Did anybody perform such migration: from Personal Oracle8 (WinNT) to Oracle9i (Linux)?
currently I've got only one problem: some packages, that were normally compiled on Oracle8 cannot be compiled on Oracle9i. Error is PLS-00593: default value of parameter "ParamName" in body must match that of spec. But package header and body are wrapped. So I cannot check default values of parameters... Any ideas?...
I see two possible ways to resolve this: try to find migration utility or find UNWRAP utility to unwrap package body and correct param values.
Thanks beforehand,
Serge.

I have an app which uses DAO.
It works perfectly in most scenarios, except on Win2K when logged in without admin privelleges.
Without admin privelleges the following error is thrown when attempting to open the database:
> ErrorMessage = Unable to initialize DAO/Jet db engine
> ErrorCode = -2147221164
> Scode Code = 340
> Scode Facility = 4
> Scode Severity = 1
Can anybody help shed some light on the cause?

According to MSDN, errorcode -2147221164 (0x80040154) is "Class not registered". I'd suggest that DAO hasn't been installed correctly.

Hmmn... interesting. Thanks, btw how exactly did you determine that error message? I search MS-KB endlessly!
Sadly I've installed the latest MDAC and the error remains.
Clearly I can't install MDAC with normal user privelleges so I logged in as a normal user and installed it using Run As with Admin privelleges.
I have absolutely no idea how to fix this, let's hope it doesn't happen on customers' machines!

I believe the Jet db engine is not included with the newest MDAC 2.7 (or anything above 2.5).
you have to download it as a separate install.

Hmmn I assumed DAO calls would now be routed through their new interfaces.
I guess you could be right, I may need to install the Jet engine seperately.
Thanks

I have a table which has a field "ID". The default ID of the field calls the newid() function and generates a GUID. This all works fine.
I would like to return the new record ID to my app after adding a record via ADO AddNew. How can I do this. I have tried trying to get the value from the field after the call to AddNew but it returns a VT_EMPTY. I've tried doing it after the Update call but that is also VT_EMPTY.
This is the code I'm using,
Recordset.Create();
Recordset.Open("calls", *m_pConnection, littleADO::adOpenDynamic,littleADO::adLockOptimistic,littleADO::adCmdTable);
variant_t vt;
try
{
Recordset.AddNew();
Recordset.m_pRecordset->Fields->Item["Ref"]->Value = pData->m_sRef.c_str();
Recordset.m_pRecordset->Fields->Item["PoliceForceID"]->Value = pData->m_sPoliceForceID.c_str);
Recordset.m_pRecordset->Fields->Item["DivisionID"]->Value = pData->m_sDivisionID.c_str();
Recordset.m_pRecordset->Fields->Item["LocationID"]->Value = pData->m_sLocationID.c_str();
Recordset.m_pRecordset->Fields->Item["CustodyID"]->Value = pData->m_sCustodyID.c_str();
Recordset.m_pRecordset->Fields->Item["CustodyDesc"]->Value = pData->m_sCustodyDesc.c_str();
Recordset.m_pRecordset->Fields->Item["CallTime"]->Value = COleVariant(pData->m_CallTime);
Recordset.m_pRecordset->Fields->Item["Status"]->Value = pData->m_nStatus;
Recordset.m_pRecordset->Fields->Item["UserName"]->Value = pData->m_sUserName.c_str();
// try and get the id here
vt = Recordset.m_pRecordset->Fields->Item["ID"]->Value;
Recordset.m_pRecordset->Update();
vt = Recordset.m_pRecordset->Fields->Item["ID"]->Value;
}

I've changed my code to use a stored procedure which returns the value of the ID back as an output parameter. This works pretty well.
I'd still be interested to know if it is possible via AddNew though.

Hallo
Does anyone know how I can check, if a dBase-recordset is deleted while using ADO?
Thanks.

Hi, I don't know how to detect deleted record via ADO, but I know the file structure and there is asterisk in the dbf file.

I found an interesting article comparing various databases, MS SQL among them. They mainly used JDBC to test the dbs, and surprise surprise, MS SQL didn't do so hot. But, when MS SQL was used in an all MS environment, it more than held its own.

I have an Access database with some tables . From a web page (using ADO )the records in a table can be modified or new records can be added .
From a Visual C++ (using also ADO) program I have to monitor these changes .
How can I do this ??
At a new record insertion I tried to read the recordcount from table , but it is increased only after 2-3 seconds after the insertion performed at web page.

Wrote a front end in VC++ to a small Access 2000 database utilising ODBC. When I add a new row to a table and then read through the table again to display the contents on screen the new row is missing. If I read the table a second time the new row is there. I Open and Close the database connection after each action so I don't believe that I am reading the data from cache.
Any idea why the new row is missing when I read throught the table immediately after adding the row?

Just wondering what I need to add to a VC++ program to allow me to directly access an SQL Server database using Transact SQL. Is there an SQL Server SDK?

You could add an ADO class found in CodeProject somewhere and in there you can create strings which consist of your T-SQL then you get a recordset back. you dont need an sql sdk.
I hope thats what you wanted;)

Hello All,
This is a pure newbie question on use of Oracle database. I need to design a system
to access Oracle database on a Windows client. We only have Oracle installed on
Windows server.
Can someone help me with the options available, if any?
Do I have to install a client version on the Windows machine?
Will the client version access the database on Unix Machine?
Any another information will be highly appreciated.
Best regards,
Paul.

You should install oracle client on every machine from wich you will connect to Oracle. Location of Oracle (WinNT or Linux) is not important. You just have to configurate tnsnames.ora files on client machines. Usual practice is design single Oracle client driver that will communicate with Oracle and all client applications will communicate with him. So you don't need to install oracle client on all machines, but you need to realize your own transport protocol to communicate client applications and your driver.
Good Luck,
Serge

Thanks so much for the information. I am also looking at the 9i internet features too. The main problem was that the customer was limiting us to only HTTP access of the database.

Hi guys:
I have two question about ADO.Net
1.How or where can I set the "Curser type"?
2.I have datagrid that connect to database with sqlDataAdapter,and sqlConnection.
In VC++ I could set the propety of grid to 'Allow Update' or 'Allow Delete' 'AddNew',
Now in ADO.Net how can set the grid as "Updatable" or "readonly"?
Thanks

I don't think you'll find that property, if you use a DataSet it will be always Client Side
<help>
Property Value
true if the grid is in read-only mode; otherwise, false. The default is false.
Remarks
In read-only mode, the grid can be scrolled, nodes can be expanded or collapsed, and so on, However, no additions, edits, or deletes may take place.
The DataGridColumnStyle also has a ReadOnly property that can be set to true to prevent data from being edited, on a column-by-column basis.
The ReadOnly may be set to true if you want to prohibit the user from editing the data directly in the DataGrid. For example, you may want to let users to see all columns in a table, but allow them to edit specific fields only through TextBox controls on a different form.
