To disable a created database account, you can delete it in the TencentDB for SQL Server Console.
In order to avoid accidental deletion from interrupting normal use by your business, you need to make sure that the database account to be deleted is no longer used by any applications.
Log in to the TencentDB for SQL Server Console. In the instance list, click an instance name or Manage in the "Operation" column to enter the instance management page.
Select the Manage Account tab, select the target account, and click Delete Account in the "Operation" column.
In the pop-up dialog box, click Delete.
