6 rows selected.i want Query No.2 to be exactly returning the same number of rows, like Query No.1 - 8 Rows.
for example, in Query 1, there are 2 rows returned for product code P01033691.5 & P01033691.7,
whereas in Query 2 they are shown on single rows.
This is not the only case, the situaton may change where there can be more than 2 or just 1 values (in this case 11,12)
for SALEVH_DO_REF_NO Col. in Query 2.
i want to always break Col-to-Rows for Query 2,
based on the DOD_PROD_CODE & DOD_DOH_NO of Query 1 matching with SALEVD_PROD_CODE, SALEVH_DO_REF_NO of Query 2 .
so that it will become easier finally to use MINUS between both Queries like this;
Query 3
SELECT CUST_NAME, DOD_PROD_CODE, to_char(DOD_DOH_NO,999999) DOD_DOH_no,
to_char(DOH_SO_REF_NO,999999) DOH_SO_REF_NO
FROM DELIVERY_ORDER_HEADER, DELIVERY_ORDER_DETAIL, CUSTOMER_MASTER
WHERE DOH_NO = DOD_DOH_NO
AND DOH_PARTY_CODE = CUST_CODE
AND DOH_SO_REF_NO = 13
MINUS
SELECT CUST_NAME, SALEVD_PROD_CODE, SALEVH_DO_REF_NO,
to_char(SALEVH_SO_REF_NO,999999) SALEVH_SO_REF_NO
FROM SALES_INVOICE_HEADER, SALES_INVOICE_DETAIL,CUSTOMER_MASTER
WHERE SALEVH_NO = SALEVD_SALEVH_NO
AND SALEVH_PARTY_CODE = CUST_CODE
AND SALEVH_SO_REF_NO = 13as per the above data the Query3 should not return any rows, but lets say a row gets added to Query 1 result,
i mean a new DOD_DOH_NO for the same DOH_SO_REF_NO. a 9th row for example;
ENERGY P01400012 13 13
and theres is no Invoice done, then Query 3 should return just 1 row which is just the above 1, the 9th row.
any help will be highly appreciated. TY

Answer 1

Mr. Massimo,
Your Query MUST return rows and those should be the following 8 rows;
CUST_NAME  SALEVD_PROD_COD SALEVH_ SALEVH_
ENERGY     P01033691.1          11      13
ENERGY     P01033691.5          11      13
ENERGY     P01033691.7          11      13
ENERGY     P01400012            11      13
ENERGY     P0140000014          11      13
ENERGY     P01033691.5          12      13
ENERGY     P01033691.7          12      13
ENERGY     P01033691.8          12      13
8 rows selected.
Your Latest Query returned no rows at all;
SCOTT@orcl>SELECT CUST_NAME, DOD_PROD_CODE, to_char(DOD_DOH_NO,999999) DOD_DOH_no,
  2  to_char(DOH_SO_REF_NO,999999) DOH_SO_REF_NO

  6  AND 0 = (select count(0) FROM SALES_INVOICE_HEADER, SALES_INVOICE_DETAIL,CUSTOMER_MASTER c2
  7  WHERE SALEVH_NO = SALEVD_SALEVH_NO
  8  AND SALEVH_PARTY_CODE = CUST_CODE
  9  AND SALEVH_SO_REF_NO = DOH_SO_REF_NO
10  AND c2.CUST_NAME=c.CUST_NAME
11  AND SALEVD_PROD_CODE = DOD_PROD_CODE
12  AND regexp_like(SALEVH_DO_REF_NO ,'(^|,)'||to_char(DOD_DOH_NO,999999)||'(,|$)')
13  AND to_char(SALEVH_SO_REF_NO,999999) = to_char(DOH_SO_REF_NO,999999))
14  AND 0 < (select count(0) FROM SALES_INVOICE_HEADER, SALES_INVOICE_DETAIL

17  AND regexp_like(SALEVH_DO_REF_NO ,'(^|,)'||to_char(DOD_DOH_NO,999999)||'(,|$)'));
no rows selectedi will rephrase and putting my case again. i am sure this time you;ll have better grasp on it.
These are the records for Items actually Delivered,columns are;

Query No. 2
The following are the Invoice issued for the Items Delivered above.
Not all Invoices have been issued, still left, are for DOD_DOH_NO 9 & 13.
The columns are ;
Customer Name                 = CUST_NAME        
Item Code                     = SALEVD_PROD_CODE 
Invoice Deliver Order Ref.No. = SALEVH_DO_REF_NO  (VARCHAR2)
Sales Order Ref. No.          = SALEVH_SO_REF_NO

6 rows selected.
Note: SALEVH_DO_REF_NO is VARCHAR2 field, that i have used save DOD_DOH_NO (type NUMBER) values,
in comma separated manner, offering user to club more than 1 Delivery Orders on a single Invoice.
Therefore i want a query that will turn Query2 result to something like;
CUST_NAME  SALEVD_PROD_COD SALEVH_ SALEVH_
ENERGY     P01033691.1          11      13
ENERGY     P01033691.5          11      13
