Subquery in load

[#1]

Hi,

I have a table account_invoice which contains all the invoices. I have to look for the invoices where free samples were given to the customers and if those customers later on bought more products by paying.

account_invoice:

Load "partner_id",

        "date_invoice",

          .....

          .....;

SQL Select  "partner_id",

                   "date_invoice",

                    .......

                    .......

From account_invoice;

Freesamples:

SELECT partner_id pid,

              date_invoice din

FROM account_invoice

WHERE UPPER(name) like '%SAMPLE%' and amount_untaxed = 0;

Converted:

Load partner_id,

        date_invoice

Resident account_invoice

where exists(pid,partner_id) and amount_untaxed <> 0;

How do i get the list of free sample customers and the converted customers? Should i use a left join or exists? Both dont give the correct resultset, it will be great if somebody could point out what is wrong in the above logic.

Thanks

Swetha

May be you can rather create a flag field like:

SQL Select  "partner_id",

                   "date_invoice",

                    .......

                    .......

From account_invoice;

Left Join

SELECT partner_id,

              date_invoice,

              If(UPPER(name) like '%SAMPLE%' and amount_untaxed = 0, 'Free Sample',

                    If(mount_untaxed=<>0, 'Converted', 'Others')) as CustomerType

FROM account_invoice;

And then use this CustomerType filed in the front-end for analysis.

tresesco   Thanks for the quick response. I have to find out how many of those free sample customers actually got converted. Hence the flagging logic may not work.

Please let me know if i am missing something here.

Thanks

But your conditions of amount_untaxed for both (=0 and <>0) are mutually exclusive, there can't be a common element. Not sure if I am missing some of your points.

          .....

          .....;

SQL Select  "partner_id",

                   "date_invoice",

                    .......

                    .......

From account_invoice;

Left Join(account_invoice);

SELECT partner_id

             IsFreeSampleCustomer

resident account_invoice

WHERE wildmatch(name, '*SAMPLE*')>0

From account_invoice;

Left Join(account_invoice);

SELECT partner_id

             IsUntaxedCustomer

resident account_invoice

WHERE  amount_untaxed = 0;

Thanks for your help . I was able to solve it using inline tables but your approach gave me ideas.

Thanks
