Hi postgressers,
My function given below doesn't work.
/* method_folder.c - to retrieve tuples with fldrname = "DEFAULT" */
#include "/home/coyote/postgres/src/backend/tmp/libpq.h"
#include <utils/builtins.h>
#include <tmp/libpq-fe.h>
bool method_folder(t)
TUPLE t;
{
char folder_name[100];
strcpy(folder_name, (char *) GetAttributeByName(t,"fldrname"));
printf ("FOLDER NAME %s\n",folder_name);
if (!(strcmp(folder_name,"DEFAULT")))
return (1);
else
return (0);
}
I used the following command to define the function :
define function method_folder (language = "c", returntype = bool) arg is
(FOLDERS) as "/home/coyote/postgres/final/method_folder.o" \g
I ran the function with the command :
retrieve (FOLDERS.all) where method_folder(FOLDERS) \g
The error message I get is :
Welcome to the C POSTGRES terminal monitor
Go
*
Query sent to backend is "retrieve (FOLDERS.all) where method_folder(FOLDERS) "
WARN:Nov 26 20:44:22:GetAttributeByName: a NULL isNull flag was passed
sed
Go
Any suggestions would be appreciated.
Thanks,
Sriram Kal.

response -I badly need help.
My function given below doesn't work.

#include "/home/coyote/postgres/src/backend/tmp/libpq.h"
#include <utils/builtins.h>
#include <tmp/libpq-fe.h>
bool method_folder(t)
TUPLE t;
{
char *folder_name;
folder_name = (char *) malloc (100);
strcpy(folder_name, (char *) GetAttributeByName(t,"fldrname"));
printf ("FOLDER NAME %s\n",folder_name);
if (!(strcmp(folder_name,"DEFAULT")))
return (1);
else
return (0);

GetAttributeByName takes three arguments. the third argument is a
Boolean by-reference argument that indicates whether the attribute is
NULL.
this was documented incorrectly in 4.1 but the documentation was
finally fixed in the last release..
