감사합니다!

Answer 1

당신은 MySQL의에서 SET (a,b) = (value_a, value_b)를 가질 수 없습니다? 이것 좀 도와 줄래.

에서, Clicks_chg, AveragePosition_chg, Ctr_chg, AverageCpc_chg, 문헌 [Curr '

쿼리를 다시 작성하십시오. 다음과 같은 것 :

UPDATE 
    keywords_stats_google_temp AS u 
    JOIN 
    (SELECT 
      SUM(Impressions) AS Impressions, 
      SUM(Clicks) AS Clicks, 
      SUM(Impressions*AveragePosition)/SUM(Impressions) AS AveragePosition, 
      (SUM(Clicks)*revenue_price)/SUM(Impressions) AS Ctr, 
      SUM(Spend)/SUM(Clicks) AS AverageCpc, 
      CurrentMaxCpc, 
      SUM(free_joins) AS FreeJoins, 
      SUM(paid_joins) AS PaidJoins 
     FROM keywords_stats_google_naughtymeetings AS b 
     WHERE b.TimePeriod >= '2012-04-01 00:00:00' 
     AND b.TimePeriod <= '2012-04-23 00:00:00' 
     GROUP BY KeywordId, 
       MatchType 
    ) AS tmp 
     ON tmp.KeywordId = u.KeywordId 
     AND tmp.MatchType = u.MatchType 
SET 
    u.Impressions_chg  = tmp.Impressions, 
    u.Clicks_chg   = tmp.Clicks, 
    u.AveragePosition_chg = tmp.AveragePosition, 
    u.Ctr_chg    = tmp.Ctr, 
    u.AverageCpc_chg  = tmp.AverageCpc, 
    u.CurrentMaxCpc_chg = tmp.CurrentMaxCpc, 
    u.FreeJoins_chg  = tmp.FreeJoins, 
    u.PaidJoins_chg  = tmp.PaidJoins ;
