java.sql.SQLException：sqlite3_step失敗：無法回滾 - 沒有事務處於活動狀態

Question

我在Ionic中有非常簡單的代碼。我只是從ionicframwork文檔複製代碼。它目前沒有工作。我無法進行選擇或插入請求。這裏是我的代碼：

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，今天我有一個錯誤：

Answer 1

我想類似的事情最近發生在我身邊。 我在添加Platform ready驗證後爲我工作。一些與此類似：

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)); 
    }); 
    } 

我希望這可以幫助你

Answer 2

你應該調用close SQLiteObject對象實例（）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));
