Hi All.
I am using PQputCopyData function to send data to server one row at a time. When I am done with the data then I call PQputCopyEnd.
I want to do rollback when any error occurs. Please help me how to achieve rollback using these functions.
Thanks,
Sandeep Khandelwal

As the documentation for PQputCopyEnd() says, you can pass a non-NULL
second argument to force the copy to fail. You could also use PQexec()
to execute a BEGIN before the copy and a COMMIT or ROLLBACK after the
copy.
