This has nothing to do with TP, it is a problem with SQL - you have grouped, and count counts the number of rows in each group...

You can use fetchSql to fetch the SQL, and then try to execute it in the database yourself.

should be 102 records that meet the conditions with 20 unique uids.

The above is the statistics problem of thinkphp. Is it a miracle or a problem with my code? . For more related content, please pay attention to the PHP Chinese website (www.php.cn)!
