Обсуждение: Preparing statement using PQexec vs PQprepare

Hello,

Is preparing a statement using PQexec and executing it is much slower that
using other API such as PQprepare and PQexecPrepared?

Best regards,
Mark

PQexec can be faster than a combination of PQprepare and
PQexecPrepared particularly if you only need to execute the query
once, but I don't recommend using it for the most part.   If the query
is to be executed many times, or has a lot of parameters, you'll want
to use the prepared interface.
