From the docs i understood, that with COPY SQL command we should use
for synchr. sending:
PQexec
PQResultstatus returns PGRES_COPY_OUT
PQputCopyData
PQputCopyEnd
PQResultstatus returns PGRES_COMMAND_OK
How should look the structure of buffer in
int PQputCopyData(PGconn *conn,const char *buffer,int nbytes);
id for me clear (it should be the same like for example in text dumps of
tables done with pg_dump).
The question is:
Can I in function:
int PQputCopyData(PGconn *conn,const char *buffer,int nbytes);
use as a result buffer directly given by using PQexec for SELECT SQL
command ?
In other way:
Is the structure given as result of PQexec with SELECT SQL command
directly usable as buffer for PQputCopyData ?
