Hello experts,

I have this conditional join right here, thanks to the help of the community yesterday

INSERT INTO shipping(sdate, rec_wh, shipping, item)
    SELECT ship_date, receiver_warehouse, ord, custitemcode
      FROM wag
     WHERE     custitemcode = 'SOME ITEM'
           AND (SELECT SUM(ord)
                  FROM recinc
                 WHERE in_item = 'SOME ITEM') = (SELECT SUM("tSHIPPING")
                                                   FROM trans
                                                  WHERE "tITEM" = 'SOME ITEM');

Open in new window


While this achieves what I am trying to do when i use the variable 'SOME ITEM'

I need this to be accomplished on all items in that column that match the above statement. I have tried different variations of the above and it does not work


so lets say in columns, IN_ITEM and t_ITEM have 'SOME ITEM' and other items (eg, 'some item2' 'some item3' etc etc

i want this to happen to all rows where column data matches

I'm not really sure I follow what you're asking, but does the following work?  I replaced SOME ITEM, with a reference to CustItemCode, and removed that filter.  You also had quotes around field names, which I removed.

INSERT INTO shipping(sdate, rec_wh, shipping, item)
    SELECT ship_date, receiver_warehouse, ord, custitemcode
      FROM wag
           WHERE (SELECT SUM(ord)
                  FROM recinc
                 WHERE in_item = wag.custitemcode) = (SELECT SUM(tSHIPPING)
                                                   FROM trans
                                                  WHERE tITEM = wag.custitemcode);

tITEM and tSHIPPING are mixed case, you'll need to restore the quotes taken out above


SUM("tSHIPPING")

WHERE "tITEM" = wag.custitemcode);


otherwise oracle will treat them as columns with names TSHIPPING and TITEM which don't exist in your table


also note, if you still want to apply a filter to the wag table, then apply it there by adding a clause like this to end of the query...

AND wag.custitemcode in ('SOMEITEM','some_other_item','a_third_ITEM')
