SET PROPERTY

Description​

Syntax​

SET PROPERTY [FOR 'user'] 'key' = 'value' [, 'key' = 'value']

Set user attributes, including resources allocated to users and etc. The user properties here means the attributes for users, not for user_identity. That is to say, if two users, 'jack'@'%' and 'jack'@'192.%', are created through CREATE USER statement, then SET PROPERTY statement can only be used for user jack, not 'jack'@'%' or 'jack'@'192.%'.
