The parameters of db.Database.ExecuteSqlCommandAsync(...) in method DefaultLolitaUpdateExecutor.ExecuteAsync(...) are in the wrong order，add a custom class implement ILolitaUpdateExecutor in your project and replace the default DefaultLolitaUpdateExecutor with it can resolve this issue. Only one different place: return db.Database.ExecuteSqlCommandAsync(sql, cancellationToken, param); should be changed to return db.Database.ExecuteSqlCommandAsync(sql, param, cancellationToken);
