SqfLite 没有这样的 table(代码 1 SQLITE_ERROR)
SqfLite No such table (code 1 SQLITE_ERROR)
也许这个问题已经得到解答,但我尝试将 sqfLite 添加到我的项目中,但出现此错误:
在我的调试控制台中:
no such table: infotable in "SELECT * FROM infotable"
这是我的代码:
final String infoTable = 'infotable';
final String columnID = '_id';
final String columnName = 'name';
final String columnCivilStatus = 'civil';
final String columnWorking = 'working';
final String columnJobTitle = 'job';
final String columnWorkingDomain = 'workingdomain';
final String columnMonthlyIncome = 'monthlyincome';
class SqfLite {
int id;
int sliderValue;
int monthChoiceChip;
String reasonChoiceChip;
String name;
String civilStatus;
int working;
String jobTitle;
int workingDomain;
String monthlyIncome;
String currency;
Position latitude;
Position longitude;
Map<String, dynamic> toMap() {
var map = <String, dynamic>{
columnCivilStatus: civilStatus,
columnJobTitle: jobTitle,
columnMonthlyIncome: monthlyIncome,
columnWorkingDomain: workingDomain,
columnWorking: working,
columnName: name,
};
if (id != null) {
map[columnID] = id;
}
return map;
}
SqfLite();
SqfLite.fromMap(Map<String, dynamic> map) {
id = map[columnID];
name = map[columnName];
civilStatus = map[columnCivilStatus];
working = map[columnWorking];
jobTitle = map[columnJobTitle];
workingDomain = map[columnWorkingDomain];
monthlyIncome = map[columnMonthlyIncome];
}
}
class SqfLiteProvider {
Database db;
Future open(String path) async {
db = await openDatabase(path, version: 1,
onCreate: (Database db, int version) async {
await db.execute('''
create table $infoTable (
$columnID integer primary key autoincrement,
$columnName text not null,
$columnCivilStatus text not null,
$columnWorking integer not null,
$columnJobTitle text not null,
$columnWorkingDomain integer not null,
$columnMonthlyIncome text not null)
''');
});
}
Future<SqfLite> getSqfLite(int id) async {
List<Map> maps = await db.query(infoTable,
columns: [
columnID,
columnName,
columnCivilStatus,
columnWorking,
columnJobTitle,
columnWorkingDomain,
columnMonthlyIncome,
],
where: '$columnID = ?',
whereArgs: [id]);
if (maps.length > 0) {
return SqfLite.fromMap(maps.first);
}
return null;
}
Future close() async => db.close();
}
我在这里得到错误:
Future<void> openDataBase() async {
db = await openDatabase('infotable.db');
records = await db.query('infotable');
mapRead = records.first;
....
}
我已经按照 plugin
的官方页面中的示例进行操作
由于某些pubspec.yaml
冲突,我无法使用最新版本。
我已尝试 flutter clean
并重新安装该应用程序,但没有成功
您在 SqfLiteProvider
中定义了 open
方法,但您没有使用它。相反,您从未定义 onCreate
回调的 sqflite 包中调用相同的 openDatabase('infotable.db');
方法 - 您会收到错误消息。
因此,不要直接调用 db = await openDatabase('infotable.db');
,而是使用您定义的 SqfLiteProvider.open()
。
