This is an original planning guide. It is not a vendor manual, an official standard, or legal advice. Example addresses use documentation ranges. Review every command before you paste it.
What this hour is for
The GRANT builder writes one privilege on one table to one user. The default privilege in the draft is SELECT. The matrix tool writes one GRANT per line you type as role and privilege list. The broad-grant reader flags ALL PRIVILEGES, a superuser-style grant, an account at every host, and GRANT OPTION. If none of those are in the paste, it says so.
Do not grant during the reading. Do not grant every privilege to make a test pass. Do not put a password in the note. One user, one table, a database you administer.
192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the database named in the ticket. Read the draft, then the database, then decide.
Rollback is the backup, the file, or the snapshot you saved first. You do not invent a rollback after the only copy is gone.
- Name the user and the table.
- Read the GRANT.
- Paste a grant list if you have one.
- Do not run GRANT.
- Stop.
Mistakes that outlive the statement
Database User and Role Management goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- GRANT run during the reading.
- ALL PRIVILEGES added to make a test pass.
- A password in the note.
- An account open to every host.
Decisions to write down
One decision for Database User and Role Management: The privilege is one you can say. Nothing was granted. No password is in the note. And the database is yours.
Checks before you call it done
Confirm this before you call the change done: The user is written. The privilege is written. Broad grants are written or absent. Nothing was granted. And the database is yours. If one of those fails, stop.
-- One privilege. SELECT is the starter.
-- Do not run GRANT during the reading.
-- Do not grant every privilege.Before you leave the database
Database User and Role Management ends when the database in the prompt is the database in the ticket. If it is not, you are on the wrong database. Stop.
The draft stays a draft until a person has read the names in it. A generator does not log into the database. You delete a line that names a host, a database, or an account you did not write down.
192.0.2.10, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. They belong in the note. They are not values you leave on a database because a draft included them.
prompt-for-this is a reminder that a secret is missing. It is not a password, a key, or a token you save in the ticket or in git. A sample password in a draft is replaced. It is not a password you keep.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the database name and the change aloud. If they cannot find them in the ticket, the note is not done.
This page is a planning guide. It is not a vendor manual, not an official standard, and not permission to touch a database you do not administer. You do not disable authentication, a firewall, or TLS to make a check pass.
