Help greatly appreciated with formatting a SQL Query

I need to select from an ARDOC table  Credit Memo documents that are older than the oldest Invoice in the same table.
Both of which have a DOCBAL<>0 and for the same CUSTID.

I am basically identifying Credit Memos with DOCBAL <>0 that are older than the oldest Invoice with a  DOCBAL <>0 within a CUSTID.

One document per row in the table. Table Contains both CM and IN type entries.

Credit Memos are DOCTYPE='CM'
Invoices are DOCTYPE='IN'

Here are a couple of queries I have:

Your help in formatting these to yield the results is truly appreciated:

select CustId,RefNbr,DocType,DocDate,OrigDocAmt,DocBal
from ARDoc
where DocType = 'CM'
and DocBal<>0


select CustId,RefNbr,DocType,DocDate,OrigDocAmt,DocBal
from ARDoc
where DocType = 'IN'
and DocBal<>0

Do they share the same custid and refnbr?

If not what is shared between them.

One or 2 samples would help.

SELECT cm.CustId,cm.RefNbr,cm.DocType,cm.DocDate,cm.OrigDocAmt,cm.DocBal
FROM dbo.ARDoc cm
INNER JOIN (
    SELECT CustId,Max(DocDate) AS DocDate
    FROM dbo.ARDoc
    WHERE DocType = 'IN'
    AND DocBal<>0
    GROUP BY CustId
) AS [in] ON [in].CustId = cm.CustId AND cm.DocDate > [in].DocDate
WHERE cm.DocType = 'CM'
AND cm.DocBal<>0

CustId is what is shared.

ScottPletcher, I think we are close but not returning the correct data.

I am looking for the query to return just the highlighted in this scenario.

Credit Memo Doc date is older than oldest invoice date.

Again this is just a sample for 1 specific CustID. Many custid are found in the table for both CM and IN Doctypes

I prefer the first of these 2 options but both should work I think (assuming I understand the problem)
select
*
from (
        select
            *
            , min(case when doctype='CM' then docdate end) over(partition by custid) min_cm_date
        from @ARDoc D1
    ) d
where docdate < min_cm_date
;

select
*
from @ARDoc D1
    cross apply (
            select  min(docdate) as min_cm_date
            from @ARDoc D2
            where D1.custid = D2.custid
            and D2.doctype = 'CM'
            ) ca
where D1.docdate < ca.min_cm_date

Open in new window


declare @ARDoc table
    ([custid] varchar(7), [doctype] varchar(2), [refnbr] varchar(9), [docdate] datetime)
;
    
INSERT INTO @ARDoc
    ([custid], [doctype], [refnbr], [docdate])
VALUES
    ('PAR6554', 'IN', 'I00580234', '2016-01-20 00:00:00'),
    ('PAR6554', 'IN', 'I00582390', '2016-10-12 00:00:00'),
    ('PAR6554', 'IN', 'I00582391', '2016-10-12 00:00:00'),
    ('PAR6554', 'IN', 'I00582797', '2016-10-17 00:00:00'),

Hmm, I think it got it backwards, maybe this then:

SELECT cm.CustId,cm.RefNbr,cm.DocType,cm.DocDate,cm.OrigDocAmt,cm.DocBal
FROM dbo.ARDoc cm
INNER JOIN (
    SELECT CustId, MIN(DocDate) AS DocDate
    FROM dbo.ARDoc
    WHERE DocType = 'IN'
    AND DocBal<>0
    GROUP BY CustId
) AS [in] ON [in].CustId = cm.CustId AND cm.DocDate < [in].DocDate
WHERE cm.DocType = 'CM'
AND cm.DocBal<>0

is it the other way around?
SELECT * --cm.CustId,cm.RefNbr,cm.DocType,cm.DocDate,cm.OrigDocAmt,cm.DocBal
FROM @ARDoc cm
INNER JOIN (
    SELECT CustId, MIN(DocDate) AS DocDate
    FROM @ARDoc
    WHERE DocType = 'CM'
    --AND DocBal<>0
    GROUP BY CustId
) AS [in] ON [in].CustId = cm.CustId AND cm.DocDate < [in].DocDate
WHERE cm.DocType = 'IN'
--AND cm.DocBal<>0

Try.. Check for docBal..column

CREATE TABLE ARDoc
(
	 [custid] varchar(7)
	,[doctype] varchar(2)
	,[refnbr] varchar(9)
	,[docdate] datetime
	,[DocBal] INT
)

INSERT INTO ARDoc
    ([custid], [doctype], [refnbr], [docdate],[DocBal])
VALUES
    ('PAR6554', 'IN', 'I00580234', '2016-01-20 00:00:00',1.00),
    ('PAR6554', 'IN', 'I00582390', '2016-10-12 00:00:00',1.00),

Pawan:

The last column contains the docbal.

It would be create if we could query from ARDOC table where all docs are so we dont have to create a temp table.
