Question

找到相关的类型解决方案，但没有满足我的需求；我想用查询（pu_cnt，pu_ot，pu_ltc等）的结果更新现有的表记录（字段pu_cnt，pu_ot，pu_ltc等）。这是我的查询：

    SELECT 
    COUNT(CASE WHEN vuWO_CHC_ALL.status IN('C','D','H','F') THEN 1 END) AS 
    pu_cnt,
    COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actpu_delay_code,1) LIKE '' THEN 1 END) AS 
    pu_ot,
    COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actpu_delay_code,1) LIKE 'C' THEN 1 END) 
    AS pu_ltc,
    COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actpu_delay_code,1) LIKE 'U' THEN 1 END) 
    AS pu_ltu,
   COUNT(CASE WHEN vuWO_CHC_ALL.status IN('D','H','F') THEN 1 END) AS del_cnt,
   COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actdel_delay_code,1) LIKE '' THEN 1 END) AS 
   del_ot,
   COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actdel_delay_code,1) LIKE 'C' THEN 1 END) 
   AS del_ltc,
   COUNT(CASE WHEN LEFT(vuWO_CHC_ALL.actdel_delay_code,1) LIKE 'U' THEN 1 END) 
   AS del_ltu
   FROM vuWO_CHC_ALL WHERE
   RTRIM(vuWO_CHC_ALL.SHIPPER) LIKE @pVendor AND
   RTRIM(vuWO_CHC_ALL.ORIG) LIKE @pOrigin AND
   RTRIM(vuWO_CHC_ALL.Dest) LIKE @pDestin

..

使用@variables弄清楚。

使用多案例查询的结果更新单个记录
