Question

using PHP and MySQL

i have grabbed an array of facebook user ids from facebook.

Now i want to find the corresponding username in my application for this array.

Clearly in my application the user table contains unique username and unique fb_uid values.

my rudimentary understanding oof programming led me to 2 ways:

1) use a loop and run through the array of fb_uid and find the username one by one.

OR

2) create a monster query like select distinct(username) from users where fb_uid = value1 OR fb_uid = value2 …

so is there a better way out?

Thank you.

Answer 1

Use SQL’s IN operator instead:

select distinct(username) from users where fb_uid in (value1, value2, ...)
