次のクエリでは、count2 の正しい値を返すときに問題が発生しています。

必要なのは、派生テーブル t を使用して簡単に実行できる table2 から行数を取得することです。

SELECT name, 
(SELECT COUNT(*) FROM `table1`) AS count1,
(SELECT COUNT(*) FROM (
    SELECT COUNT(*) FROM `table2` t2) WHERE t2.user = prf.user)
) t AS count2,
(SELECT SUM(a) FROM `table3`) AS count3
FROM `profiles` prf
WHERE 1=1
AND prf.user = 1

問題は、prf テーブルがサブクエリのスコープ外にあるため、WHERE t2.user = prf.user ステートメントが失敗することです。

上記を達成するにはどうすればよいですか？

編集:よりよく理解するのに役立つ場合に備えて、実際のクエリを追加しています:

SELECT PRF.BranchID, PRF.user_id, CONCAT_WS(" ",PRF.lastname,PRF.firstname) Synergatis, 
( SELECT COUNT(*) FROM Actions A JOIN Requests R ON R.RequestID=A.RequestID WHERE A.ActionStatus = 302 AND A.UserOwner = PRF.user_id AND A.ActionDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS energeies, 
( SELECT COUNT(DISTINCT RPP.RequestID) FROM VW_Xartofylakio_Synergati VV JOIN Requests_Prop RPP ON RPP.PropertyID = VV.PropertyID JOIN Requests R ON R.RequestID = RPP.RequestID WHERE VV.CurrUsr = PRF.user_id AND R.ModifyTime BETWEEN '2015-06-01' AND '2015-06-10' ) AS zitiseis_eidikes, 
( SELECT COUNT(DISTINCT(CustomerID)) FROM Demo_Orders_M WHERE DemoOrderStatus=253 AND USER=PRF.user_id AND DemoOrderDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS endiaferomenoi, 
( SELECT COUNT(*) AS cnt FROM Demo_Orders_M DOM JOIN Actions A ON DOM.DemoOrderID = A.DemoOrderID WHERE DOM.User = PRF.user_id AND DOM.DemoOrderStatus = 253 AND A.ActionDate BETWEEN '2015-06-01 14:56:19' AND '2015-06-30 14:56:19' GROUP BY DOM.CustomerID, DOM.User HAVING COUNT(*) > 1 ) AS anakykl_endiaf, 
( SELECT COUNT(*) FROM Demo_Orders_M DOM WHERE DOM.`User`=PRF.user_id AND DemoOrderStatus = 253 AND DOM.DemoOrderDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS epideixeis, 
( SELECT COUNT(DISTINCT(DOD.PropertyID)) AS PropertyID FROM Demo_Orders_M DOM JOIN Demo_Orders_D DOD ON DOM.DemoOrderID = DOD.DemoOrderID JOIN Actions A ON DOD.DemoOrderID = A.DemoOrderID WHERE DOM.DemoOrderStatus = 253 AND DOM.User = PRF.user_id AND A.ActionDate BETWEEN '2015-06-01' AND '2015-06-10' ) AS monadika_akinita
FROM tbl_profiles PRF 
WHERE 1=1 
AND PRF.user_id IN (
    SELECT a.user_id FROM tbl_profiles a WHERE a.user_id IN ('248','1159','486','183') 
    OR a.GroupID IN (SELECT b.GroupID FROM L_Groups b WHERE b.ManagerID IN ('248','1159','486','183')) 
    ) 
ORDER BY PRF.user_id

私が参照しているサブクエリは、anakykl_endiaf として結果を返すものです。

試してみる提案。

SELECT にサブクエリがあり、この場合、それぞれが 1 つの行のみを返す必要があります。なんらかの理由で (テスト データがないと実際にはわかりません)、これらの 1 つが複数の行を返しているため、失敗しています。

暫定的な手順として、サブクエリに対して結合するようにクエリを変更します。これにより、重複がある場合に、より明確になります (また、データによっては、かなり効率的になる場合もあります)。

このようなもの（テストされていないため、おそらくいくつかのタイプミスがあります）：-

anakykl_endiaf フィールドでユーザーの customerID フィールドの数をカウントするだけの場合は、個別の customerID のカウントを行うように変更します。つまり、上記のクエリの場合、次のように変更します。

LEFT OUTER JOIN
( 
    SELECT DOM.`User` AS DomUser, COUNT(DISTINCT DOM.CustomerID) AS anakykl_endiaf 
    FROM Demo_Orders_M DOM 
    JOIN Actions A ON DOM.DemoOrderID = A.DemoOrderID 
    WHERE DOM.DemoOrderStatus = 253 
    AND A.ActionDate BETWEEN '2015-06-01 14:56:19' AND '2015-06-30 14:56:19' 
    GROUP BY DOM.DomUser 
    HAVING COUNT(*) > 1 
) ae
