First of all, sry because I am not a DBA and I'm not familiar with all the permissions.
My question is, if I give a user
db_owner permissions on one database. Do I need to give also
db_datawriter permissions to have full control? I think
db_owner is sufficient to execute all kind of queries on the database? (create, delete, alter, select and all other stuff).
So, in short: If I choose
db_datawriter are automatically included. Am I right?
