Hey all,
The description of PQprepare() of libpq
(
http://www.postgresql.org/docs/9.0/static/libpq-exec.html)
says:
(But
PQprepare is more flexible since it does not require parameter
types to be pre-specified.)
But the description of PREPARE
(
http://www.postgresql.org/docs/9.0/static/sql-prepare.html)
says:
The data type of a parameter to the prepared statement. If the data
type of a particular parameter is unspecified or is specified as
unknown,
it will be inferred from the context in which the parameter is used.
So, PQprepare() is NOT more flexible in this case because PREPARE
does not require parameters types to be pre-specifies also.
Regards,
Dmitriy
