There, I explain a way you can get that you want.

Any doubt, just write me.

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:

http://firebird21.wordpress.com/2013/11/24/convirtiendo-filas-en-columnas/

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.

Hi Bhavbhuti!

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,
Set

Thanking you.
