Re: Large XML file processing via XMLTABLE

It might be due to my own ignorance, but when I attempt to specify the
path name directly on mailingNumber and imbNumber I am getting an error
regarding duplicate elements.
So it seemed to me that I needed to set the XPath to the lowest unique
data element "IMB_Personalization/MailingData/Personalization".
Then, based on examples I found, to load data elements above the original
xpath I "needed" to use relative Xpath notation.

Are you suggesting I try somethig like:
mailingNumber varchar(5) default ' ' path '
IMB_Personalization/MailingNumber'
, imbNumber varchar(21) default ' ' path '
IMB_Personalization/MailingData/IMB_Number'
?

My understanding of the columns clause is that the columns paths are
described relative to the XMLTABLE XPath clause.

I will gladly take any suggestions on how to make this SQL statement more
efficient.

Hi Paul

is there any reason for the following statements uses relative Xpath
instead of named Xpath?

mailingNumber varchar(5) default ' ' path
'../../MailingNumber'
, imbNumber varchar(21) default ' ' path '../IMB_Number'

They may cause some processing overhead.

Just an idea

As a test of the new native Mono .Net environment on IBMi, I wrote a

little C# console app to shred a sample 29mg XML file and write to a CSV
file.

The program runs on my laptop in 3 seconds.

The same exact EXE copied to IBMi ran for about 45 seconds. (Pase Env)

Not bad for a native .Net app.
