The table after executing the drop user statement is as follows:
Use the DROP USER statement to delete multiple users: You can use the DROP USER statement to delete multiple user accounts at one time. To delete the two user accounts "gfguser2" and "gfguser1" from the above table, you should execute the following delete user statement:
