Oracle ODBC Driver and Numbers in ASP

When I try to retrieve a number field from my RecordSet I allways get 0, allthow when viewing the field from SQL Plus I get another value.
objRs is an ADODB.resultSet and state is a Number(5) field.
I've tried:
objRs("state")
objRs("state").value
objRs.Fields("state")
objRs.Fields("state").value
but they all return 0
null

1) As I recall, the problem of returning 0 is caused either by an outdated version of the ODBC driver or of the MDAC (Microsoft Data Access Components). Updated versions of the ODBC driver are available here on OTN and updated versions of the MDAC are available at <http://www.microsoft.com/data>.
2) Versioning-
To determine the version of the Oracle8 ODBC driver you should be using, simply match up the first three digits of the ODBC driver version and the Oracle client version (see chart Mr. Oehl posted). The 8.1.5.6 ODBC driver should go on an 8.1.5.x.x system, the 8.1.6.1 ODBC driver should go on an 8.1.6.x.x system. If you have an Oracle7 client, you'll need one of the version 2.5x Oracle7 ODBC drivers.
Any ODBC driver should connect with any Oracle database. No need to match anything up there. You can determine the version of the database you're connected to by calling the ODBC function SQLGetInfo with the InfoType SQL_DBMS_VER.
A little elaboration on version numbers
- Oracle versions are generally 5 digits (i.e. 8.0.5.2.4, 8.1.5.1.1). The versions that you get on CD's are generally (always?) x.x.x.0.0 versions (i.e. 8.1.5.0.0, 8.1.6.0.0). The last two digits are incremented by periodic patchkit releases <ftp://oracle-ftp.oracle.com/server/patchsets/wgt_tech/server/windowsNT/>
- ODBC drivers must report versions in 4 parts, each part having 2 digits (i.e. 8.01.05.05). Since we're lazy about typing extra 0's, we simplify this and just refer to the 8.1.5.5 ODBC driver.
- The 8.1.5.x ODBC driver is built with the client libraries that ship with Oracle 8.1.5.x.x, the 8.1.6.x ODBC driver is built with the client libraries that ship with Oracle 8.1.6.x.x, etc. This is why I said above that you need to match the first 3 version numbers between Oracle client and ODBC driver to determine which to use.
I hope this is more enlightening than confusing...

Setting up an Oracle ODBC Driver and Essbase

Hi all,
I am trying to retrieve data directly from Essbase into SAS (Statistical Analysis Software) by setting up an Oracle ODBC Driver and Essbase.
I read this document in the below link and I was convinced that I could use ODBC to connect to Essbase, but our data administrator says that Essbase is an OLAP database and can NOT use ODBC.
http://docs.oracle.com/cd/E10530_01/doc/epm.931/esb_sqlint.pdf
I am a SAS programmer, but I have no background in technical configuration, so I was wondering if someone can help me if it is really possible or not to connect to Essbase using ODBC.
If it is possible, I have a follow up question...
I followed this link below to do a set up and did so successfully before the actual step to add a new data source to ODBC driver.
I should be able to select the TNS Service Name from the drop down list. This name will be that which I named in the TNSNAMES.ora file’s Alias = section, but I don’t see this option…
It would be great if someone knows why I do not see this option populated under drop-down in the screenshot.

Oracle ODBC driver and TIMESTAMP with timezone

Does anyone know if it is possible to return data from a "TIMESTAMP WITH TIMEZONE" column using the Oracle ODBC driver and an ADO Recordset?
I am using the Oracle driver version 10.2.0.2 and TIMESTAMP fields work fine.
I can call Recordset->Open() with a query like "SELECT * FROM TABLE" when the table contains a column of type timestamp with timezone but when I execute a statement to see if there are results as in
if (!(srcRecsetPtr->BOF && srcRecsetPtr->EndOfFile))
my application throws an unhandled exception and exits. The exception is not a COM exception and I'm not sure how to get back additional information if that's possible.
The only information I've been able to find in searching TechNet and MetaLink is that a workaround is to wrap the columns in a TO_CHAR or TO_DATE conversion first but that's not a good solution for my problem since I am executing user specified SQL which may join multiple tables.
I've found one other note that says the documentation should be corrected and that these fields are NOT supported period (Bug #4011640).
I've experimented with the Bind Timestamp as Date option in the ODBC connection and with various ALTER SESSION settings to attempt to change the NLS_TIMESTAMP_TZ_FORMAT but I have been unable to get past the problem.
Any ideas are greatly appreciated.
Thanks,
Troy

Hi Justin
Thanks for your help.
I tried what you mentioned and I could connect myself via SQL*Plus without passing a password and a login, Extern authentification seems to work and my user seems to be right configurated.
But he problem goes on via ODBC. When I test connection in the ODBC Data Source Administrator of Windows XP, test fails and seems to forbid connection without userID and password. When I try to connect via ODBC in my program the same problem appears : "Unable to connect SQLSTATE=28000 [Oracle][ODBC][ORA]Ora-01017: Invalid username/password;logon denied" I could not connect in this way.. What's wrong ?

Download and installing oracle odbc driver alone

Hi all,
I wanted to find out if I can download just the oracle odbc driver and install in without actually installing oracle database or client version on windows PC.
thank you

You will need to have some Oracle software on your machine for the Oracle ODBC driver to function.
If you can use the 10g client, you can install the 10g Instant Client and the ODBC driver. The Instant Client is a minimal set of libraries that allow components like the Oracle ODBC driver to work. The 10g client, though, is not certified to connect to databases earlier than 8.1.7.
If you have to use an earlier version, you have to install the full Oracle client, which is not a small install, to be able to use the Oracle ODBC driver.

Slow performance in W2K using Oracle ODBC Driver

My company is upgrading our NT4 servers to W2K. One or our App servers is running MTS with several packages, one of those being a dataaccess package that is responsible for all data actions.
In testing the OS upgrade, I found considerable performance degradation with our data access package. I finally solved the problem by changing the ODBC driver from Oracle ODBC Driver to the Microsoft ODBC for Oracle Driver. I have also found that under XP, I can still retain the use of the Oracle ODBC Driver without any performance hits.
All systems currently have the 8.1.7 Oracle Client and MDAC 2.7. I have also tried the Oracle Objects for OLE with similar performance losses in W2K.
More info about the problem...
In using the Oracle ODBC Driver, I connect this way -
Dim RS As ADOR.Recordset
Set RS = CreateObject("ADOR.Recordset")
RS.ActiveConnection = "DSN=" & p_strDSN & ";" & "uid=" & strUser & ";pwd=" & strPassword & ";"
RS.Source = "Select stuff from aTable"
RS.LockType = adLockReadOnly
RS.Open
Using W2K, I found that the majority of processing time comes from the RS.ActiveConnection call, not from object creation.
I would like to use an Oracle developed driver to connect to my database, however, I am forced to use the Microsoft driver. I have not seen any similar problem on this message board, nor have I seen any mention of this in MSDN's discussion board. Can anyone shed some light on what is going on?
Thanks,
Matt

The performance lag we have been seeing is in the milliseconds, but when we make repeated calls, those milliseconds add up. I am seeing a difference of about 7 - 10 milliseconds each call between the Oracle ODBC Driver and the Microsoft driver.
TNSPings seem quick in all setups as does the connection tests.
The Oracle ODBC driver version is 8.01.07.00. I haven't tried the new 8.01.07.6+ drivers yet. I'll give them a shot and reply back with results in a day or so.

ASP pages and Oracle ODBC Driver

I have a number of ASP pages that need to be updated to connect to Oracle using the ORACLE ODBC driver. Currently, these pages connect using the Microsoft ODBC driver for Oracle. I do not know of all the details yet as I havent seen the pages or network for which they reside on and I havent been supplied with details on version information. I would assume I am working with recent versions of all software.
What Im curious about is if anyone has done this sort of driver change before and if you have any suggestions on how I would go about doing this, or if there are things that I need to be aware of that arent evident at first glance.
Again, I am switching from the odbc driver provided by Microsoft to a version of the odbc driver provided by Oracle.
Thanks for any and all information.

I'll assume that there is some reason that necessitates switching drivers. If there's not going to be a benefit, I'd suggest not changing.
That said, changing drivers should be relatively painless. If your ASP makes database connections using DSN's, simply go to the ODBC Data Source Administrator, rename the old Microsoft DSN, and create a new DSN using the Oracle driver with the name your ASP is looking for. If your ASP specifies the ODBC driver in its connect string, you'll have to modify all the ASP connect strings to use the Oracle driver. If all goes well, your ASP will now be up & running using the Oracle driver.
As we all know, however, reality and theory are often at odds with each other. While your ASP should be connecting to the database correctly when you make these changes, please do some thorough testing to verify that everything works like you expect. The ODBC specification permits drivers to have a variety of behaviors in certain conditions. Applications written with one ODBC driver often end up relying on one of these behaviors, and may break when the ODBC driver changes.

Help w/ODBC driver and Oracle 7 (and maybe 8)

Hi,
Can anyone give me some information about using the Oracle ODBC driver for Windows? I know that it is no longer supported, but our application uses the Oracle 7 (7.3.4) client to connect to an Oracle 8i server. I have some reports written in a MS Access front end that connect through the ODBC (Oracle 7 driver) to the server.
When I run a query that takes a long time to return results, I find the connection times out whenever I use Windows2000/NT but is fine when I use 98. I also have this problem when I use the Oracle 8 client/driver and I am sure to remove the check from the "Enable Query Timeout" box in the ODBC setup. Again, even with 8, no problem on 98, but timeouts still happen on NT/2000
Is there a known bug out there on this and is there some way to fix it?
Thanks for your help and regards,
Eugene

The Oracle ODBC driver is certainly still a supported product. There are old versions (i.e. the Oracle7 driver that are no longer supported).
Which version of the Oracle 8 client & ODBC driver are you using? If you're using a older 8.0.x client and ODBC driver, those may not have been certified on Windows 2000. Can you connect to the database with SQL*Plus on the machines where the Oracle 8 client & ODBC driver are installed?
Is it possible that the user that's running the Access front-end doesn't have sufficient privs to the %ORACLE_HOME% directory? I know NT & 2000 actually enforce this sort of thing, where 98 doesn't.

How to install Oracle ODBC driver...?

TOM,
Presently, I have oracle client version. But there no Oracle ODBC driver in my PC. But, I want to install only Oracle ODBC driver in my PC for ODBC Connectivity purpose.
How to install & where can get the source?

I found out the real answer!!!
On another thread there was a link to the client 10g installation. I download that 480Meg monster. Unzipped the package and launced the setup.exe.
You can then install just the ODBC using the custom option. But, it will not install the tnsnames.ora file. If you have ever done this from a VB app, copy the tsnnames.ora over to the \network\admin folder. It's usually under the oracle\product\client\10.0.2\ folder. Once installed you can launch the ODBC administer either from the link Oracle installs or from the control panel.
Next, you need to make sure the folders where the .dll file is readable to the iis. Change the folder to add whatever permission group you use for iis (I happen to have setup a local users group {machinename\users}. Add them to the entire folder structure (check the embedded folders to ensure they are readable).
While setting up the ODBC, the TSN names will now be listed from the tsnnames.ora file (if properly located). To make the connection work, the userid should be 'userid;pwd=password'. Otherwise the connection failed for me.
Now, if your connection works okay from the odbc test connection, it will probably fail if accessing through iis (like from a .asp page). There are environment path variables that need to be set. Reboot the server for them to get set. Otherwise you will get a ODBC driver can not be loaded do to system error 1114 message.

MS ODBC or Oracle ODBC driver?

Can anyone tell me which is the correct driver to use when developing front end MS Access 2003 to retrieve and update data on a Open VMS platform with Oracle 8.1.7.3 database?
I have serval Access 2000 databases that run on most WinNT or W2K clients with a couple of W2K Dell exceptions. These Access 2000 db's connect to the Oracle database using linked tables and SQL pass-through queries that work with ODBC Manager-DNS system setup using the Microsoft for Oracle ODBC driver.
Now we are upgrading to Office Pro 2003 so new W2K images have been setup with Oracle 8.1.7 Client. SQL*Plus works on these clients but when I create the System DNS the Access databases return an error "ODBC connection failed". I can however connect with a pass-through query using Oracle's ODBC driver. Not enough time in roll-out plan to change the ODBC connection string in hundreds of Access SPT queries.
Please help!

Hi,
Since 9.2 has been desupported for error correction you will not be able to download that version from OTN. You should ask whoever is providing the training if their is an alternate version you can use. The only versions that you will be able to download from oracle.com is 10.2 11.1, and 11.2.

How to select active Oracle ODBC Driver programmatically?

Hi,
My application creates ODBC DSN to connect with Oracle 10g database server. I need to find out Oracle Driver installed on the system programmatically. I am trying to read KEY_<PRODUCT NUMBER> registry key and eventually searching ORACLE_HOME value. This helps me in searching Oracle Driver in ODBCINST.INI registry key. (Oracle in OraDb10g_home1)
If multiple Oracle clients are installed on the same system, multiple KEY_<PRODUCT NUMBER> registry keys and oracle drivers would be available. I am not sure which and how to select the current active oracle driver.
Oracle in OraDb10g_home1
Oracle in OraDb10g_home2
Can anybody help me out? Can I use inventory file (inventory.xml) to determince current active home directory? Reading PATH environment variable to identity active home directory would be tedious.

Please look at following thread for answer.

Hi:
I have installed the Oracle ODBC Driver version 8.1.7.8b on a WINNT 4.0 Workstation with SP6a. I have an MFC test app with the following code:
PostStatus(ERROR_NOERROR, APP_NAME, "Calling OpenEx()");
CDatabase db;
if(db.OpenEx(_T("DSN=MYTESTDSN;UID=USERID;PWD=PASSWORD"), CDatabase::openReadOnly|CDatabase::noOdbcDialog))
     PostStatus(ERROR_NOERROR, APP_NAME, "OpenEx() success,calling Close()");
     db.Close();
} // OpenEx()
else // OpenEx() error
     PostStatus(ERROR_MODERATE, APP_NAME, "Error opening database,OpenEx() failed!");
The above OpenEx call is taking upto 3 seconds to return. When I use Microsoft Oracle ODBC driver, it takes less than 0.5 sec to connect/disconnect.
Any idea why OpenEx() is taking that long? I've compiled this using VC++ 6.0 SP5, on a WIN2K and WINNT system but I get the same result.
Thanks,
Amit.

Installing Oracle ODBC driver from within another installation

My application requires ODBC driver. Is it possible/recommended
to install the driver from within my installation program (other
than invokig the ODBC's setup program)? If so, what are the
files that need to be installed, the registry entries that need
to be updated and other activities perfromed?
Thanks
Michael

In order for the ODBC driver to function properly, the Oracle
client must have been installed on the user's machine. If the
Oracle client has been successfully installed, users will have
the Oracle ODBC driver.
Since the Oracle client install is very large as installers
go, you probably don't want to package this with your app. In
addition, the Oracle client installation is pretty significant
in terms of what it does, so you definitely don't want to try to
replicate that work in your installer.

Oracle ODBC Driver 10.02.00.04 sqora32.dll with /*+ RULE */ base hints

Hi Everybody,
I have a problem with SQL queries with /*+ RULE */ base hints being posted to an Oracle database. I have reason to believe that these queries are generated by the Oracle ODBC Driver itself. Although I don't have a performance problem per se, I need to reduce these hints to a minimum so we can fine-tune the database as a whole.
* The views that are hit are always the same: All_Objects, All_Arguments, All_Synonyms,
* We are using Oracle ODBC driver 10.02.00.04 for Windows, the database server is a RS6000 with AIX and Oracle 10g,
* Aside Oracle Development tools, there are no applications, reports or similar gadgets that query the tables described above.
I would really appreciate any help about this issue.
Here is an example of the type of queries that I'm writing about:
SELECT /*+ RULE */ '', b.owner, decode (b.object_type, 'PACKAGE', CONCAT( CONCAT (b.object_name, '.'), a.object_name), b.object_name), NULL, NULL, NULL, NULL, decode (b.object_type, 'PACKAGE', decode(a.position, 0, 2, 1, 1, 0), decode(b.object_type, 'PROCEDURE', 1, 'FUNCTION', 2, 0))
FROM ALL_ARGUMENTS a, ALL_OBJECTS b
WHERE ( b.object_type = 'PROCEDURE' OR b.object_type = 'FUNCTION' ) AND b.object_id = a.object_id AND (a.sequence=1 OR a.sequence=0) AND b.OBJECT_NAME = 'MYTABLE' AND b.OWNER = 'MYSCHEMA' UNION
SELECT /*+ RULE */ '', b.owner,b.object_name,NULL, NULL, NULL, NULL,decode(b.object_type, 'PROCEDURE', 1, 'FUNCTION', 2, 0)
FROM ALL_OBJECTS b
WHERE (b.object_type = 'PROCEDURE' OR b.object_type = 'FUNCTION') AND b.OBJECT_NAME = 'MYTABLE' AND b.OWNER = 'MYSCHEMA' UNION
SELECT /*+ RULE */ distinct '', a.owner,CONCAT(CONCAT (a.package_name, '.'), a.object_name),NULL, NULL, NULL, NULL,decode(a.position, 0, 2, 1, 1, 0)
FROM ALL_ARGUMENTS a
WHERE (a.sequence=1 OR a.sequence=0) AND a.OBJECT_NAME = 'MYTABLE' AND a.OWNER = 'MYSCHEMA' ORDER BY 2,3

Hi Greg,
Thank you for your answer. One of the things that we did when we migrated to Oracle 10g was to ensure that the "Disable Rule Base Hints" flag, located in the "Work-arounds" tab in the ODBC DSN window is checked. We previously refreshed all Microsoft's Access databases to use this new DSN connection. Still, the hints are there.
However... we may have been able to link these calls to these Oracle System Catalog views, with a custom application that launces Crystal Reports.
Although we all know that Crystal Reports also caches ODBC DSN configuration settings, I must say that these same Crystal Reports do not generate hints when called from their InfoView server.
We will proceed to modify the custom application, overridding the dissable rule-base hint work-around with the string "DRH=T" on the connection string. Next week we will know if this works.
Best Regards,
Manuel
