Hello
thanks for your help
I want to share the final result that I received thanks to his advice
To obtain the list of users, the following query must be executed:
SELECT SI_ID, SI_NAME,SI_ENT_USERFULLNAME,SI_DESCRIPTION,SI_OBTYPE FROM CI_SYSTEMOBJECTS WHERE SI_OBTYPE = 19
The result is presented in blocks and not in rows
I leave the query to obtain the list of groups
SELECT SI_ID, SI_NAME,SI_ENT_USERFULLNAME,SI_DESCRIPTION,SI_OBTYPE FROM CI_SYSTEMOBJECTS WHERE SI_OBTYPE = 20
