Sql 需要帮助加速此查询吗

这是我的查询，获取50条记录大约需要5秒钟。以DB为单位的总行数约为100K

作为替代方案，我尝试使用此解决方案：

                    ELSE 0

但这仍然需要4秒以上的时间。理想情况下，我希望在1秒内得到结果。有没有办法加快速度？我已经在所有搜索列上建立了索引，其中包括辖区ID和DocumentStatusID-

杰出的你是机器吗？即使您没有任何DB表来实际测试查询，您是如何在没有语法错误的情况下发布答案的。@Devart:只是好奇您是如何将OP问题中第一个CTE中带有行数的案例转换为您编写的案例的？欢迎@Jack。不，我只是DevArt团队的DBA有什么原因必须在sp_executesql中？我看不出有任何要求。@praveen您能澄清一下您的问题吗？
