Hi Lefteris,

Thank you for your guide on MAPI document, but i still didnt find my need. 

what i want to do is if i define a function binarycopy() to copy bindary data into BATs in monetdb, how to call it in a C program?
because monetdb doesn't supply such function in built-in functions, this function is like postgresql's function PQputCopyData.

This function is  used to send data during COPY FROM STDIN.
int PQputCopyData(PGconn *conn,
const char *buffer,
int nbytes);
Transmits the COPY data in the specified buffer, of length nbytes, to the server.


I just want to build such a similiar function in monetdb now. 


Thank very much!

Meng

I think your best chance to find an answer to your question is here

http://www.monetdb.org/Documentation/Manuals/SQLreference/Programming/MAPI

please read the available documentation for MonetDB. I hope this shows
you the way to achieve your task.
