with compiere database i am trying ro show
between two dates.

The problem is (at least) in the group by
clause. Oracle does not allow column aliases in group by
. You can readily fix this with a subquery:
select t.*
from (select . . .
from . . .
where . . .
) t
group by . . .
order by . . . ;
In other words, put everything but the group by
and order by
in a subquery. Then put those clauses in the outer query.
You can't refer to a column alias in the same level of SQL, except in the order by
clause.
From the documentation (emphasis added):
You can use a column alias, c_alias, to label the immediately preceding expression in the select list so that the column is displayed with a new heading. The alias effectively renames the select list item for the duration of the query. The alias can be used in the
ORDER BY
clause, but not other clauses in the query.
When you refer to QTYLIV
in the GROUP BY
cluase the select list hasn't been evaluated yet and the alias doesn't exist. This is just how the query is parsed and executed.
When you have complicated expressions in the select list it's often simplest to wrap that in an outer select and do the grouping afterwards:
SELECT *
FROM (
SELECT p.name AS design,
p.M_PRODUCT_CATEGORY_ID,
il.PRICEACTUAL AS price,
bp.C_BPARTNER_ID AS idpartner,
CASE
...
(SELECT qtyinvoiced
FROM C_InvoiceLine il
WHERE bp.ISCUSTOMER ='Y'
AND bp.C_BPARTNER_ID= 18888
) AS qtyliv,
...
i.DATEINVOICED AS dat
FROM C_InvoiceLine il
INNER JOIN M_PRODUCT p
...
ON (oi.c_location_id=loc2.c_location_id)
--WHERE i.DateInvoiced BETWEEN $P{Date1} AND $P{Date2}
--AND
--i.DocStatus in ('CO','CL')
--AND i.IsSoTrx = 'Y'
--AND p.isstocked='Y'
)
GROUP BY name ,
M_PRODUCT_CATEGORY_ID,
QTYINVOICED,
PRICEACTUAL,
...
qtyliv,
qtydepot
ORDER BY name ,
dateinvoiced ;
Notice that you don't use the original table aliases in the GROUP BY
or ORDER BY
clauses in the outer select, as those are no longer in scope.
