Обсуждение: how to use COPY within plperl

Hello,
I need to use COPY (instead of INSERT) within plperl function. I know
that COPY will work if data will be taken from file - however I need to
use STDIN. I tried this:
spi_exec_query("COPY sometable (field1, field2) FROM
stdin;"."\n"."sometext"."\t"."sometext"."\n"."\.")

But it didn't work. Thanks in advance.

Why can you not use simple insert statements (sql insert).
Copy is meant to transfer large amount of data from text files to
databases and vice versa.

"Insert" is much slower if there are many (hundreds, thousands) data to
be inserted - and in my case there will be thousands of inserts made by
plperl. I can make a file with the data (and load using COPY), but it
would be better to use copy from stdin.

Thanks
