Re: Dynamic SQL fetch into an array

Thanks for the reply Michael.

This causes the SQL pre-compile to fail with the error:

MSG ID SEV RECORD TEXT
SQL0312 30 787 Position 27 Variable SCHRECORD not defined or not usable.

I suspect it compares the number of fields in the DS versus the number in the fetch and barfs all over itself. Perhaps it thinks that the overlay is an additional field.

change

d arrRT 3 0 dim(7)

To

d strRT 21
d arrRT 3 0 OverLay(strRT) dim(7)


I haven't tested, but it's worth a try.

After beating my head against this issue, I've searched the archives and
the
Internet with no luck. I am attempting to fetch a record in embedded SQL
and this record includes a 7-element array. I'm fetching from a
program-described file (QS36F).

I've oversimplified the code below - I just need to get the basic concept.


d SchRecord ds
d c@ 1 5 0
d typi 6 6 0
d fschi 7 7 0
d cyci 8 8 0
d arrRT 3 0 dim(7)

sqlstmt = 'select +
substr(K00001,1,5) as c@, +
substr(K00001,6,1) as typi, +
substr(K00001,7,1) as fschi, +
substr(K00001,8,1) as cyci, +
substr(F00001,1,21) as arrRT +
from qs36f/"DS.SCH"

exec sql
prepare P1 from :sqlstmt;

exec sql
declare C1 cursor for P1;

exec sql
open C1;


dou sqlstt <> '00000';

exec sql
fetch C1 into :SchRecord;

if sqlstt <> '00000';
leave;
endif;

Etc.



The other fields read in properly but "arrRT" reads in as a single 3-digit
field instead of an array of seven 3-digit elements. I defined it as an
array in the DS - why does SQL ignore that?

I have to do this as dynamic because of the "where" and "order by" clauses
that are needed.

Any thoughts are appreciated. I'm starting to feel like Danny Noonan in
Caddyshack ("right in the lumber yard").
