   2.due to this it was impacting on DB performance.
   3.even for Explain plan also it was taking very long time.
   4.My query is very big.

Query:

(
    select paid.keyword_id, paid.keyword_name, stat.orgEntrances,
    keyword.rank1, keyword.rank_check, 
    SUM(paid.clicks) as sumclick, 
    SUM(paid.clicks * paid.avg_position) as sumclickavgpos,
    SUM(paid.itemRevenue) as sumitem,
    SUM(paid.cost) as sumcost,  
    SUM(paid.transactions) as sumtrans,  
    SUM(paid.impressions) as sumimpress,  
    IF(SUM(paid.impressions) = 0, 0,
        SUM(paid.impressions * paid.avg_position) / SUM(paid.impressions))  
    as sumimpressavgrank,
    con.item_revenue,  con.transactions,  keyword.monthly_search_volume

Please help me here.

Answer 1

Create index and change where condition. put (outer_t.medium = 'organic' or outer_t.medium is null ) after outer_t.own_domain_id = 720 and (paid.channel is null or paid.channel = 'Google') after paid.own_domain_id = 720. Try, i hope it will make your query faster.
