最外层的from少一个（

------解决方案--------------------
你不都写出来了吗？
把你的CTE写成子查询就可以了

SQL code
with my1 as(select * from dept where dept_id = 1
 union all select dept.* from my1, dept where my1.dept_id = dept.p_dept_id
)
select * from (
select uml.NAME as '姓名',uml.dept_id as '部门',
Row_Number() over(order by name asc) RowNumber from userinfo uml, my1 um2 where uml.dept_id=um2.dept_id)temp1
 where RowNumber BETWEEN  1 and  5

a    1    1
c    3    2
d    4    3
f    6    4
