Re: SQLRPGLE Fetch with Null field values

It's in good practice (IMHO) to always use IFNULL, when the possibility of
null values can appear.
That way you your query won't bomb, and you can have a fall-back value if
it is null.

SQLRPGLE Fetch with Null field values






Hi all, I need help!
I'm trying to run a SQLRPGLE program with a Fetch Into clause with
possible null values.

The Select statement (skinnied down) is as follows:
Sel = 'Select oh, +
a.WHSE, a.SKU, a.HANDLCDE, a.COORDGRP, a.OH#MMS, +
From @SISYNWRK a left join @synppoh1d on a.sku = icmpno +
Where ( a.Flg_01 = '' '' and a.flg_08 = '' '') +

and a.Whse = ? and a.sku not in (select isetno from sethdr) ';


The Fetch is
Fetch Next from SelectStmt into :DSSis800

The host variable DSSis800 is defined as
d DSSis800 e ds extname(@SIS800WPF)

and the field OH is defined in DDS as 6S 0 with ALWNULL and DFT(0)

When I run the program I get a message "Indicator variable required."
and no data is copied.

How can I get this to populate the external data structure (I run the
Fetch through a Do Loop and write to the file), or how do I define an
"Indicator variable" for the null-capable field?

Thanks,
