I need to output the column names as a header row from a predefined view. How can I accomplish this?
I know that I could put all the column names into a SELECT ... FROM DUAL
UNION
SELECT * FROM VIEW
but this would not be dynamic and I would have to remember to change both statements whenever I add a new column to the view.
I also know that the ALL_TAB_COLUMNS has the name of each column in the view, but each column name is a seperate record and I need to string the output across in a single record.
Any help is appreciated.

Hi,
i do not know why u want to put the header into the view it self.because when u select the view it comes with the header.
next problem is that, u will not be able to union always because the header information is always varchar2 and your data in view may be of different kind.
cheers

We are executing the view from a PERL script which is then outputing the data to a DAT file for an external client to pickup via FTP. The client requires that there are column headers in the output.
