Question

我在Ionic中有非常简单的代码。我只是从ionicframwork docs复制代码。目前还没有工作。我无法进行选择或插入请求。这是我的代码：

this.sqlite.create({
            name: 'sub.db',
            location: 'default'
        })
            .then((db:SQLiteObject) => {
                db.executeSql('create table danceMoves(name VARCHAR(32))', {})
                    .then(() => console.log('Executed SQL'))
                    .catch((e) => console.log(e));
            })
            .catch((e) => console.log(e));

昨天一切正常，今天我有一个错误：

Answer 1

我觉得最近发生了类似的事情。添加平台就绪验证后，它对我有用。类似的东西：

  constructor(public nav: NavController, public platform: Platform, public sqlite: SQLite ,...) {
     let _this = this; //Not sure if this is needed
    platform.ready().then(() => {

      _this.sqlite.create({
         name: 'sub.db',
         location: 'default'
        })
        .then((db:SQLiteObject) => {
            db.executeSql('create table danceMoves(name VARCHAR(32))', {})
                .then(() => console.log('Executed SQL'))
                .catch((e) => console.log(e));
        })
        .catch((e) => console.log(e));
    });
  }

我希望这可以帮到你

Answer 2

你应该调用SQLiteObject对象实例的close（）方法。

this.sqlite.create({
            name: 'sub.db',
            location: 'default'
        })
            .then((db:SQLiteObject) => {
                db.executeSql('create table danceMoves(name VARCHAR(32))',{})
                    .then(() => {
                        console.log('Executed SQL');
                        db.close(); // <---------------
                     })
                    .catch((e) => console.log(e));
            })
            .catch((e) => console.log(e));
