AW: SQL question

Hi,

If you are already on release V5R4, you may try something like this:

With x as (Select row_number() over(Partition by Invoice Order By Invoice,
Invoiceline) as Counter
Fld1a, Fld2a, ... FldNa, Fld1b, Fld2b, ... FldNB
from Table1 a join Table2 b on a.Key1 = b.Key1 ... A.KeyN =
b.KeyN
Where ....)
Select Fld1a, Fld2a, ... , case when Counter = 1 then SalesTax Else 0 End,

From x

Order By Invoice, Counter
;

May be there is a typo, I didn't try it out becaus I have currently no
access to an iSeries.

Mit freundlichen Grüßen / Best regards

Birgitta Hauser

Betreff: Re: SQL question


What happens is that the sales tax is coming from the second file as the
total actual amount for the invoice, but it should only show the first time
so that you can get a true total of sales tax. by joining conventionally it
does bring the 21.00 to each joined line which is not what is wanted.

Invoice #, Date, Inv.Line Invoice line Amt, Sales Tax
1234 010108 01 100.00
21.00
1234 010108 02 200.00
21.00
1234 010108 03 99.00
21.00

Maybe so - took only a cursory glance.

An option might be to use a Query Management form to get the summary lines -
not sure. It's not clear what he really meant!

Vern,

From what I understand he wants to produce a report...

Order 111 Total 105.34 Tax 13.25
Item 1 Total 1.25 Tax .06
Item 2 Total 1.25 Tax .06
...
Order 112 Total 175.34 Tax 18.35
Item 1 Total 1.25 Tax .06
Item 2 Total 1.25 Tax .06
...

Report Total 280.78 Tax 31.60

To do this, doing a join wouldn't be the best in my opinion... because
you'll be accessing the sales tax file multiple times when it should
only be done once when the order number changes. I believe that's what
he was asking to be able to do with SQL but it cannot be done.

You just have to be sure not to use the

select *

syntax - list the individual fields/columns instead. If the names
are the same in each file, qualify them with the file name or and
alias name for the file.

Even in Query/400 you could do field selection, which'd accomplish
the same thing.

If I understand correctly... you are not going to be able to do
what

you

want...

When you do a join, the secondary file will get joined to the
primary

file

where matches occur. So the sales tax you talk of will be joined
to

every

record. IMO, you should change your logic. First to get the sales

tax

for the whole order, then separately process the primary file you
speak

of.

HI I have 2 files that are to be joined. in the secondary file
there is a field that is used in the report but I only want to
show it one time. To clarify, I am showing the invoice number
and other details, while the sales tax field is in the second
file. I only wish to show this sales tax once per order for the
report and as wel to tally this sales tax field as well as other
fields.

I am unsure how to do this in SQL. In query the sales tax will
show each time.

I can always write an RPG program to do this but was looking for
the quicker method.

Thanks,
