sql - MySQL: ID that has a pattern (primary key) -


i want have userid has pattern. instead of having id of 0, 1, 2.. etc, want adm-001, adm-002.

what best way achieve this?

i have absolutely no idea can't provide anything.

i aware not code writing site, suggestions appreciated.

thank in advance. :( :)

don't mess pk data itself; that's not purpose of pks. kill performance , pain manage.

just format on client, or in select query:

select ('adm' + lpad(id, 3, '0')) formattedid table;
