Removes a user account.


DROP USER user-name


Argument Description
user-name The name of the user to be removed.


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 window 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, it is necessary to be logged in as a user with appropriate privileges. Failing to do so results in an SQLCODE -99 error (Privilege Violation).

Use the $SYSTEM.Security.Login()Opens in a new window method to assign a user with appropriate privileges:

   DO $SYSTEM.Security.Login("_SYSTEM","SYS")
   &sql(      )
Copy code to clipboard

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 window in the InterSystems Class Reference.


You can drop PSMITH by issuing the statement:

DROP USER psmith
