コードで発生する問題がありますが、phpmyadmin でクエリをテストすると、NULL(想定どおり) が表示されます。

いくつかのテーブルを結合して、ユーザーに関するすべての情報を表示したいと考えています。user テーブルには、クライアントに関する基本情報が含まれています。私のページでは、ユーザーの可能な医師の訪問、理学療法士の訪問、および専門家による治療に関する情報を追加したいと考えています。すべての接続は、次のように異なるテーブルに格納されます。


+------+-------------+--------------+
| n_id | n_client_id | n_connect_id |
+------+-------------+--------------+
|  1   |     1       |       1      |
+------+-------------+--------------+
|  2   |     1       |       2      |
+------+-------------+--------------+

n_connect_id一致するテーブルに格納されている医師の理学療法士および/または専門家の記録の ID のいずれかです。

すべてのユーザーが 3 つ (医師、理学療法士、および専門家) のテーブルすべてにレコードを持っているわけではないため、場合によってNULLは が出力されます。

phpmyadmin でクエリをテストすると$client = 1;、次の出力が得られます (医師の診察は にのみ適用されるため、これは正しいですclient_id 1)。

問題は行のどこかにあると思いLEFT JOIN adm_doctor_visit_records AS dvr ON dvr.dv_client_id = client.c_idます。これは、医師の診察記録を保存するテーブルであるためです。私は user_id だけで参加したと思っていましたが、どうやらここで何かがおかしいようです。

PS、私はOOPを始めたばかりなので、間違った方法で行っている場合、これが私が理解している方法です（ただし、提案は受け付けています）

ああ..それを解決しました、どういうわけかを介して間違ったパラメータを渡していました$client。しかし、それがどのように起こるのか奇妙です。助けてくれてありがとう！

GROUP_CONCAT を実行していますが、GROUP BY 句を指定していません。これは、奇妙な/間違った結果につながります。
