.TH PGEASY INTRO 08/08/98 PostgreSQL PostgreSQL
.SH DESCRIPTION
Pgeasy allows you to cleanly interface to the libpq library,
more like a 4gl SQL interface.
.PP
It consists of set of simplified C functions that encapsulate the
functionality of libpq.
The functions are:
.nf
PGresult *doquery(char *query);
PGconn *connectdb();
void disconnectdb();
int fetch(void *param,...);
int fetchwithnulls(void *param,...);
void reset_fetch();
void on_error_continue();
void on_error_stop();
PGresult *get_result();
void set_result(PGresult *newres);
void unset_result(PGresult *oldres);
.fi
.PP
Many functions return a structure or value, so you can do more work
with the result if required.
.PP
You basically connect to the database with
.BR connectdb ,
issue your query with
.BR doquery ,
fetch the results with
.BR fetch ,
and finish with
.BR disconnectdb .
.PP
For
.IR select
queries,
.BR fetch
allows you to pass pointers as parameters, and on return the variables
are filled with data from the binary cursor you opened. These binary
cursors can not be used if you are running the
.BR pgeasy
client on a system with a different architecture than the database
server. If you pass a NULL pointer parameter, the column is skipped.
.BR fetchwithnulls
allows you to retieve the
.IR null
status of the field by passing an
.IR int*
after each result pointer, which returns true or false if the field is null.
You can always use libpq functions on the PGresult pointer returned by
.BR doquery .
.BR reset_fetch
starts the fetch back at the beginning.
.PP
.BR get_result ,
.BR set_result ,
and
.BR unset_result
allow you to handle multiple result sets at the same time.
.PP
There are a variety of demonstration programs in the
.BR pgeasy
source directory.
