Not able to insert binary Data having NULL
Hi,
I have bytea column in one table and using C language, I am trying to
insert a binary data (having NULLs)
into bytea column, but it just inserts/updates till NULL reached.
Please let know whether I am missing something.
Any other approach - may I use some data type instead of bytea so that
any binary data can go there?
Best Regards,
Manish Jain

Probably, but you'll need to explain how you're doing it at the moment.
How are you escaping your binary data?

I guess that when you say NULL you don't mean SQL NULL, but
the byte E'\\000', right? The rest of my E-Mail is based on
that assumption.
When calling PQexecParams to store a bytea, either set
paramFormats[i] to 0 (text) and use escape sequences as above,
or set paramFormats[i] to 1 (binary) and dont't forget to set
paramLengths[i] to the length of the binary data.

Large Objects.
But there's nothing wrong with bytea.
