Answer 1

在查询之前添加设置统计信息配置文件。然后，您可以看到执行时间最长的部分

SET STATISTICS PROFILE ON

SELECT * FROM [TABLE]

Answer 2

哇，有很多地方可以调整这个;让我们从使用NULL更改NOTFT到LEFT JOIN开始：

     q_01 AS ( SELECT    DIVISION
          , DYYYY
          , SUM(PARTY) AS YEPAX
          , SUM(NetAmount) AS YESales
          , SUM(OtherAmount) AS YEotherSales
  FROM      dbo.B101BookingsDetails
            INNER JOIN Years ON B101BookingsDetails.DYYYY = Years.Year
            LEFT JOIN dbo.regionexlude r ON SDESCR = r.columnname
  WHERE     r.columnname IS NULL
     /*where SDESCR not in (select * from dbo.regionexlude)*/
  GROUP BY  DIVISION
          , DYYYY
          , years.year
  HAVING    DYYYY = years.year  ),
