MySQL-计算结果并以降序显示

Question

I want to query the table to get every referer and count duplicates and display each unique referrer and the number of times each unique referrer is recorded in the table. I'm a beginner with sql and php so any help in the right direction would be great :)

$ref=$icdb->get_row("SELECT * FROM url_log WHERE u = '".$dom."'");

Answer 1

I recommend you run & customise the query in a mysql tool like phpMyAdmin , or HeidiSQL (great freeware tools) to see the results it gives.

It's difficult to give a precise answer without knowing what fields are in your table, but you could try;

SELECT u, COUNT(*) AS c FROM url_log GROUP BY u
