DB2学习

1.为了使用ORG_ID，由于OCRM_F_MM_MKT_PLAN a 没有ORG_ID，但是OCRM_F_MM_EXECUTE_INST_DESC d 表里面有，可以使a表连接b表，创建临时表t。

select t.PLAN_S  AS MARKET_PLAN_COUNT,t.SUM_PLAN AS PLAN_ACC_COUNT  
 from (select count(a.MKT_PLAN_STAT) as PLAN_S,sum(case when  a.MKT_PLAN_STAT='3' then 1 else 0 end) as SUM_PLAN from OCRM_F_MM_MKT_PLAN a left join OCRM_F_MM_EXECUTE_INST_DESC d on (d.PLAN_ID=a.PLAN_ID))t;

2.

select  f.ORG_ID,f.ORG_NAME,t.MARKET_PLAN_COUNT,t.PLAN_ACC_PER,t.PLAN_ACC_COUNT,
    b.MARKET_ACT_COUNT,b.ACT_ACC_COUNT,b.ACT_ACC_PER,c.OPPOR_COUNT,
    c.OPPOR_ACC_COUNT,c.OPPOR_ACC_PER
     from( select d.org_id,count(a.MKT_PLAN_STAT) as MARKET_PLAN_COUNT,
     sum(case when  a.MKT_PLAN_STAT='3' then 1 else 0 end)  as  PLAN_ACC_COUNT,
     ROUND(CAST(sum(case when  a.MKT_PLAN_STAT='3' then 1 else 0 end) AS DOUBLE) / count(a.MKT_PLAN_STAT)*100,4) as PLAN_ACC_PER
      from OCRM_F_MM_MKT_PLAN a left join OCRM_F_MM_EXECUTE_INST_DESC d on (d.PLAN_ID=a.PLAN_ID) group by org_id)t  
      left join (select CREATE_ORG,count( MKT_ACTI_STAT) as  MARKET_ACT_COUNT,sum(case when MKT_ACTI_STAT='4' then 1 else 0 end)  AS ACT_ACC_COUNT,
     ROUND( sum(case when MKT_ACTI_STAT='4' then 1 else 0 end)/count( MKT_ACTI_STAT)*100,4) as ACT_ACC_PER
       from OCRM_F_MK_MKT_ACTIVITY group by CREATE_ORG) b on (t.ORG_ID=b.CREATE_ORG)
       left join
        (
        select CREATE_ORG_ID, count(OPPOR_STAT) as OPPOR_COUNT,  sum(case when OPPOR_STAT=7 then 1 else 0 end)  + sum(case when OPPOR_STAT= 8  then 1 else 0 end)   AS OPPOR_ACC_COUNT,
      ROUND(CAST( ( sum(case when OPPOR_STAT=7 then 1 else 0 end)  + sum(case when OPPOR_STAT= 8  then 1 else 0 end)) AS DOUBLE)/count(OPPOR_STAT) *100,4)as OPPOR_ACC_PER  from OCRM_F_MM_MKT_BUSI_OPPOR group by CREATE_ORG_ID) c on (b.CREATE_ORG=c.CREATE_ORG_ID)
       left join ADMIN_AUTH_ORG f on (c.CREATE_ORG_ID=f.ORG_ID)

3.统计状态为3，3代表成功的，把3看做1，然后累加1，最后得到表里面有多少个3

select count(a.MKT_PLAN_STAT) as MARKET_PLAN_COUNT,  sum(case when  a.MKT_PLAN_STAT='3' then 1 else 0 end)  as  PLAN_ACC_COUNT from OCRM_F_MM_MKT_PLAN a;

4.统计查找客户经理名称，编号，这个客户经理营销计划数量，完成数量，完成率以及营销活动数量，完成数量，完成率以及商机数量，完成数量，完成率，以及这个客户经理的所属机构，机构号。
