HI all,
I am trying to use oracle object types in pro*c/c++ program. Below are the detailes.
objects being used OBJ_BACKGROUND_JOB , OBJ_BACKGROUND_JOB_ARRAY.
ott infile : inpfile
CASE=SAME
TYPE OBJ_BACKGROUND_JOB
TYPE OBJ_BACKGROUND_JOB_ARRAY
ott command : ott userid=scott/tiger code=C intype=inpfile outtype=ottouttype hfile=obj_background_job_array.h
the command generated the header file and an outtype file
obj_background_job_array.h :
#ifndef OBJ_BACKGROUND_JOB_ARRAY_ORACLE
# define OBJ_BACKGROUND_JOB_ARRAY_ORACLE
#ifndef OCI_ORACLE
# include <oci.h>
#endif
typedef OCIRef OBJ_BACKGROUND_JOB_ref;
typedef OCITable OBJ_BACKGROUND_JOB_ARRAY;
struct OBJ_BACKGROUND_JOB
{
OCINumber SNO;
OCIString * PARAMETER;
};
typedef struct OBJ_BACKGROUND_JOB OBJ_BACKGROUND_JOB;
struct OBJ_BACKGROUND_JOB_ind
{
OCIInd _atomic;
OCIInd SNO;
OCIInd PARAMETER;
};
typedef struct OBJ_BACKGROUND_JOB_ind OBJ_BACKGROUND_JOB_ind;
ott outtype file : ottouttype.typ
CASE = SAME
TYPE OBJ_BACKGROUND_JOB AS OBJ_BACKGROUND_JOB
VERSION = "$8.0"
HFILE = obj_background_job_array.h
TYPE OBJ_BACKGROUND_JOB_ARRAY AS OBJ_BACKGROUND_JOB_ARRAY
VERSION = "$8.0"
HFILE = obj_background_job_array.h
below is the proc code in which I am using the above defined types : types.pc
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sqllib.h>
#include <sql2oci.h>
#include <sqlda.h>
#include "obj_background_job_array.h"
#define SQLCA_STORAGE_CLASS extern
int main()
{
EXEC SQL BEGIN DECLARE SECTION ;
OCIString * abcd ;
OBJ_BACKGROUND_JOB * obj_background_job ;
OBJ_BACKGROUND_JOB_ind * obj_background_job_ind ;
OCIString * abc ;
EXEC SQL END DECLARE SECTION ;
EXEC SQL ALLOCATE :abc;
EXEC SQL ALLOCATE :abcd;
EXEC SQL ALLOCATE :obj_background_job:obj_background_job_ind ;
.
.
.
return 0 ;
}
When i compile the above code using the command :
proc types config=pcscfg.cfg
i get the below error
Syntax error at line 24, column 9, file types.pc:
Error at line 24, column 9 in file types.pc

PCC-F-02102, Fatal error while doing C preprocessing
contents of pcscfg.cfg is :
USERID=scott/tiger
code=cpp
parse=none
define=DM_PAGE_SIZE
release_cursor=yes
sqlcheck=semantics
INTYPE=ottouttype.typ
OBJECTS=YES
sys_include=(/apps/util/oracle/product/11.1.0-64bit/precomp/public,/opt/SUNWspro6u1/WS6U1/include/CC4,/usr/include)
ltype=short
MODE=ORACLE
It seems INTYPE=ottouttype.typ parameter doesnt have any effect on the proc command.
Please suggest on how to resolve the problem ... Thanks in advance for your help.

you have some syntax error. I am no expert in C but I can offer these observations from plsql when I get the same error. In order of most common mistakes:
1) missing a quote
2) missing a matching end for some start.
Example IF with no matching end if; loop with no matching end loop;
The problem is usually that the end tag exists but is out of place.
3) missing an ending token (eg. ; in plsql)
4) missing some other token (exp. said = instead of :=)
5) mis-spelled some variable and the parser is confused so it reports an erroneous error.
I suggest you look for a syntax error of the types above, the C version of course.
My approach to solving the problem is to comment out everything, and then compile iteratively bringing in small pieces as I go. Eventually I find the line/section with the error and then it is easier to see and fix.
Good luck, Kevin

Hey Kevin,
I also did the same procedure of commenting/uncommenting the code , the code gets compiled if i comment the code instantiating the ott structures as host variables. I can use them as a normal C structures and operate on them, then here i cannot use the sql command like allocate, object get , object set on those C variables.
