问题

1.编写SQL语句，查询PIM_HEADERS表，符合日期在2011-03-01和2011-03-25之间的PI订单，显示订单号，创建日志，订单客户名称，订单业务员名称

select 
    t1.PI_NO,t1.CREATION_DATE,t2.CUSTOM_NAME,t3.USER_NAME
from (select 
        * 
       from PIM_HEADERS
       where CREATION_DATE between 
                 to_date('2011-03-01','yyyy-mm-dd')
             and
                  to_date('2011-03-25','yyyy-mm-dd')
        ) t1
   left join CTM_CUSTOMERS t2
        on t1.CUSTOMER_ID = t2.CUSTOMER_ID
   left join SM_USER t3
        on t1.OPERATOR_ID = t3.USER_ID

2.编写SQL语句，查询所有部门名称及其给部门的业务员的个数，部门在2011-01-01到2011-03-01之间创建的PI订单数

select t1._DEPARTMENT_NAME,count(t2.USER_NAME),count(t3.PI_NO)
from SM_DEPT t1
  left join SM_USER_DEPT t2
     on t1.dept_id = t2.dept_id
  left join (select 
              * 
             from PIM_HEADERS
             where CREATION_DATE between 
                       to_date('2011-01-01','yyyy-mm-dd')
                   and
                        to_date('2011-03-01','yyyy-mm-dd')
              ) t3
     on t2.user_id = t3.OPERATOR_ID    
group by t1.DEPT_ID

3.编写SQL语句，查询所有客户及其相关PI订单号，PI创建日期，PI订单相关业务员姓名及其业务所属部门名称

select
      t1.*,t2.PI_NO,t2.CREATION_DATE,t3.USER_NAME,t5.DEPARTMENT_NAME
from SM_CUSTOMERS t1
   left join PIM_HEADERS t2
     on t1.CUSTOER_ID = t2.CUSTOMER_ID
   left join SM_USER t3
     on t2.OPERATOR_ID = t3.user_id
   left join SM_USER_DEPT t4
     on t3.USER_ID = t4.USER_ID
   left join SM_DEPT t5
     on t4.DEPT_ID = t5.DEPT_ID

4.编写SQL语句，更新没有下过PI订单的客户名称的备注为“从未发生业务往来”

update CTM_CUSTOMERS t1 set COMMENTS = '从未反生业务往来'
 where not exists (
       select PI_NO from PIM_HEADERS t2
        where t2.CUSTOMER_ID = t1.CUSTOMER_ID
 ) ;
 commit;

5.编写SQL语句，查询所有客户名称及其所属城市，并按照城市名称降序，用户名称升序排序

select CUSTOM_NAME,CITY
 from CTM_CUSTOMERS
 order by city desc,CUSTOMER_NAME asc

6.编写SQL语句，查询出所有的客户的PI订单的下单金额，显示客户名称，订单币种，订单总数量及订单总额

select
       t2.CUSTOMER_NAME,t1.CURRENCY_CODE,t3.TOTAL,t4.TOTAL_MONEY
 from PIM_HEADERS t1
    left join CTM_CUSTOMERS t2
        on t1.CUSTOMER_ID = t2.CUSTOMER_ID
   left join (
        select PI_ID,sum(QUANTITY) TOTAL,sum(QUANTITY*PRICE) TOTAL_MONEY
        from PIM_LINES 
        group by PI_ID
        
        ) t3
        on t1.PI_ID = t3.PI_ID;

7.编写函数，函数需传入部门ID，返回结果部门对应所有业务员姓名连接起来，中间用逗号隔开

create or replace function getUserByDeptId
       ( dept_id number) return varchar2
 is
       res varchar2(200);
        cursor mycursor(did number) is
             select t2.CUSTOMER_NAME
             from (select * 
                  from SM_USER_DEPT
                  where dept_id = did
                  ) t1
               left join SM_USER t2
               on t1.USER_ID = t2.USER_ID ;
 
 
 begin
     for c_row in mycursor(dept_id) loop
         res := res ||','|| c_row
     end loop;
     return res;
 end;
