Oracle】虚表的使用,主要结构是:
WITH 表昵称 AS ( SELECT … UNION ALL SELECT … )

其中UNION ALL是合并SELECT的结果集,需要注意的是,UNION 内部的 SELECT 语句必须拥有相同数量的列。列也必须拥有相似的数据类型。
(默认地,UNION 操作符选取不同的值。如果允许合并集中存在重复的值,请使用 UNION ALL。)

WITH DISPUTE_BI AS (SELECT '0' COUNT_TYPE, X.INFO_ORG_CODE,
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 = '27' THEN 1 ELSE NULL END),0) NCJT_TOTAL,--农村集体土地征用、流转
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 = '10' THEN 1 ELSE NULL END),0) GYTD_TOTAL,-- 国有土地上房屋拆迁
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 = '04' THEN 1 ELSE NULL END),0) CXJS_TOTAL,--城乡建设管理
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 = '18' THEN 1 ELSE NULL END),0) ZYQS_TOTAL,--土地、山林、水利、资源权属
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 = '03' THEN 1 ELSE NULL END),0) HJBH_TOTAL,--环境保护
       NVL(COUNT(CASE WHEN S.DISPUTE_TYPE_2 IN ('13','14','20') THEN 1 ELSE NULL END),0) CWGL_TOTAL,--村务管理
