I’m working on an existing database that has a table like the following:

Table Name: account_info
id
first_name
last_name
account_number
amount

Example data:
1, John, Smith, 1-271342, 600.00
2, Marty, Kent, 1-236342, 100.00
3, Bill, Jones, 1-174234, 350.00
etc.

I have another table that tracks when the ‘account_info‘ table above has been last updated:

Table Name: account_update_history
id
last_updated
agent_who_updated
account_info_id

Example data:
1, 2015-02-04 04:23:43, Jill Beth, 2
2, 2015-02-03 12:27:14, Jill Beth, 2
3, 2015-02-01 14:31:32, Jill Beth, 2
4, 2015-02-03 23:43:52, Bob Smith, 1
5, 2015-02-01 06:23:42, Bob Smith, 1
etc.

The ‘account_update_history’ table can have many entries depending upon how many times the ‘account_info’ table has been updated. Where each of these rows points back to an 'account_info' row from the first table

My question is, I want to pull data from the database daily but only if an ‘account_info’ row has been recently updated (like for instance, the last 24 hours). What’s the best way to do this efficiently? I have thousands of records to scan daily.
