this approach doesn't work at all:

root@sip:~# kamcli subscriber show vseva
Traceback (most recent call last):

    meth = statement._execute_on_connection
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'str' object has no attribute '_execute_on_connection'

The above exception was the direct cause of the following exception:

    raise exc.ObjectNotExecutableError(statement) from err
sqlalchemy.exc.ObjectNotExecutableError: Not an executable object: "select * from subscriber where username='vseva' and domain='sipwork.pro'"

connection.execute() needs a statement object.

Ok, we need this helper to translate string to statements

from sqlalchemy import text

but then ioutils_dbres_print needs to be updated too:
