As discussed here, and here, we can use wildcard when granting privileges to user.
grant all on `someSchema\_%`.* to `someUser`@`%`;
Though wildcard CANNOT be applied to table name i.e.
grant all on `someSchema\_%`.`someTable%` to `someUser`@`%`;
grant all on `someSchema\_%`.`someTable\_` to `someUser`@`%`;
My google search results non-helpful so I ask here - how can we use wildcard
for BOTH schema name and table name in MySQL GRANT
command?
