Advantage SQL Engine
Delete a user object from the database.
sp_DropUser( UserName,CHARACTER,50 )
Name of the user object to delete.
AE_INVALID_OBJECT_NAME Possible cause for the error is that the UserName is not a valid user name in the database.
sp_DropUser removes an existing user from the database. Once the user is removed from the database, any future connection attempts to the database using the specified user name will fail with authentication error. Any existing connections by the user will still be valid. However, those connections may not be able to open table or execute SQL statement if the database is set up to verify the users’ access rights. If the database is not set up to verify the users’ access rights, those connection can still open table and execute SQL statement. See sp_ModifyDatabase for information on setting up user access rights verification.
After making a connection to the database, delete the user named "User1" from the database.
EXECUTE PROCEDURE sp_DropUser( ‘User1’ );
