3.7. Functions Associated with the COPY Command

The COPY command in PostgreSQL has options to read from or write to the network connection used by libpq++. Therefore, functions are necessary to access this network connection directly so applications may take full advantage of this capability.

As an example:

PgDatabase data;
data.Exec("CREATE TABLE foo (a int4, b char(16), d double precision)");
data.Exec("COPY foo FROM STDIN");
data.PutLine("3\tHello World\t4.5\n");
data.PutLine("4\tGoodbye World\t7.11\n");
...
data.PutLine("\\.\n");
data.EndCopy();
