Question

Hello i’ve the following SQL query

 Select catalogid , numitems, allitems - numitems ignoreditems
        from ( 
        select i.catalogid,
         sum(case when (ocardtype in ('PayPal','Sofort') OR
                        ocardtype in ('mastercard','visa') and
                        odate is not null) then numitems
                        else 0 end) numitems,
         sum(numitems) allitems 
        from orders o
        join oitems i on i.orderid=o.orderid
        join products T1 on T1.catalogid = i.catalogid
        group by i.catalogid
        ) X 

in the last join statement table products contains 8 columns and they don’t show in the result query, i can only see the columns catalogid, numitems and ignoreditems, so what am i doing wrong, if i have to select those columns in order to make them appear how can i do it with this syntax?

Select catalogid , numitems, allitems - numitems ignoreditems, X.c1,X.c2,X.c3,X.c4,X.c5,X.c6,X.c7,X.c8
    from ( 
    select i.catalogid,
     sum(case when (ocardtype in ('PayPal','Sofort') OR
                    ocardtype in ('mastercard','visa') and
                    odate is not null) then numitems
                    else 0 end) numitems,
     sum(numitems) allitems ,
     T1.c1, T1.c2, T1.c3, T1.c4, T1.c5, T1.c6, T1.c7, T1.c8
    from orders o
    join oitems i on i.orderid=o.orderid
    join products T1 on T1.catalogid = i.catalogid
    group by i.catalogid, T1.c1, T1.c2, T1.c3, T1.c4, T1.c5, T1.c6, T1.c7, T1.c8
    ) X
