hi there!

i wanted to ask how to get an xml output from a table like this:


joe
ian
carl
 ben


what i have is the following:


SELECT xmlelement(name words,


xmlforest(nachname))
FROM person
SELECT
xmlelement(name words,
xmlforest(nachname))
FROM person

but that gives me this:

joe
ian
 carl
ben


thanks in advance!

bye, flo






You need to use xmlagg:

SELECT
xmlelement(name words,
    xmlagg(
        xmlforest(first_name)
    )
)
FROM person

Hi!

Thanks, that worked perfectly for me, except for one problem. 

I have like 20 times the name "Joe" in my table, but want to get it only once in the xml output file. 

How can is do this? I tried SELECT DISTINCT but it didn't work.

Thanks in advance!
