在WHILE / Loop內部運行查詢

Question

在這里需要幫助，得到一個查詢，該查詢計算每個成員的行數並將其通過電子郵件發送給他們。

因此，現在他們收到一封簡單的電子郵件，告訴他們有多少帖子，我已經找到了一種在主查詢中運行第二個查詢的方法（該方法會計算帖子表中的帖子，並根據其帳戶信息生成電子郵件另一個表）我們想要的是讓電子郵件也顯示每個帖子，我已經在第一個查詢中加入了表，但似乎找不到在while語句中運行第二個表的方法。

這是我們當前擁有的代碼。 任何幫助將不勝感激。

子選擇是您想要的。 就像是。

"SELECT p.tech, p.date, e.email, e.fullname, "
        . "COUNT( * ) AS record_count, "
        . "(SELECT COUNT(*) FROM Posts z WHERE z.author = e.tech) as post_count "
        . "FROM users_test AS e "
        . "JOIN sc AS p ON e.tech = p.tech "
        . "WHERE DATE = '%s' "
        . "GROUP BY p.tech, e.fullname, e.email, p.date"
