Hi Lim,

The DDS manual says Hex fields are treated as character except that they
are not translated, i.e. something like having a ccsid of 65535 on a
character field.

It's probably trying to convert because you're comparing it to
non-character fields, e.g. :reqHExt.UHFrmDtInEpoch. What are these
fields defined as? Can you use DIGITS or CHAR on them to convert them
to character?

I've a file with a lot of fields declared as Hex type. These hex
fields seems to causing my SQLRPGLE program to error out with SQL0802.

This appears to be cause by sql is trying to convert those Hex fields
into integer. Is there a way to prevent this conversion from taking

place?

Below is what the error looks like:
Cursor ECDHDRCURSOR opened.
Select or omit error on field (Cast(ECDHDR_1.XMITEPOCH[1], Char
Pad(x40,x4040)) AS 4-byte int) member HR0108.
Select/omit error on member HR0108.
Select/omit error on member HR0108.
Data conversion or data mapping error.



Below is portion of the file DDS looks like
A R RECDHDR
A SUB 4H
A XMITEPOCH 4H
A TCAPCODE 4H
A RECNO 9B 0
A LW5 4H




Below is what how I declared the sql cursor:
declare ECDHDRCursor cursor for
select * from ECDHDR a
where
a.XMITEPOCH >= :reqHExt.UHFrmDtInEpoch and

a.XMITEPOCH >= :reqHExt.UHToDtInEpoch and

exists
(select 1 from qtemp/customerList b
where
b.LW10 = a.LW10
) and

exists
(select 1 from qtemp/tidSubList c
where
c.tid = a.tid
)



Below is what the fetch looks like
fetch from ECDHDRCursor into :CDRH
