No doubt, they need to add support union in query builder. It will save our time and with the help of this builder we can design our website https://www.uniprint.net/en/vdi-printing/ more easily.

please support union in query bulder

This surely is a must have feature, why make it hard for complex queries to be designed, you have the awesome ability to do sub queries, this would just add the icing on the cake

This would be very handy as I sometimes have UNION in a subquery so the whole query cannot be easily split into blocks that will be editable in Query builder.

Example :

Create or Replace View SIQ_V_FINISHED_GOODS_SUM
as Select nvl(ALLOCATED.PFC_PRODUCT, INVENTORY.PFC_PRODUCT) PFC_PRODUCT,
ALLOCATED.WEIGHT ALLOCATED_WEIGHT, INVENTORY.WEIGHT INVENTORY_WEIGHT
From (Select PFCF101.PFC_PRODUCT, sum(PFCF101.PFC_QTY_TO_SHIP * PFCF101.PFC_WEIGHT) WEIGHT
From SIQRMS_PFCF100 PFCF100
INNER JOIN SIQRMS_PFCF101 PFCF101 ON PFCF100.PFC_BO_SEQUENCE = PFCF101.PFC_BO_SEQUENCE
AND PFCF100.PFC_ORDER_NO = PFCF101.PFC_ORDER_NO
Where PFCF100.PFC_ORDER_STATUS in ('1','2')
and PFCF100.PFC_ORDER_TYPE = '1'
Group By PFCF101.PFC_PRODUCT) ALLOCATED
Full Outer Join ( -- Inventaire Fil
Select PFCF001_FIL.PFC_PRODUCT,
sum(PROF413SIQ.PRO_ETIQUET_POIDS * PFCF001_FIL.PFC_WEIGHT) WEIGHT
From SIQRMS_PROF413SIQ PROF413SIQ
Inner Join SIQRMS_PROF400SIQ PROF400SIQ

Inner Join SIQRMS_PFCF001 PFCF001_FIL

Where ( PRO_ETIQ_DISPONIBILITE = ' '
or PRO_ETIQ_DISPONIBILITE = 'T')
And substr(PFCF001_FIL.PFC_PRODUCT,1,1) <> '1' -- Juste le fil
and PRO_ETIQ_ITEM_PERDU <> 'O'
