Hi,
I tried to create an external proc but when I queried the user_objects , i did not find the object.
I am using personal oracle8,connected to Beq-local
database.
outstr is the name of the function in C.
Can anyone tell where is the error .
is any modification reqd to listener or tnsnames.ora
here is the method I followed :
create library fprntlib as
'f:extc_shared_libdll_prj.dll';
library gets created.
create or replace procedure filpr(ip_mesg varchar2,ip_fpath varchar2,ip_flg number)
as external
Library FPRNTLIB
NAME "outstr"
PARAMETERS(ip_mesg string,ip_fpath string,ip_flg int);
begin
filpr('First Line...','f:extfilpr.log',0);
filpr('Second Line...','f:extfilpr.log',1);
end;
error :identifier filpr must be declared.
