尽量避免在SQL Server查询中使用UNION

我有一个查询，为呼叫中心收集不同的指标：

    SELECT      CONCAT (DEPARTMENT_DESC, 'Week', datepart(wk, ROW_DATE)) As Dept_Date,
            datepart(wk, ROW_DATE) as weeknum,
            DEPARTMENT_DESC AS DEPT,
            SUM([CALLS_OFFERED_ACTUALS]) As LCW_Calls_Offered,
            MAX(LCW) AS LCW,
            (SUM(ANSTIME) / SUM(CALLS_ANSWERED_ACTUALS)) AS ASA,
            SUM(HANDLED_TIME) / SUM(CALLS_ANSWERED_ACTUALS) AS AHT,
            SUM(HANDLED_TIME) as handletime,
            SUM(CALLS_OFFERED_FCST) AS Call_Target,
            SUM(CALLS_ANSWERED_ACTUALS) as call_answered,
            CAST(1.000*(SUM(TRANSFERS)+SUM(CONFERENCE)) / SUM(CALLS_ANSWERED_ACTUALS) AS DECIMAL(19,3)) AS Transf_Rate,
            CAST(1.000*(SUM(CALLS_ABD_ACTUALS)) / SUM([CALLS_OFFERED_ACTUALS]) AS DECIMAL(19,3)) AS Abandon_Rate,
            1-CAST(1.000*(SUM(LCW60)) / SUM(INT_CNT) AS DECIMAL(19,3)) AS LCW_INT,
            CAST(1.000*(SUM(ONLINETIME)-SUM(AVAILTIME)-SUM(ALARMTIME))/SUM(ONLINETIME)  AS DECIMAL(19,3)) AS Occupancy,
            CAST(1.000*(SUM(PRODTIME)) / SUM(ATWORKTIME) AS DECIMAL(19,3)) AS Productivity,
            CAST(1.000*(SUM(AVAILTIME)) / SUM(ATWORKTIME) AS DECIMAL(19,3)) AS Availab,
            CAST(1.000*(SUM(OVERTIME)) / SUM(WORKFORCETIME) AS DECIMAL(19,3)) AS Overtime,
            CAST(1.000*(SUM(UNPROD_TIME_UNPLANNED)) / SUM(WORKFORCETIME) AS DECIMAL(19,3)) AS Unplanned_Shrink,
            CAST(1.000*(SUM(UNPROD_TIME_PLANNED)) / SUM(WORKFORCETIME) AS DECIMAL(19,3)) AS Planned_Shrink,
            CAST(1.000*(SUM(CALLS_ANSWERED_INT1)+SUM(CALLS_ANSWERED_INT2)) / SUM(CALLS_OFFERED_ACTUALS) AS DECIMAL(19,3)) AS SL_Within_20,
            CAST(1.000*(SUM(CALLS_ANSWERED_INT1)+SUM(CALLS_ANSWERED_INT2)+SUM(CALLS_ANSWERED_INT3)+SUM(CALLS_ANSWERED_INT4)+SUM(CALLS_ANSWERED_INT5)+SUM(CALLS_ANSWERED_INT6)) / SUM(CALLS_OFFERED_ACTUALS) AS DECIMAL(19,3)) AS Calls_Within_60,
            1-CAST(1.000*(SUM(LCW300)) / SUM(INT_CNT) AS DECIMAL(19,3)) AS LCW_INT1,
            1-CAST(1.000*(SUM(LCW120)) / SUM(INT_CNT) AS DECIMAL(19,3)) AS LCW_INT2
      FROM [GEMDB].[dbo].[v_calls_LCW_Splitday]
  where datepart(wk, ROW_DATE) >= (datepart(wk, GETDATE()) - 6) AND datepart(year, ROW_DATE) = 2017
  GROUP BY datepart(wk, ROW_DATE), DEPARTMENT_DESC --((CALLS_ANSWERED_INT1 + CALLS_ANSWERED_INT2) / [CALLS_OFFERED_ACTUALS]) 
  ORDER BY datepart(wk, ROW_DATE

）

结果按周数和数字分组。部门（计费，技术支持，保留等）

我们决定创建一个名为客户服务的新子部门，该部门由Billing＆amp; amp;技术支持。

我找到了一种方法，通过对另一个只选择Billing＆amp;数据的数据的UNION执行UNION。技术支持。

这样运行正常，但查询从花费20秒到超过3分钟完成：

  SELECT *
  FROM #TEMP_ALL
  UNION
  SELECT *
  FROM #TEMP_CS

  DROP TABLE #TEMP_ALL
  DROP TABLE #TEMP_CS

有没有更有效的方法来实现这一目标？我们无法等待3分钟+以完成此查询。

谢谢！

1 个答案:

答案 0 :(得分：2)

  • 不确定为什么你需要临时表
  • 不确定为什么需要使用union vs union all
  • 为避免结合，为什么不使用案例陈述：case when DEPARTMENT_DESC in IN ('BILLING', 'TechOps') then 'Customer Service' else DEPARTMENT_DESC end

保持联合但使用union all并避开临时表。

现在没有工会，你只需要一个case语句用一个case

替换department_Desc 
case when DEPARTMENT_DESC in IN ('BILLING', 'TechOps')  
                then 'Customer Service' 
                else DEPARTMENT_DESC end

所以我接受了你的第一个询问并做了那件事。

SELECT CONCAT(case when DEPARTMENT_DESC in IN ('BILLING', 'TechOps')
