#鸿蒙学习大百科#关系型数据库如何将本设备的数据同步到其他设备？

// 构造用于同步分布式表的谓词对象
let predicates = new relationalStore.RdbPredicates('EMPLOYEE');
// 调用同步数据的接口
if(store != undefined)//store实例的获取省略
{
  (store as relationalStore.RdbStore).sync(relationalStore.SyncMode.SYNC_MODE_PUSH, predicates, (err, result) => {
    // 判断数据同步是否成功
    if (err) {
      console.error(`Failed to sync data. Code:${err.code},message:${err.message}`);
      return;
    }
    console.info('Succeeded in syncing data.');
    for (let i = 0; i < result.length; i++) {
      console.info(`device:${result[i][0]},status:${result[i][1]}`);
    }
  })
}
