I have users called Admin and Users.
I given all access rights for admin.
As i know we can give permissions for a table but not for particular fields.
Is it possible to give permissions/access rights for fields?
For Example: In table 'x' there are 2 fields called name and ph.num, we can create a group for table 'x' for Admin and give rights to edit name and ph.num. And i will create another group for same table 'x' for User that he can edit only ph.num. If i login as User he can change both name and ph.num, So my question is to edit only one ph.num field. How can we do this?
