count statement should return number but it got NULL

[xwanlion]

abstract dao class:

  @Query('SELECT count(1) num FROM v_todo where deleted = 0 and state = :state')
  Future<int?> count(int state);

generated dao class:

@override
  Future<int?> count(int state) async {
    await _queryAdapter.queryNoReturn(
        'SELECT count(1) num FROM v_todo where deleted = 0 and state = ?1',
        arguments: [state]);
  }

why is queryNoReturn, not a number?

The support of scalar return values need some development. See #576

Ultimately #200 will introduce a new SQL query analyzer to support cases like this. Major change.

[xwanlion]

all right

[MrCsabaToth]

Unfortunately #361 got abandoned, need to be rewritten from scratch
