Use SQLQueryFactory for container DB
Needed to add a Filter possibility to facilitate that
Created a Simple UserString class which can be used as:

```py
        sql_filter = SQLFilter(f"SELECT {{}} FROM table_name WHERE id = ?")
        cursor.execute(sql_filter)  # Will execute: SELECT * FROM table_name WHERE id = ?
        cursor.execute(sql_filter["id", "name"])  # Will execute: SELECT id, name FROM table_name WHERE id = ?

```
