flutter - 如何在Flutter中使用SQFLite创建多个表？

Question

我正在使用sqflite数据库。当我尝试创建一个表时，它可以完美地工作。但是，当我添加一些其他SQL代码来创建其他表时，出现此错误:

error DatabaseException(near ",": syntax error (code 1 SQLITE_ERROR): , while compiling: CREATE TABLE deletednotes(id INTEGER PRIMARY, title TEXT, description TEXT, priority INTEGER, date int)) sql 'CREATE TABLE deletednotes(id INTEGER PRIMARY, title TEXT, description TEXT, priority INTEGER, date int)' args []} during open, closing...

如何正确创建多个表？

这是我的查询:

  void _createDB(Database db, int version) async {
    await db.execute('''CREATE TABLE $notetable(
          $COL_ID INTEGER PRIMARY KEY AUTOINCREMENT, $COL_TITLE TEXT, $COL_DESCRIPTION TEXT, $COL_PRIORITY INTEGER, $COL_DATE int)''');

    await db.execute(
        '''CREATE TABLE $archievedtable($COL_ID INTEGER PRIMARY KEY, $COL_TITLE TEXT, $COL_DESCRIPTION TEXT, $COL_PRIORITY INTEGER, $COL_DATE int)''');

    await db.execute(
        '''CREATE TABLE $deletedtable($COL_ID INTEGER PRIMARY, $COL_TITLE TEXT, $COL_DESCRIPTION TEXT, $COL_PRIORITY INTEGER, $COL_DATE int)''');
  }

可能会有一些语法错误，有什么想法吗？

const变量:

  static const COL_TITLE = "title";
  static const COL_DESCRIPTION = "description";
  static const COL_PRIORITY = "priority";
  static const COL_DATE = "date";

  String notetable = "notes";
  String deletedtable = "deletednotes";
  String archievedtable = "archievednotes";```

将SQL代码中的int替换为INTEGER并更改以下内容
在声明主键之后添加关键字KEY的行:
await db.execute( '''CREATE TABLE $deletedtable($COL_ID INTEGER PRIMARY, $COL_TITLE TEXT, $COL_DESCRIPTION TEXT, $COL_PRIORITY INTEGER, $COL_DATE int)''');。

至:
await db.execute( '''CREATE TABLE $deletedtable($COL_ID INTEGER PRIMARY KEY, $COL_TITLE TEXT, $COL_DESCRIPTION TEXT, $COL_PRIORITY INTEGER, $COL_DATE int)''');
