Mysql 受计数限制

Question

我目前有一个查询，我正在将其放在一起以查找输入的次数。我试图找出如何将这些条目限制为低于特定计数(< 4)的任何内容。

SELECT
    t.id `Ticket ID`,
    a.asset `Asset`,
    sol.solution `Solution reported`,
    COUNT(tjou.id) `Journal entry count`

FROM tickets t 
    JOIN assets a ON t.asset_id = a.id
    LEFT JOIN ticket_solutions tsol ON tsol.ticket_id = t.id
    JOIN solutions sol ON tsol.solution_id = sol.id
    JOIN ticket_journal tjou ON tjou.ticket_id = t.id
WHERE t.deleted IS FALSE
AND tjou.system_msg IS FALSE
AND DATE(t.close_dt) >= DATE_SUB(NOW(),INTERVAL 1 MONTH)
AND DATE(a.labor_w_end_dt) > CURDATE()
AND sol.solution != 'Communications Issue'
GROUP BY t.id
ORDER BY `Journal entry count` ASC

Answer 1

尝试追加这个

HAVING COUNT(tjou.id) < 4

在 GROUP BY 之后和 ORDER 语句之前
