Обсуждение: SQL queries inside a C function?

Hi everyone,

How do I get the active connection handle from inside a C function linked as a PL/pgSQL function, like:

Datum pg_do_something(PG_FUNCTION_ARGS)
{
  PGconn *conn = ....?
  // now do some SELECTs / INSERTs
  PG_RETURN_INT32(result);
}

Thanks,
Elliot

Hello

you can use a SPI interface
