Обсуждение: How to fill 'bytea' columns?!?

Hi!

After long scratching and searching, I've come to conclusion that I'd like to
use the 'bytea' type, because it should be able to hold binary data.

But, I've found no doc or FAQ or whatever on that type.

How does one use it? More specifically, how do I get binary values into a
'bytea'
column using SQL, and how do I get it out?!?

I hope someone can help me out.

TIA,
    Joe

Depends what exactly you want to do.

If you want to do it from a client-side perl program, just use DBD::Pg and
bind the values as SQL_BINARY.

If you want to do it from server-side, look at contrib/pgcrypto, and at
the encode/decode functions.

Thanks for your answer, but... it's neither Perl nor server side, it's
plain old libpg
for a programming environment named LabVIEW.

So, question stands. How to?

TIA,
