re: multiRow Fetch

Andrew,

I believe a MODS can be based therefore dynamic. However, no matter whether
I use a MODS or an ARRAY, I am not allocating the storage through the based
pointer.  If there are too rows returned, the FETCH fails. If too few, I
have unused elements.


Thanks,

Mark

I think you misunderstood me.

Correct me if I am wrong:

Multi Occurrence Data Structures cannot be dynamic
Arrays can be dynamic

What I have done is create a static MODS, I just call the routine over and
over.  (i.e. fetch 200 rows into 200 MODS, repeat if necessary)

What I thought was that you had figured a way to use the dynamic array to
replace the MODS method

The goal is to come up with the equivalent of 'result set'

Andrew,

It's still not working. It is not allocating the size of the pointer. I'll
post the code.

What's happening here is that the occur value is out of range. There are
still only 10 occurrences of the MODS even though there are 13 records in
the file.


Thanks,

Mark
