Redesign `data_set_sql_query` use SQLAlchemy Query API

Currently the function `data_set_sql_query` does not support other db engines and is mainly raw SQL coded. This should be IMO be changed.

###  Planned changes
* add a new function with a `db` parameter using `functools.singledispatch`
* use the SQLAlchemy Query API to generate the SQL code
* mark the current `data_set_sql_query` function as deprecated
