No problem Steve, thanks for the info mucho gracias


I didn't see this entry because of the way my email gets sorted. Sorry!

Using SQLtype(), you can define variables that go beyond the 64K char
limitation within RPG.

Found the chart below at

Subject: RE: using a DS with a stored procedure xml method

The only problem I see here is that a char has a limit of 65,535 so I'm a
little lost on how you can pass 2 gb of data in an xml doc....


You can format the entire pile of data as xml and pass it as an input
parameter field that is described as a CHAR that is as big as you
need, or as a BLOB or CLOB as needed (you will need to use SQL to
define these data-types)).



Define the xml's structure with repeating structures to represent the
multiple rows.



<xml>

<row>

<field1 />

<field2 />

<field3>some data</field3>

</row>

<row>

<field1 />

<field2 />

<field3>some more data</field3>

</row>

</xml>



Then describe in your RPG program a DS that describes each row as an
occurrence for as many as is reasonable (if this varies or can be
greater than the DS can handle, you can use %handler to parse portions
of the XML at a time).



DPlist PR Extpgm('program')

D Parm_XML 31000

*

DPlist PI

D Parm_XML 31000



D XML_in ds Qualified

D row likeDS(rowDS) dim(2500)

.

.

.

D rowDs ds qualified based(only_a_template)

D field1 10

D field2 3 0

D field3 17

.

.



Then use the XML-INTO verb to parse the data from the XML input
parameter into the DS you defined.



XML-INTO(E) xml_in %xml(Parm_xml:'allowmissing=yes allowextra=yes
case=any');



Then just process the row ds as you normally would any other qualified
ds.



Performance is surprisingly good in our interactive web
environment...your results may vary, blah, blah, blah...:-)



Good luck!



BTW - this info is all in IBM's RPG manuals too.

Subject: using a DS with a stored procedure



I'm looking at using a stored procedure (which references an existing
RPGLE program) for connecting to an external process. I would need to
be able to send multiple rows.



We have a windows app that would call a stored procedure and pass it
approximately 59 fields of data, but it can contain up to 99 rows of
data.



Is this even possible? I was thinking of just defining the full length
of the data structure and using that as a clob field or something
along that lines but it doesn't sound very efficient.



Websphere and a web service is not an option, the owner flat out shot
down spending the money for that. So I'm back to square one.
