Description
I'm setting it to minor, because it is apparently intentional. I can't find it in the KB, but at least the MySQL manual says:
SHOW COLUMNS displays information only for those columns for which you have some privilege
so one can say that CREATE grant doesn't give any column privileges, thus nothing is shown.
It doesn't seem logical though, if I can see all the columns through SHOW CREATE TABLE anyway, why cannot I see them via SHOW COLUMNS or from INFORMATION_SCHEMA.COLUMNS.
create database db; |
create table db.t (a int); |
|
|
create user u@localhost; |
grant create on db.t to u@localhost; |
|
|
--connect (con1,localhost,u,,db)
|
show create table db.t; |
show columns in db.t; |
select table_name, column_name from information_schema.columns where table_name = 't'; |
|
|
# Cleanup
|
--disconnect con1
|
--connection default
|
drop user u@localhost; |
drop database db; |
|
Actual result, 10.4 b1c8ea83 |
