Thread: Any idea about using \COPY in ECPG statement

Any idea about using \COPY in ECPG statement

From

Hi All,

 

Does anybody have an idea about how to write \COPY command as an ECPG statement?

 

EXEC SQL \COPY tablename to ‘sample.csv’ DELIMITERS ‘,’ CSV HEADER

 

I want to perform the above psql command using an ECPG statement. No way of using COPY due to not availability of a super-user account. Could anyone guide me on this?

 

Thanks and Regards,

Siva.

Hello

its' not possible. But you don't need a superuser account for COPY
necessary. You can use a SECURITY DEFINER functions.

are you a broken record?  I've answered this several times now.

COPY .... TO STDOUT....

and capture the output with |PQgetCopyData|  or whatever the equivalent
is in your favorite language binding.
