Hi,

I have problem with connecting to Navision Native DB thought ODBC.
I wrote simple program that connects to Navision DB thought ODBC, it works fine. Then - extended stored procedure for SQL server, but it throws exception then connecting DB

.........
dbconnect->OpenEx("Database=C:\\Navision Attain\\Client\\database.fdb;RD=No;DSN=NavisionDB;CSF=No;CN=CRONUS Lithuania u.a.b.;CC=Yes;OPT=Text;CD=No;ML=1063;SERVER=N;BE=Yes;IT=All Except DOT;PPath=C:\\Navision Attain\\Client;QTYesNo=Yes;RO=No",CDatabase::noOdbcDialog);
......

Exception: ex->m_strError == -1
ex->m_strError == „ISAM error“

What does it mean?
And more, if connect string is
“MaxBufferSize=2048;FIL=MS Access;DSN=UsersDB;PageTimeout=5;UID=admin;DBQ=D:\\WORK\\JAVA\\DATABASE\\Users.mdb;DriverId=25”
– Access DB then every thing works fine, xp too.

I don’t get it, what’s wrong?

fdb? was that a typo posting here, or is it a typo in your program? There are several programs that crete databases with the FDB extension, on the correct connect string you have .mdb, so I assume it's a typo.
If it's a typo here, then please try to paste the correct exact connection string. If it's a typo in the program, then that could be the cause.

.fdb it is Navision Attain Native Database. And connection string here is correct, because I can connect with it in my program, but then the same code in extended stored procedures – crashes. :((
Thanks any way!!!

Can you post the procedures here? The problem could be in the procedure itself, not in the connection string.
In fact, if you say you can do it with your program, then it must be in the procedures.
Anyway, can you post the code so we can try to find something wrong with it, please?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Ok, np =)
CODE:

#include <string.h>
#include <afxdb.h>
#include <atlstr.h>
#include <Srv.h>
#include <stdio.h>
#include "XP_GetNavisionTable.h"


SRVRETCODE  xp_getnavisiontable(SRV_PROC* srvproc);
ULONG __GetXpVersion();
void printMessage(SRV_PROC *pSrvProc, CHAR* message);


ULONG __GetXpVersion()
{
    return ODS_VERSION;
}

SRVRETCODE  xp_getnavisiontable(SRV_PROC* srvproc)
{
                DBCHAR colname[500];
   
      //_snprintf(colname, MAXCOLNAME, "Text");

      printMessage(srvproc, "1");

                                      ///...
                  /// printig
                  ///...
            }
            record->MoveNext( );
      }
      printMessage(srvproc, "6");

      delete record;
      delete dbconnect;
      printMessage(srvproc, "7");
//////////////////////////      

               //srv_sendrow(srvproc);

      srv_senddone(srvproc, SRV_DONE_MORE | SRV_DONE_COUNT, (DBUSMALLINT)0, 0);

      return  XP_NOERROR;
}

void printMessage(SRV_PROC *pSrvProc, CHAR* message)
{
    srv_sendmsg(pSrvProc, SRV_MSG_INFO , 0, SRV_INFO, 1,
                  NULL, 0, (DBUSMALLINT) __LINE__,
                    message,
                      SRV_NULLTERM);
}

This is my tiny stored procedure,
If you fide an error or soliution it would be greate!!! Because I looking for soliution all this week :((

Can you also insert the code for XP_GetNavisionTable.h? Since the procedure seems to be loading from definitions there, the error could be there, or, at least, it could help understand where the error might be coming from.

Ok, I will check on that and reply to you this weekend. With some luck, tonight. I'm at work now and having a busy day, so I can't really focus on that now, but I already printed it and will check it on my way home on the train! ;-)

Ok, I couldn't find an error, as your code is above my knowledge, but I passed your question to an "expert" I know! As soon as I have an answer, I'll let you know! ;-)
BTW, you're using VC++, right?

Yep, I using VC++ .NET
I asked some "experts" too, but still didn't get any answers or they couldn't help me.
