You know what you want, just ask the database for it. There are several ways to query the database and i'll let you pick your favorite, but your sql query will be something like:

Code: Select all

SELECT id from table where name='Whatshis Face'

Where whatshis face is the name of the person whose id you want returned.

I'm sorry if i'm not understanding, but I think what you're looking for is ORDER BY. so your query (assuming you're doing a select all, would be like:

Code: Select all

SELECT * FROM table WHERE condition=true ORDER BY id ASC
