比如我们的组织机构里面有很多下级机构及部门,要查询出登录人所在的机构,并列出该机构下所有机构和部门。Sqlserver写法如下:
with NewTable as ( select a.dept_id,a.dept_name,a.upper_id,a.tree_code,a.extend_type,a.DEPT_LEVEL,a.SORT_ORDER from SA_DEPT_DICT a where a.DEPT_ID=登录用户的部门ID union all select b.dept_id,b.dept_name,b.upper_id,b.tree_code,b.extend_type,b.DEPT_LEVEL,b.SORT_ORDER from SA_DEPT_DICT b inner join NewTable c on b.DEPT_ID=c.UPPER_ID where b.dept_TYPE=2 or b.DEPT_TYPE=6 ) , NewTable1 as ( select a.dept_id,a.dept_name,a.upper_id,a.tree_code,a.extend_type,a.DEPT_LEVEL,a.SORT_ORDER from SA_DEPT_DICT a , (select right(MAX(tree_code),4) dept_ID from NewTable where EXTEND_TYPE='机构' ) c where a.DEPT_ID=c.dept_ID union all select b.dept_id,b.dept_name,b.upper_id,b.tree_code,b.extend_type,b.DEPT_LEVEL,b.SORT_ORDER from SA_DEPT_DICT b inner join NewTable1 c on c.DEPT_ID=b.UPPER_ID where b.dept_TYPE=2 or b.DEPT_TYPE=6 ) select DEPT_ID,DEPT_NAME,UPPER_ID,SORT_ORDER,EXTEND_TYPE,TREE_CODE from NewTable1
