我使用Ionic& amp ;;构建移动应用程序我和Cordova需要将数据存储在本地数据库的几个表中,所以我使用SQLite。
在我的app.js中我有这个:
var db = null;
var weatherApp = angular.module('weather', ['ionic', 'ngCordova']);
weatherApp.run(function($ionicPlatform, $cordovaSQLite, Cities) {
$ionicPlatform.ready(function() {
if(window.cordova) {
db = $cordovaSQLite.openDB({name: 'weather.db', location: 'default'});
create table for storing favourites
$cordovaSQLite.execute(db, 'CREATE TABLE IF NOT EXISTS favourites (id integer primary key, name text, openWeatherId integer)');
create table for storing the current location of the device
$cordovaSQLite.execute(db, 'CREATE TABLE IF NOT EXISTS location (id integer primary key, openWeatherId integer');
//also tried
// db.transaction(function (tx) {
// //create table for storing favourites
// tx.executeSql(db, 'CREATE TABLE IF NOT EXISTS favourites (id integer primary key, name text, openWeatherId integer)');
// });
// db.transaction(function (tx) {
// //create table for storing the current location of the device
// tx.executeSql(db, 'CREATE TABLE IF NOT EXISTS location (id integer primary key, openWeatherId integer');
// });
$cordovaSQLite.execute(db, 'SELECT tbl_name FROM sqlite_master WHERE type = "table"').then(function (res) {
var tables = [];
if (res.rows.length > 0) {
for (var i = 0; i < res.rows.length; i++) {
if (res.rows.item(i).tbl_name !== "android_metadata"){
tables.push(res.rows.item(i).tbl_name);
}
}
console.log(tables);
// gives:
// Array(1)
// 0 : "favourites"
} else {
console.log('no tables in db!');
}
}, function (error) {
console.log(error);
});
}
});
});

当我在物理Android设备上运行此(cordova运行android)时,只创建了1个表,收藏夹,其他位置不是。
任何想法为什么?谢谢!
答案 0 :(得分:1)
第二个SQL查询中有一个拼写错误:
$cordovaSQLite.execute(db, 'CREATE TABLE IF NOT EXISTS location (id integer primary key, openWeatherId integer');
关闭括号修复了问题:
$cordovaSQLite.execute(db, 'CREATE TABLE IF NOT EXISTS location (id integer primary key, openWeatherId integer)');
