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
OFFSET skips rows. A keyset continues from the last key you name, and that key needs a stable order. The generator drafts both shapes. It does not run them.
Write the order column. Do not run either draft during the reading. One read, on a table you can name.
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 order column.
- Read the OFFSET sketch.
- Read the keyset sketch.
- Do not run either one.
- Stop.
Mistakes that outlive the statement
SQL Pagination: OFFSET vs Keyset goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A draft run during the reading.
- The order column left unnamed.
- A table you do not administer.
Decisions to write down
One decision for SQL Pagination: OFFSET vs Keyset: The order column is written. Both sketches were read. Nothing was run. And the database is yours.
Checks before you call it done
Confirm this before you call the change done: The order column is written. The chosen shape is written. Both sketches were read. Nothing was run. And the database is yours. If one of those fails, stop.
Before you leave the database
SQL Pagination: OFFSET vs Keyset 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.
