I don't think that works  I think you have to use SQL commands since,
well, the function is running in the db, not in your client.

Look up the SQL COPY command instead.

Hi Chris,

I don't have super-user. So I knew I can go with only \COPY command. I want to export the data from a table to a .CSV
file.It worked fine when this command is used as a stand-alone. Now, I want to embed this line inside a function. Is
thereany alternative way for my requirement? Please guide me. John has proposed to see COPY to STDOUT which I am not
awareof, and started looking into it. However, the operations I said above have suppose to be done only on the database
side!

Thanks and Regards,
Siva.
