OraOLEDB, ADO and CursorLocation in VB6

Hi, I'm returning to the Oracle World after 8 years, I'm taking control of a legacy VB6 application with data in Oracle 8i, the connection is made using OraOleDB. I remember something about some restrictions in the CursorLocation options. The application is using adUseServer in the option but I recall a problem about that. Could someone give some link to any reference where I could start looking?
Thanks in advance and I'm really apologize because of my English!
Fernando.

I seriously doubt adUseClient causes the client to execute SQL. These:
http://dev.mysql.com/tech-resources/articles/vb-cursors-and-locks.html
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/ado270/htm/mdcstcursorlocationenum.aspcause me to think it's more like CachedRowSet, though I'm not sure.
That's the way database servers work: they execute SQL. The client can't execute the query because it doesn't have the database's tables or indexes. If it had those ...well, it would be the server then.
Optimize your query. Index it. Myself, I'd run away screaming if I had a 50+ -join query. Or I'd try very hard to refactor the query - separate selects, client side data caching, ... And get a database that doesn't hang, they aren't supposed to do that(!!)

Simultaneously Connecting Multiple Tables of the same Database to Textboxes of the same Form using a single ADO Control Code using VB6 Enterprise Edition and MS Access 2007

Iv 10 Tables consisting of atleast 10 fields each in a single Database. Bt, Im only able to connect 1 table at a time to a form using an ADO Control. Im able to add data from table 'student' to text-boxes in my form. Bt, hw can I add data from field(0) of
Table 'Student' to Textbox1 and data from field(0) of Table 'Marks' to Textbox2 using VB6??
This is the current sample coding iv got to connect a single table to a form:
Global con As New ADODB.Connection
Global rs As New ADODB.Recordset
Public Function Connect()
If con.State = 1 Then con.Close
con.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + App.Path + "\bca.mdb;Persist Security Info=False"
End Function
Private Sub Add_Click()
If rs.State = 1 Then rs.Close
rs.Open "select * from student", con, adOpenDynamic, adLockOptimistic
rs.AddNew
rs.Fields(0) = (Text1.Text)
rs.Fields(1) = (Text2.Text)
rs.Fields(2) = (Text13.Text)
rs.Fields(3) = (Text4.Text)
rs.Fields(4) = (Text5.Text)
rs.Fields(5) = (Text6.Text)
rs.Fields(6) = (Text7.Text)
rs.Fields(7) = (Text8.Text)
rs.Fields(8) = (Text9.Text)
rs.Fields(9) = (Text10.Text)
rs.Fields(10) = (Text11.Text)
rs.Update
MsgBox " Record Added"
End Sub
What can I do to add fields from 2 different tables to different text boxes within the same form using a single ado control using vb6 and MS Access 2007??

Limitation on SQL executing select statement from ADO and Oracle 8.1.7.1 OleDB Driver

Hi,
we are running a query with a big dunamic select statement from VB code using ADO command object. When Execute method is called system hangs and control won't return back to the application. it seems to be that there is some type limitation on Query string length. Please tell us if there is any?
we are running Oracle 8.1.7 Server on Windows 200 Server and connecting from a W2K professional, ADO 2.6 and Oracle OLEDB 8.1.7.1 OLEDB Driver.
Sample code:
Dim rs As ADODB.Recordset
Dim cmd As ADODB.Command
Set cmd = New Command
With cmd
.CommandText = ' some text with more than 2500 characters
.CommandType = adCmdText
Set rs = .Execute
End With
when i debug using VB6 and when .Execute line is called system hangs or return a message method <<somemethod> of <<some class name>> failed error.
Any help is appreciated.
Thanks,
Anil

A stored procedure would only slow you down here if it was poorly written. I suspect you want to use the translate function. I'm cutting & pasting examples from the documentation-- a search at tahiti.oracle.com will give you all the info you'll need.
Examples
The following statement translates a license number. All letters 'ABC...Z' are translated to 'X' and all digits '012 . . . 9' are translated to '9':
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'9999999999XXXXXXXXXXXXXXXXXXXXXXXXXX') "License"
FROM DUAL;
License
9XXX999
The following statement returns a license number with the characters removed and the digits remaining:
SELECT TRANSLATE('2KRW229',
'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ', '0123456789')
"Translate example"
FROM DUAL;
Translate example
2229
Also, LIKE '%<string>%' is going to be rather expensive simply because it has to compare the entire string and because it forces full table scans, rather than using indexes. You could speed this sort of query up by using interMedia Text (Oracle Text now in 9i). If you can eliminate one of the '%' options, you could also improve things.
My guess is that your stored procedure is inefficient and that's causing the problem-- 5k rows per table should be pretty trivial.
If you post your query over on the PL/SQL forum, there are better performance tuners than I that might have more hints for you. To get really good advice, though, you'lllikely have to get at least the execution plan for this statement and may need to do some profiling to identify the problem areas.

ODP and ADO and a trigger - problem

I have written a simple trigger to turn on tracing for a session based on the username:
It works fine through sqlplus. The application works when run using JDBC and native(?) java. But when we use hibernate and ODP.net and ADO.net The session goes into a loop of recursive sql and gets an ORA-36 too many recursive levels. I am not a java developer and I am at a loss on how to proceed. It appears to be firing the trigger or have fired the trigger, and then look for global_db_name until it dies.
CREATE OR REPLACE TRIGGER gopal_user_login_trigger
AFTER LOGON ON DATABASE
DECLARE
     user_name VARCHAR2(30);
BEGIN
SELECT username INTO user_name FROM sys.V$SESSION
WHERE audsid = USERENV('SESSIONID') AND audsid != 0 ;
IF UPPER(user_name) = 'GOPALASSETUSER'
THEN
     DBMS_MONITOR.SESSION_TRACE_ENABLE(NULL, NULL, true, true);
END IF;
EXCEPTION
WHEN NO_DATA_FOUND then null;
END;

Hi,
Thanks for the bug number - that helped alot.
Why the global_db_name lookup, I do not know. It appears to be part of the logon processing that follows the trigger.It is, indeed, part of the logon process and is called by internal code so that makes sense now.
If you have MetaLink support, I would recommend opening an SR. One simple thing that I might suggest is to set "enlist=false" in your connect string if you can and test with that.
Thanks,
Mark

MTS, OraOLEDB provider, and Connection Pooling

I have read through "Using Microsoft Transaction Server with Oracle8" (http://technet.oracle.com/doc/oracle8i_816/nt.816/a73029/prog.htm#1082299) and the OraOLEDB provider document, and found little coverage in regard to the subject of "Connection Pooling." Could you point me to additional documentation and code samples that would help guide me in designing my application.
I am designing a web based distributed application subsystem with MTS/COM+, OraOLEDB provider (8.1.7.2.0), Oracle Services for MTS (8.1.7.0.0) and Oracle 8i (8.1.6). A major requirement of this subsystem is that it scales well as it is utilized by more and more applications and users. This requirement could be accomplished much easier if the OraOLEDB Provider provides Connection Pooling. Much of the documentation I have seen from Microsoft describes Connection Pooling using ODBC. The documentation from Oracle discusses Connection Pooling with OO4O or OCI. Does the OraOLEDB Provider provide Connection Pooling? If so could you point me to additional documentation and samples?
Thanks,
Bryan Wood

I am facing the same issue. This is strange, no one has responded to this for a year. What does it mean? It sux so bad that no one uses OmniPortlet? It's clear when you execute a sql thru this stupid OmniPortlet it opens a connection and never releases it. I have seen this by turning off everything and keep refreshing the OmniPortlet.
What bothers me more is that there seems to be no freakn documentation on this especially around how to do this from the console and how to use the jndi datasource. There has to be a way. Please help us out on this either from inside or outside oracle.
The world class Oracle support seems to be a joke.

Database fileds are not coming when connecting with ado and they are coming when connecting with odbc

Post Author: yagya
CA Forum: .NET
Hi , I am using crystal report XI R2 in visual studio 2005 . Backend is sql server 2000. I have made a connection with odbc connectivity and using dsn. I am using a stored procedure as datasource of report. It is working fine all the database fields are available. Now when i try to connect with the ado connection having same stored procedure as datasource of report , I am not getting data fields. I dont know where is the problem in my stored procedure or in report. But when i connect through system dsn using odbc connectivity everything is working fine. A MAP filed dialogue box appears when i try to change the datasource location to ado from odbc.

There is a barely acknowledged issue. For Mac users Apple has released an update to the app, but for iOS users the recommendation is for users to update their ipad to the most recent operating system.
There may be a fix coming for iOS6 users (which seem to be many of those having problems) or there may not be. If your ipad isn't up to date then you can update it and see if that helps, or if you don't want to update then you may want to wait and see if there is either a fix or if it fixes itself.

Problems writing BLOB data into O8i (ADO and AppendChunk)

We have a table where you want to store bianry data (BLOBs). I
have used the LONG RAW datatype to store this information. Here
is the code for the table:
CREATE TABLE "CONTENTBLOBTABLE" (
DIGEST NVARCHAR2(40) NOT NULL,
BLOB LONG RAW,
CHECK (DIGEST IS NOT NULL),
PRIMARY KEY (DIGEST)
Then we try to update this table with ADO 2.6 on a Windows 200
machine with Oracle ODBC driver. Here is the relevant code
snippet:
// set the value of the field
pRs->AddNew();
pRs->Fields->GetItem("DIGEST")->PutValue(strDigest);
pRs->Fields->GetItem("BLOB")->AppendChunk(varBLOB);
if(!pRs->Update())
C_LOG_CRITICAL(L"CC_CS_DAL::WriteBLOB - pRs->Update failed");
*error = C_CS_CBT_ERROR;
pRs->CancelUpdate();
pRs->Close();
m_pConn->Close();
m_spObjectContext->SetAbort();
return S_FALSE;
OK, NO error occurs: no exception, HRESULT return values are all
OK, method completes.
BUT: there is no data in the table!?!?! When querying the exact
same table we get an empty result!
Any ideas please?
Thanks,
Christian

Dynamically change Database, Server and Command From VB6

I have a crystal report which connects to an iSeries box via an OLE DB datasource, however i need to have this same report conect to two different iSeries, with the tables for the sql (command) located in two different libraries.
Is it possible to change the command in vb (as well as the connection etc) so i can change the box and library t execute the sql against at run time ?

Hi,
From VB 6 you can change the report's datasource. Depending on the version of Crystal you are using, you may be able to change the SQL but if the data is the same on all the iSeries boxes then you shouldn't have to.
Again, the way to do this will depend on the version of Crystal you are using and the method you are using to call the reports.
Basically, there is a property in the reporting object that will allow you to logon to the database. This would give you the same functionality as if you were in the Report Designer and went to Database | Set Database Location.
Without knowing the version of Crystal and the method for calling the report, it's a bit difficult to get into specifics.
Good luck,
Brian

Connection error with Crystal Report XI, VB6 and Sybase ASE15

Hello !
I have an error #4002 when I want to launch a report in VB6 with the ActiveX Crystal Report Viewer.
I use Sybase ASE 15 with an ODBC link and the reports run stored procedures.
This error seems to be an authentification error, but I don't know what parameters are missing or wrong...
- My reports works well in the report designer.
- The reports connected to a text file or an ADO recordset work in VB6.
- The Verify Database works in design mode in VB6.
- The problem is the same with tables, stored procedures, SQL and with or without parameters...
- I tried to connect the report to a DataEnvironnment but I get the same error.
The problem appears when I use the Crystal Wizard to create a form automatically AND when I create objects directly in code like :
    Dim crapp As CRAXDRT.Application
    Dim oReport As CRAXDRT.Report
    Set crapp = New CRAXDRT.Application
    Set oReport = crapp.OpenReport("C:\myreport.rpt")
    CRViewer.ReportSource = oReport
    CRViewer.viewReport
Please help !

Hello,
I don't see any database logon code in what you posted. You need to log onto the database at runtime since Crystal Reports will never store passwords.
You can download and review the [Connection Properties|https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/00635998-751e-2b10-9cba-f50ee1e4ef81] document for more information on how to log onto your database at runtime. This document was written for CR9, but it's the same for CR10, CR XI (v11.0), and CR XI R2 (v11.5).
I hope this helps.
Sincerely,
Dan Kelleher

Classic ASP - "ORA-01722: invalid number" using OraOLEDB.Oracle driver

I am working on doing some maintenance updates to a Classic ASP website, and I need to be able to run an insert/update statement for putting values into a lookup table. I am currently running into an "ORA-01722: invalid number" error when trying to use ADO and bind variables for my insert statement.
Below is an example of a table that I am having problems with:
CREATE TABLE "MATMGR"."TEST_SWING_TABLE"
(     "TABLE1_ID" NUMBER(4,0) NOT NULL ENABLE,
     "TABLE2_ID" NUMBER(4,0) NOT NULL ENABLE,
     CONSTRAINT "TEST_SWING_TABLE_PK" PRIMARY KEY ("TABLE1_ID", "TABLE2_ID")
USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255

PCTINCREASE 0 FREELISTS 1 FREELIST GROUPS 1 BUFFER_POOL DEFAULT)
TABLESPACE "USERS" ;
Here is some snippet code of the basic functionality I am trying to get to work:
''START CODE''
Dim connDb, cmdDoseInsert
Set connDb = Server.CreateObject("ADODB.Connection")
connDb.CursorLocation = adUseClient ' Setup to return RecordSet
connDb.ConnectionString = "Provider=OraOLEDB.Oracle;Data Source={host};User ID={user id};Password={password}"
connDb.Open()
Set cmdDoseInsert = Server.CreateObject("ADODB.command")
Set cmdDoseInsert.ActiveConnection = connDb
cmdDoseInsert.CommandType = adCmdText
cmdDoseInsert.NamedParameters = true ' Set the command object to use named parameters
cmdDoseInsert.Prepared = true
cmdDoseInsert.CommandTimeout = 0
cmdDoseInsert.CommandText = "INSERT INTO TEST_SWING_TABLE (TABLE1_ID, TABLE2_ID) VALUES (:P_TABLE1_ID, :P_TABLE2_ID)"
cmdDoseInsert.Prepared = true
cmdDoseInsert.Parameters.Append cmdDoseInsert.CreateParameter("P_TABLE1_ID", adNumeric, adParamInput)
cmdDoseInsert.Parameters.Append cmdDoseInsert.CreateParameter("P_TABLE2_ID", adNumeric, adParamInput)
'... START: While Looping
     cmdDoseInsert.Parameters(0).Value = {some numeric value}
     cmdDoseInsert.Parameters(1).Value = {some numeric value}
     cmdDoseInsert.Execute
'... END: Looping
''END CODE''
What I have been able to find out so far is that there is some type of issue with numeric values getting translated right when sending two and retrieving from Oracle in ASP. So, does anyone have any thoughts on how to resolve this as I would like to use parameterized SQL to improve application performance?
I am connecting to a developmental server running Oracle 9.2

Ok, in my slightly larger example I found out that for what ever reason my named parameters are not being enforced, and so I had to make sure that the parameters were in the same order as they appeared in the SQL. To be on the save side, I did this when they were added as well as when I was assigning values to them.
Can anyone tell me if this is an Oracle issue or a ASP issue?

JVM Crash When Using JNI and COM

I'm trying to call a DLL compiled from VB6 source code that I do not have access to. The VB6 code simply retrieves data from a DB2 database using ADO and my client code grabs that data and marshals it to my Java code. I'm attempting to achieve this using JNI and COM (without a third-party bridge). It works 75% of the time, but the other 25% of the time, the JVM crashes with the usual Hotspot crash log containing an access violation exception. However, I don't know what in my C++ code (VC++ 8) could be causing this except for passing a "wild" pointer to the code lying underneath the COM object interface. If that is the case, I don't know how I am doing that.
The Java code that is calling my native method is running on Tomcat 5.5.25 and just to be safe, I am not allowing multiple threads to concurrently call the method in my JNI DLL (though I realize that this will kill performance). Once I can get past this problem, I'll do the COM interfacing on a worker thread in my native code so I don't screw up CoInitialize and CoUninitialize calls in the case the same thread is concurrently executing multiple calls to my native code.
I've noticed that in most cases, the JVM crashes during my call to the pClsAccount->OpenConnection method. However, my DLL isn't what is listed on the top of the call stack, which is why I suspect the passing of a wild pointer, though I'm just taking a guess at that. Does anyone have an idea as to what's going on ?

OraOLEDB.Oracle generates error when retreiving a table with anydata col

Hi,
I use OraOLEDB.Oracle to connect from VB6 to oracle, and ADODB recordsets.
I have a procedure that returns a table (using a cursor), the table has a column of type sys.anydata.
I get this error: ROW-00004: Invalid column datatype
I have to mention that it works excelent for anything that does not contain sys.anydata.
I use Oracle 9.2.
Thanks in advance,
pesq

I tried your solution, but it didn't work. I get an error (incorrect column number):

The code is following:
                    String query = "BEGIN insert into movement (doc_number) values ('abc') returning id into :?; END;";
                    OracleCallableStatement cs = (OracleCallableStatement) c.prepareCall(query);
                    cs.registerOutParameter(1, OracleTypes.NUMBER);
                    cs.execute();
                    LOG.debug("result:"+ cs.getInt(1));
I used Oracle database 10.2.0.1 with jdbc thin driver ojdbc14.jar. Could you point out your configuration?

Connecting to an Azure SQL Database from VB6

We have an old Application that is accessing a database located on a client site. We currently access this database using ADO and SQL Authentication. Would it be possible to migrate to Azure SQL Server and connect to it from the VB6 Application by just changing
the connection string?

Yes, but you have to make sure that you are not using any features that SQL Azure doesn't support. And make sure that the SQL Azure server address is open for connection from outside. You also need to be concerned about data security.
