IP を記録した訪問者のリストがあります。ここで特定のレポートを作成するために、各訪問者がどの国から来たかを確認する必要があります。
このタスクを 2 つの部分に分けました。最初に一意にログインしたユーザーのすべての IP を取得し、2 つ目の部分で国/IP 情報 (ip2nation から) を含む 2 つのテーブルを検索し、提供された IP で国を取得します。
最初の部分 - 一意にログインしたユーザーのすべての IP を取得する
SELECT
a.uid, a.hostname, a.timestamp,
COUNT(*) AS times
FROM
login_activity a
GROUP BY
a.hostname
ORDER BY
times desc
これにより、過去にログインしたすべてのユーザーの IP (ホスト名) が得られました。正常に動作します。
第 2 部 - IP を入力して、2 つのテーブル (両方とも数千のレコードがある) から国を取得します。
SELECT
c.country
FROM
ip2nationCountries c, ip2nation i
WHERE
i.ip < INET_ATON( "157.191.122.36" )
AND
c.code = i.country
ORDER BY i.ip DESC
LIMIT 0 , 1
これもうまくいきます。
さて、本当の問題です。これら 2 つのクエリを結合して、ログインしているすべてのユーザーから (IP ではなく) 国を取得します。これは私が書いたものです： -
SELECT
a.uid, a.hostname, a.timestamp, c.country,
COUNT(*) AS times
FROM
login_activity a, ip2nationCountries c, ip2nation i
WHERE
i.ip < INET_ATON(a.hostname)
AND c.code = i.country
GROUP BY
a.hostname
ORDER BY
times desc;
これには 2 つの問題があります。
- 読み込みに時間がかかります。
- 間違ったデータが返されます (各行の訪問数が千単位で表示されます)。
- 基本的に、すべてのデータが間違って表示されます。
この SQL を作成するのを手伝ってくれませんか?
念のため、テーブルの構造/データは以下のとおりです:-
