我收到错误

insert into dmi_user.fct_sales_summary_cmp values SELECT  A.bio_id
                                                  *
ERROR at line 1:

在运行以下查询

insert into dmi_user.fct_sales_summary_cmp values SELECT  A.bio_id
,decode(A.wk_units2 - B.wk_units1,0,NULL,A.wk_units2), decode(A.wk_units2 -

A.wk_units4<> B.wk_units3 or  A.wk_units5<> B.wk_units4 or  A.wk_units6<>
B.wk_units5)

please let me know the issue with following script (sql,oracle 10g)

SELECT A.PD_END_DT Recent_PD_END_DT,

       wkly_lnd.lnd_wkly_plan_rx_summary B 
WHERE  a.MKT_I D =b.MKT_ID;

我们需要以这样一种方式实现以下查询:我们不应该编写这么大的查询,而应该通过过程,函数或匿名块来实现它(我们能做什么)

wk_units1-105是列名cnt_sls_dm.fct_sales_summary表名.我们正在比较同一个表中的数据,但a.fct_sales_summary的第2周与b.fct_sales_summary
的第1周进行比较

简而言之,我们需要在pl/sql中创建一些东西以应用以下功能(我是仪式)

SELECT  DISTINCT A.bio_id ,
    DECODE(A.wk_units2 - B.wk_units1,0,NULL,A.wk_units2) prev,
    DECODE(A.wk_units2 - B.wk_units1,0,NULL,B.wk_units1) curr, 
    DECODE(A.wk_units3 -B.wk_units2,0,NULL,A.wk_units3) prev, 
    DECODE(A.wk_units3 -B.wk_units2,0,NULL,B.wk_units2) curr, 
    DECODE(A.wk_units4 -B.wk_units3,0,NULL,A.wk_units4) prev,
