Question

我正在调整以下SQL查询

    SELECT C.zoneId                  ,
       Count(DISTINCT J.id)      ,
       Sum(BP.InstalledSubtotal)

GROUP  BY C.zoneId

请参阅执行计划。

有一个索引扫描。我不知道如何将其改为索引搜索。

我尝试了如下所示的提示。

with (forceseek)

但是当我将普通SQL和SQL的结果与提示进行比较时。正常SQL比带有提示的SQL表现更好。

请提供任何即兴查询的建议。目前它花了大约5至6秒。我试图把它减少到1-2秒。

@Devart：我已经实现了你的解决方案，但似乎执行时间相同。

请按照要求检查执行计划。
