Permissions
Execute permissions default to the public role.
sp_helpdb must access the database(s) on the server to determine the information to be displayed about the database. Therefore, for each database on the server, one of these must apply:
- The user executing sp_helpdb must have permissions to access the database.
- The guest user account must exist in the database.
If a database cannot be accessed, sp_helpdb displays error message 15622 and as much information about the database as it can.
