So I need to give a filter while loading QVD so it loads row1 and deletes row2& 3 and loads row4 and so on...

Can anyone let me know what is the filter we need to use while loading this QVD.

Thanks for any help!!

So, if I understand correctly you need to delete every second and third row?

If that's the case, you could load first the QVD then with NoConcatenate reload it from resident into a new table with a for loop; use a counter to avoid loading the second and third row; then drop the original table

LOAD *

FROM myqvd.qvd (qvd)

WHERE NOT Match(RecNo(), 2, 3);

Hi Rajender,

Try:

LOAD *

FROM myqvd.qvd (qvd)

WHERE Mod(RecNo()-1,3) = 0;

Hi Andrew,

Thanks for your reply.

Do you know how to load 2 rows and skip 5 rows and load 2 rows again and skip 5 rows and so on using QVD load.

Hi Rajender,

Consider this table:

RecNo()	Mod(RecNo()-1,7)
1	0
2	1
3	2
4	3
5	4
6	5
7	6
8	0
9	1
10	2
11	3
12	4
13	5
14	6
15	0
16	1
17	2
18	3
19	4
20	5

you'll see that the where clause to use is

WHERE Mod(RecNo()-1,7) <=1

Andrew
