優化SQL Server 2012查詢

Question

我有一個查詢運行了12個小時。

查詢並留下聯接5個表和報告一堆月度指標。下面是該查詢：

SELECT DATEPART(YYYY,Referral_dt) AS RefYear, DATEPART(MM,Referral_dt) AS RefMonth, 
     CASE 
      WHEN CAST(Referral_dt as date) BETWEEN '1/1/2013' AND '4/14/2013' THEN 'Q1' 
      WHEN CAST(Referral_dt as date) BETWEEN '4/15/2013' AND '7/14/2013' THEN 'Q2' 
      WHEN CAST(Referral_dt as date) BETWEEN '7/15/2013' AND '9/30/2013' THEN 'Q3' 
      WHEN CAST(Referral_dt as date) BETWEEN '10/1/2013' AND '12/31/2013' THEN 'Q4' 
      WHEN CAST(Referral_dt as date) BETWEEN '1/1/2014' AND '4/14/2014' THEN 'Q1'

      AND (crm.salesstatuscode <> 'DUPL' or crm.salesstatuscode is null) 
      AND crm.lead_source not in ('Test Lead', 'Bank Lead Placeholder') 
    group by DATEPART(YYYY,Referral_dt), DATEPART(MM,Referral_dt), crm.Referral_State, crm.salesstatuscode, crm.lead_source, mp.mcc_desc, 
    mp.mcc_industry, sr.manager_name, sr.payrollname, sr.region,sr.market, sr.saleschannel, Bk.SuperRegion_Name, Bk.Region_Name ,Bk.Division_Name,

     WHEN CAST(Referral_dt as date) BETWEEN '10/1/2014' AND '12/31/2014' THEN 'Q4' 
    ELSE 'X' END 

當我運行了完整的查詢如上，運行12小時。但是當我運行查詢1個月時，它運行8分鐘。所以我想運行每個月的查詢並追加到一個文件中。這應該使這個查詢在2-3小時內運行。

我可以使用union並複製代碼24次，但這似乎並不是最好的方式。有沒有更好的方法來做到這一點？

更新：我希望能夠每天運行此查詢來更新最新月份的數字。

通過你貼我想你已經丟失的連接謂詞，併產生一噸的中間行的執行計劃的外觀：

這裏稍微清理了同樣的查詢（ CTE而不是相關的子查詢，並用DATEPART（QUARTER）取代CASE語句），它可能會更容易地判斷您的缺失謂詞的位置：

mp as (SELECT p.merchant_id, CAST(p.proposal_create_dt as date) as Proposal_Date, m.mcc_desc, m.mcc_industry 
    from kaiserver.[dbKAI].[dbo].[proposals] p 
    left join m on p.mcc = m.mcc where datepart(yyyy,proposal_create_dt) in ('2013', '2014')), 
ac as (SELECT account_no, CAST(Account_Activate_dt as date) as Acct_Act_Date, signed_annual_volume, average_tkt

Answer 2

我認爲這會產生相同的輸出，它應該會更快。此外，您需要確保用於JOIN或WHERE子句中的每個字段都已編入索引。

SELECT 
    DATEPART(YYYY,Referral_dt) AS RefYear, DATEPART(MM,Referral_dt) AS RefMonth, 
    CASE 
     WHEN CAST(Referral_dt as date) BETWEEN '1/1/2013' AND '4/14/2013' THEN 'Q1' 
     WHEN CAST(Referral_dt as date) BETWEEN '4/15/2013' AND '7/14/2013' THEN 'Q2' 
     WHEN CAST(Referral_dt as date) BETWEEN '7/15/2013' AND '9/30/2013' THEN 'Q3' 
     WHEN CAST(Referral_dt as date) BETWEEN '10/1/2013' AND '12/31/2013' THEN 'Q4' 
     WHEN CAST(Referral_dt as date) BETWEEN '1/1/2014' AND '4/14/2014' THEN 'Q1' 
     WHEN CAST(Referral_dt as date) BETWEEN '4/15/2014' AND '7/14/2014' THEN 'Q2' 
     WHEN CAST(Referral_dt as date) BETWEEN '7/15/2014' AND '9/30/2014' THEN 'Q3' 
     WHEN CAST(Referral_dt as date) BETWEEN '10/1/2014' AND '12/31/2014' THEN 'Q4' 
    ELSE 'X' END as RefQtr,
