如何显示表中的固定条目数

Question

I have a table with 100+ entries, I want to display fixed number of entries from this table randomly.

I am using the query below.

SELECT * FROM Table1 WHERE active='1' AND id NOT IN 
(SELECT ad_id FROM Table1_logs WHERE uid='$username') ORDER BY RAND() LIMIT 5

Table1 contain all the entries, Table1_logs contains the entries which have been utilized by users today.

Problem:

I need to pick 5 entries daily for each users and should not exceed that amount. when a user utilizes one entry and it is saved in logs, query picks again 5 entries and it remains 5 all the time.

What I want to acheieve:

When a user utilizes one entry, it count should decrease. He should be able to see only 5 entries daily.

Answer 1

You should add a new field to table1 "utilizationCount" . When a link is utilized, you increase the value by one. And in the query, you should order by this field: " order by utilizationCount asc limit 5" .
