У меня есть запрос:

select cast (Stock as Varchar(63)) as VENSTGR,
cast(NULL AS Integer) as PRODUCTID,
cast(NULL AS Integer) as VENSTGRID,
cast(NULL AS Varchar(63)) as PN,
cast(NULL AS Varchar(255)) as PRODUCT,
cast(NULL AS Varchar(63)) as COMMENT,
si.quantity as STOCK,
cast(NULL AS Integer) as FORSALE,
cast(NULL AS Integer) as TRANZIT1,
cast(NULL AS Integer) as TRANZIT2,
cast(NULL AS Integer) as TRANZIT3,
cast(NULL AS Integer) as TRANZIT4,
cast(NULL AS Double Precision) as PRICE,
cast(NULL AS Double Precision) as OLDPRICE,
cast(NULL AS TimeStamp) as PRICEUPDATEDATE,
cast(NULL AS TimeStamp) as DATA
from Stock s,stockitem si where (s.stockid=6)
and (si.stockitemid=3164)
union all
select gr.VenStGr, st.productid, st.venstgrid, st.PN,st.Product,st.comment, st.stock, st.forsale,st.tranzit1,st.tranzit2,st.tranzit3,st.tranzit4,st.price,st.oldprice,st.priceupdatedate,gr.data from VENSTOCK st,VENSTGR gr
where st.VenStGrId=gr.VenStGrId
%cond

Работает нормально. Но, когда я добавляю выражение для сортировки:

select cast (Stock as Varchar(63)) as VENSTGR,
cast(NULL AS Integer) as PRODUCTID,
cast(NULL AS Integer) as VENSTGRID,
cast(NULL AS Varchar(63)) as PN,
cast(NULL AS Varchar(255)) as PRODUCT,
cast(NULL AS Varchar(63)) as COMMENT,
si.quantity as STOCK,
cast(NULL AS Integer) as FORSALE,
cast(NULL AS Integer) as TRANZIT1,
cast(NULL AS Integer) as TRANZIT2,
cast(NULL AS Integer) as TRANZIT3,
cast(NULL AS Integer) as TRANZIT4,
cast(NULL AS Double Precision) as PRICE,
cast(NULL AS Double Precision) as OLDPRICE,
cast(NULL AS TimeStamp) as PRICEUPDATEDATE,
cast(NULL AS TimeStamp) as DATA
from Stock s,stockitem si where (s.stockid=6)
and (si.stockitemid=3164)
union all
select gr.VenStGr, st.productid, st.venstgrid, st.PN,st.Product,st.comment, st.stock, st.forsale,st.tranzit1,st.tranzit2,st.tranzit3,st.tranzit4,st.price,st.oldprice,st.priceupdatedate,gr.data from VENSTOCK st,VENSTGR gr
where st.VenStGrId=gr.VenStGrId
%cond

order by st.STOCK desc,
st.TRANZIT1 desc,
st.TRANZIT2 desc,
st.TRANZIT3 desc,
st.TRANZIT4 desc


возникает ошибка:
Invalid ORDER BY clause. В чем причина?

Причина в том, что в случае с UNION в ORDER BY надо указывать не названия полей, а номера, т.е.: ORDER BY 7,9,10,11,12
