Checking for errors is good:
# include <stdio.h>
# include <stdlib.h>
# include <libpq-fe.h>
int main()
{
PGresult *result = NULL;
PGconn *conn = NULL;
int feild;
printf("successful");
conn = PQconnectdb ("ashok");
if (!conn || CONNECTION_BAD == PQstatus(conn)) {
fprintf(stderr, "Connection to database failed.\n");
fprintf(stderr, "%s", PQerrorMessage(conn));
exit(EXIT_FAILURE);
}
result = PQexec (conn, "select * from bill");
if (!result || PGRES_TUPLES_OK != PQresultStatus(result)) {
fprintf(stderr, "select command returned no tuples\n");
fprintf(stderr, "%s", PQerrorMessage(conn));
exit(EXIT_FAILURE);
}
feild = PQntuples (result);
printf("%d",feild);
PQclear (result);
PQfinish (conn);
printf("hello");
return EXIT_SUCCESS;
}
