Thread: parse bind execute

I'm writing C programs to access a PostegreSQL database usng the libppq
interface.  I am new to Postgres, so please excuse me if my question is too
basic.

I want to preparate (parse) and SQL insert statement and then in a loop,
bind the input variables and execute.  Is this possible using libpq or any
other Posgres interface from C?


Thanks in advance....

It is possible via ecpg the embedded SQL preprocessor for C. But be aware
that the PREPARE statement is only simulated since the backend does not
support it. That means you can do what you saif, but in fact everytime you
issue your INSERT it is parsed by the backend yet again.
