是：

INSERT INTO comments (point_id, match_id, comment, created_at)
VALUES((
    SELECT point_id from undo 
    WHERE match_id = ? 
    ORDER BY point_id DESC 
    LIMIT 1 OFFSET 1), ?, ?, ?)

如何使用选定的值为SQLite编写插入查询
