Использование ExecuteAsync работает для создания, вставки и т. Д., Но не для выбора.Это два запроса, которые работают: CREATE TABLE t(x INTEGER PRIMARY KEY ASC, y, z) и insert into t(y, z) values(2, 2)
Но select не работает.Это мой код:
SQLiteAsyncConnection conn = new SQLiteAsyncConnection(App.Databaselocation);
var result = await conn.ExecuteAsync("select y from t");
И выдает исключение SQLiteException:
