逗號分割數據轉化為一對多數據
select * from sys_role_list where id in(select c from(with test as (select roleid c from sys_role_info where id=1)select substr(t.ca,instr(t.ca, ',', 1, c.lv) + 1,instr(t.ca, ',', 1, c.lv + 1) - (instr(t.ca, ',', 1, c.lv) + 1)) AS cfrom (select ',' || c || ',' AS ca,length(c || ',') - nvl(length(REPLACE(c, ',')), 0) AS cnt FROM test) t,(select LEVEL lv from dual CONNECT BY LEVEL <= 100) c where c.lv <= t.cnt ))

　　轉化為逗號分割數據

(select DoctID, deptname = (stuff((select ',' + deptname from HE_DoctDeptRelation inner join yb_deptdict on yb_deptdict.DeptID=HE_DoctDeptRelation.DeptID where DoctID = a.DoctID for xml path('')),1,1,'')) from HE_DoctDeptRelation a group by DoctID) as DoctDept
