Thanks Walter. I was hoping to get the columns appear on their own rather than individually predicting them (but if that is not at all possible well). I did have a look at your link and also the ones for Cross-Tab which was more nearer to what I wanted. Please see my present actual query and it's result
SELECT r.IPID, m.IID, m.CCODE, r.BAMT
FROM SSALEINVOICEFOOTER r
JOIN MACCOUNTS m
on m.IID = r.IACCOUNTID
ORDER by r.IPID
8 12 SALE 25000.000000
8 64 CENVAT 3000.000000
8 65 ECESS 60.000000
8 66 SHCESS 3000.000000
8 21 31060.000000
8 60 ST 1242.400000
8 63 ADDLVAT 310.600000
8 121 ST 32613.000000
16 12 SALE 3958.420000
16 587 EXP 3958.420000
17 12 SALE 148000.000000
17 588 148000.000000
20 12 SALE 27072.000000
20 64 CENVAT 3248.640000
20 65 ECESS 64.970000
20 66 SHCESS 32.490000
What I need to do is convert the above data based on the first column r.iPID being rows. m.cCODE being the column header and r.bAMT being the values for each column. This is what is the end result I was looking towards. Please note ST column for row iPID = 8 is a sum total of two ST cCodes in the same iPID
iPID, SALE, CENVAT, ECESS, SHCESS, ST, ADDLVAT, EXP
8, 25000.000000, 3000.000000, 60.000000, 3000.000000, 33855.400000, 310.600000, NULL
16, 3958.420000, NULL, NULL, NULL, NULL, NULL, 3958.420000
17, 148000.000000, NULL, NULL, NULL, NULL, NULL, NULL
20, 27072.000000, 3248.640000, 64.970000, 32.490000, NULL, NULL, NULL
Please advise
Thanks and regards

Well, it is not complicated at all, I was waiting for somebody writing a better technique but the days go on and that not happen then I show you a link to a page where the technique is described, with two examples. The page is in Spanish but you can use some translator (Google has one). And of course, if you have any question, just tell me, here or in the page:
One drawback of the technique is that you need to know in advance the exact number of columns or at least the maximum number of columns.
Greetings.
Walter.

SQL - at least the way Firebird implements it - is basically lousy at turning rows into columns, this is work more suitable for something like Excel (PivotTable), FastReport or some other tools/components. I think it is doable in Firebird using EXECUTE STATEMENT inside EXECUTE BLOCK, but it sounds more complicated than the alternatives mentioned above. I think one of the reasons for this being complicated to do in SQL, is that you normally need to know the number and type of columns in advance.
Sorry,
