thanks for Xquery info, I do not start to implenment the xmlquery() itself , maybe call xqilla lib or sth else in the future. I think xmltable is almost equal to xmlquery , except that it retuns talbeset insead of xml.
I take xmlconcat as an example , add xmlquery whereever xmlconcat appers and nothing else. the first problem is , I have to make xmlquery accepted by the parser. 2009/12/31 Andrew Dunstan <[email protected]> > > > fangfang liu wrote: > >> you mean create and replace funtion xmlquery()? >> maybe you are right, but I still want to know why parser does not find >> xmlquery. >> >> >> > We would have to see your code to know why it didn't do what you expect. > > What exactly are you intending that this function would do anyway?
