Record Plus record in access query

[Xuehong]

In My query, there are record

Dates Model Line Qty
2008/9/1 A LA 8
2008/9/2 A LA 2
2008/9/3 A LA 3
2008/9/4 A LA 5

I want to result to be:
Dates Model Line Qty
2008/9/1 A LA 8
2008/9/2 A LA 10
2008/9/3 A LA 13
2008/9/4 A LA 18

Means, for the records, if model and line is the same, Sum all the qty when
the date is <= current record's date,
Thank you,

i resolved it and want to have a sharing,
if my query name is Qrymain, then copy the query to another one qrymain1
then use this sentence:

SELECT Qrymain.*, (select sum(qty) from Qrymain where
Qrymain1.dates>=Qrymain.dates and Qrymain1.model=Qrymain.model and
Qrymain1.line=Qrymain.line) AS Sumaccqty
FROM Qrymain1;

There is no real reason to make a copy of the query. You can use two
instances of one query - simply assign a new name (alias) to the second
instance of the query.

SELECT QryMain.*
, (SELECT Sum(qty) FROM QryMain as Temp
Temp.Dates <= QryMain.Dates And
Temp.Model = QryMain.Model And
Temp.Line = qryMain.Line) as SumAccQty
FROM QryMain

Hi, John,
I have another question,if i do like this, then when i use this query to
generate a crosstab query,it will pop up error,".....doesn't recognize the
qrymain.dates as a valid field name......", so could you point me what can i
do if i want to geneate a crosstab base on such queries?

Please copy and post the SQL of your non-working query.

(Possibly unneeded instructions follow)
Open the query
Select View:Sql from the Menu
Select all the text
Copy it
Paste it into the message

Hi, John, first, thanks for your concern,
my first query sql is (which works well),named qryaccmain:

SELECT qrymain.*, (select sum(actqty) from qrymain as temp where
temp.dates<=qrymain.dates and temp.line=qrymain.line and
temp.project=qrymain.project) AS accqty
FROM qrymain;

when i use this query to generate a crosstab, the error pop up,the crosstab
sql as below:

TRANSFORM Sum(qryaccmain.accqty) AS SumOfaccqty
SELECT qryaccmain.Line, qryaccmain.Project
FROM qryaccmain
GROUP BY qryaccmain.Line, qryaccmain.Project
PIVOT qryaccmain.Dates;

 

[John Spencer]

Strange.

As a test, I guess I would try listing the required field names in the select
clause of qryAccMain.

SELECT qryMain.Line, qryMain.Dates, qryMain.Project
, (select sum(actqty) from qrymain as temp where
temp.dates<=qrymain.dates and temp.line=qrymain.line and
temp.project=qrymain.project) AS accqty
FROM qrymain;

What is in qryMain? Does it use any parameters?

No, Never used, it is only a summary query base on a simple table, i think
the problem is that we use a where condition "where

temp.dates<=qrymain.dates and temp.line=qrymain.line and
temp.project=qrymain.project", if i remove this condition it works, but the result is not what i want,

Thanks,
