I’m using PG v12.6 and no I haven’t tried the path function. Do you have an example?

Hi All,

 

I am attempting to port the following statement from DB2z to Postgres:

 

SELECT e.empno, e.firstnme, e.lastname,

          XMLELEMENT ( NAME "foo:Emp",

            XMLNAMESPACES('http://www.foo.com' AS "foo"),

            XMLATTRIBUTES(e.empno as "serial"),

                          e.firstnme,

                          e.lastname ) AS "Result"

       FROM EMP e

       WHERE e.edlevel = 12;

 

The NAMESPACES function is not supported by Postgres in the XMLELEMENT function. Is there any way to get this to work? I’ve looked at the WITH syntax but it doesn’t look like that will be helpful here.

 

 

Which Postgres version?  Have you tried path function?

Garfield
