Re: Working with XML. - Mailing list pgsql-sql

Hi Theo,

 

Hmm.  Well we're getting into territory that's over my head.  I've simply been a user of xml2 and do not know much about its inner workings.  Just out of curiosity, what is the size of Sort_Mem in your postgresql.conf?

 

Regards,

George

George,

 

    I have run this SP in Cold Fusion, PgAdmin and EMS PostgreSQL Manager 2, with all the same results. We are currently using Redhat ES3 and Postgres 7.4.5.

Hi Theo,

 

I am not able to duplicate the problem you experienced.  I tried the query you provided below using pgAdmin and psql on a 7.3.2 and an 8.0 database with success.  I then copied all the rows and pasted them to the end so that I would have 100 rows, and the query worked as expected.

 

Perhaps the client you're using is causing the problem.  Can you run the query in pgAdmin?

 

Regards,

George

Thankyou George,

 

XML2 compiled ok... next stummbling block..  when I pass a very long XML string to xpath_string() it crashes the postgres server. Client receives a message like:

 

server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.

 

Below is the function call, a smaller xml string with say 40 records works fine, anything bigger crashes the server.

 

select xpath_string('<?xml version="1.0" encoding="UTF-8"?> <query columns="4" rows="50"><row><cola>774187</cola><colb>222663</colb><colc>2005-02-22 <snip>
