--用户表create table user_info ( u_id int primary key,--用户id u_name varchar2(20),--姓名 Department_id int ,--部门id Position_id int ,--职位id)--到账记录表create table user_yes_info( u_id int , fee float,--金额 theMonth varchar(10)--月份)--待发记录表create table user_waiting_info( u_id int , fee float,--金额 theMonth varchar(10)--月份)--部门表create table Department_info ( Department_id int primary key , Department_name varchar2(50))--职位表create table Position_info ( Position_id int primary key , Position_name varchar2(50))
最后要查出来的字段是：
(查出所有用户的，没有的为0
姓名，部门 ,职位 ,总金额累计，到账金额累计，待发金额累计,本月总金额，本月到账金额，本月待发金额
------解决方案--------------------
nvl(sum(fee),0)就ok了
------解决方案--------------------
试试下面的sql，测试过：
select
t.u_name,--姓名
t1.department_name,--部门
t2.position_name,--职位
t3.fee_yes, --到账金额累计
t4.fee_waiting,--待发金额累计
t5.fee_yes_month,--本月到账金额
t4.fee_waiting,--本月待发金额
t4.fee_waiting+t5.fee_yes_month as fee_month --本月总金额

left join Department_info t1 on t.department_id=t1.department_id

left join (

group by t.u_id
) t6 on t.u_id=t6.u_id
where 1=1
order by t.u_name,t1.department_name,t2.position_name

貌似我写的简单一点
select u_name as 姓名，department_name as 部门 ,position_name as 职位 ,
'请指明计算公式' as 总金额累计，incomeTotal as 到账金额累计，payTotal as 待发金额累计,
'请指明计算公式1' as 本月总金额，incomeTotalThis as 本月到账金额，payTotalThis as 本月待发金额
