Обсуждение: postgres and xml

Hi All,

Is there a way that makes it possible to export sql query results as a xml file?
I use postgres 7.4.7 on a debian system. Do i need any packages to
export query results as a xml file if its possible?

Thank you
Hrishi

No, we have discussed it but it seems there is no standard XML export
format for databases, so you have to use something to use the COPY
output into XML.  Perhaps there is an CSV to XML conversion tool you can
use.

While there isn't a "format" for XML from databases, it is possible to
dump stuff from the database into some form of XML.  You could then use
XSLT to transform it into other forms as needed.

Here is a link of interest, but there are numerous others like it.
