Use user1 to log in and view the resource group bound to the current user.

SELECT CURRENT_RESOURCE_GROUP();
+--------------------------+ | CURRENT_RESOURCE_GROUP() | +--------------------------+ | rg1 | +--------------------------+ 1 row in set (0.00 sec)

Execute SET RESOURCE GROUP to set the resource group for the current session to rg2.

SET RESOURCE GROUP `rg2`; SELECT CURRENT_RESOURCE_GROUP();
+--------------------------+ | CURRENT_RESOURCE_GROUP() | +--------------------------+ | rg2 | +--------------------------+ 1 row in set (0.00 sec)

Execute SET RESOURCE GROUP to specify the current session to use the default resource group.

SET RESOURCE GROUP `default`; SELECT CURRENT_RESOURCE_GROUP();
+--------------------------+ | CURRENT_RESOURCE_GROUP() | +--------------------------+ | default | +--------------------------+ 1 row in set (0.00 sec)

MySQL compatibility

MySQL also supports SET RESOURCE GROUP. But the accepted parameters are different from that of TiDB. They are not compatible.
