Removes a user account.
The DROP USER command removes a user account. This user account was created and the user-name specified using CREATE USER. If the specified user-name does not correspond to an existing user account, InterSystems IRIS issues an SQLCODE -118 error. You can determine if a user exists by invoking the $SYSTEM.SQL.Security.UserExists()Opens in a new tab method.
User names are not case-sensitive.
You can also delete a user by using the Management Portal. Select System Administration, Security, Users to list the existing users. On this table of user accounts you can click Delete for the user account you wish to delete.
The DROP USER command is a privileged operation. Prior to using DROP USER in embedded SQL, you must be logged in as a user with one of the following:
The %Admin_Secure administrative resource with USE permission
The %Admin_UserEdit administrative resource with USE permission
Full security privileges on the system
If you are not, the DROP USER command results in an SQLCODE -99 error (Privilege Violation).
Use the $SYSTEM.Security.Login()Opens in a new tab method to assign a user with appropriate privileges:
You must have the %Service_Login:Use privilege to invoke the $SYSTEM.Security.Login method. For further information, refer to %SYSTEM.SecurityOpens in a new tab in the InterSystems Class Reference.
