dear all:
I'm trying to use OLE DB to access the SQL Server instead of ODBC(MFC) which I was quite familar. Here is some simple codes I used to open data source:
CString m_username,m_password;
...
...
CDBProSet m_dbproset;
m_dbproset.AddProperty(DBPROP_INIT_DATASOURCE,L"SQL_SERVER_HOSTNAME");
m_dbproset.AddProperty(DBPROP_AUTH_USERID,m_username);
m_dbproset.AddProperty(DBPROP_AUTH_PASSWORD,m_password);
m_dbproset.AddProperty(DBPROP_INIT_CATALOG,L"DEFAULT_DATABASE");
CDataSource m_datasource;
m_datasource.Open(L"SQLOLEDB",&m_dbproset,1);
When I call CDataSource::Open menthod I was informed that some OLE DB process make mistake.
Can anyone tell me is there anything wrong with my codes or I missed sth?
Thank you very much.

Maybe if you posted the actual error message someone could help...

As we known,we can get record set like the following:
_RecordsetPtr pRst = pCmd.Execute(0,0,"ss");//pCmd is a ADO Command object,"ss" is the name of stored procedure to be executed.
and get return value or output parameter after call pRst->Close();
but when the stored procedure has no recordset,pRst will be a closed Recordset,it can't be close again.This time I can't get the return value or output value,Why?
You can send mail to me discussing this problem:

Hi there,
I'm trying to use ADO in my app. Here is an example query:
SELECT [Translation] FROM TRANSLATED_OTHER WHERE [Language] = 'Chinese' AND Text = 'Length';
If I call Fields::GetItem("Translation") on my RecordSet I get back the correct value. However if I use Fields::GetItem(0) a _com_error is thrown and I get the following error:
Item cannot be found in the collection corresponding to the requested name or ordinal.
What am I missing?
Thank you.

I don't quite remember but it may be that Item index in Recordset starts from 1 instead of 0.
Try using Fields::GetItem(1) instead.

Thank you for the suggestion, unfortuantely I already tried that to no avail.

Carlos Antollini posted a nice aricle with a wrapper class for ADO
here[^]. His wrapper method for Fields.GetItem(int index) worked well for me. Perhaps inspecting his code would answer your question.

I've got rather a lot of cleaned data that has the title,first and last names stored as a single string in one column - is there a simplish way to split this out into 3 columns. e.g something like this ?
select splitTitle(name) as title, splitFirst(name) as first, splitLast(name) as last from myTable
Also what books do people recommend for learning this kind of stuff ?
Many thanks for any help

Hi Jerry,
You can split the values using substring and charindex in SQL Server. I guess, you have to write a stored procedure to split them based on delimiter by passing concatinated string and delimiter and get title, first and last names. I can help you in this, if you try out something..
Thanks,

Anyone know of a free/cheap tool that will connect to SQL server and output a simple report showing the tables and columns (including name, type, size and description)? Choosing the tables would be nice, as would the ability to list indexes.

I have an application which reads large CSV files and displays them in a DataGrid.
I have many methods for updating the DataTable EG Add/Delete/Rename/Fill Columns along with Math Functions EG Divide/Multiply ETC.
The question I have is where should the logic reside for updating the table? What object/s or class/es should be responsible for performing the upadte?
At the moment, I have several forms for displaying the options associated with the relevant functions and pass the DataTable to peform the update but this is getting messy.
I want to re-structure the application before it gets to big and at the same time seperate the data from the interface so the data source becomes transparent to the front end.
Is this possible and what is the best approach?
Regards

I was reading up on it and found a few ways it can be done...OLE DB, DAO, ADO.net, etc. Which is the best one to use to communicate with the data source or is there something else? Would an MS-Access data source be the best approach or does it even matter what kind of data source you have?

Hi
We have a client who runs a legacy 4GL system, with a C-ISAM backend (I think it is Informix).
The system is hosted ona linux box within the network
Now the developer of this system provides a READ-ONLY ODBC driver! But we have to manipulate data in this database, but I cannot find any drivers that I can use to talk to this system, and the developers have been less than helpful to say the least!
Any help would be greatly appreciated!
Thanks in advance!

If it's really C-ISAM, then it is informix. I'm pretty sure that you should be able to find (i.e. buy) ODBC drivers for the system. I did some work a while ago (OMG! over 3 years) doing just this kind of thing.
The alternative, which is almost too ugly to contemplate, would be to write a linux server process that uses C-ISAM directly, and have that do your manipulation, via something like normal sockets.
A third alternative is to have the linux box expose the raw data files via SAMBA, and use something like Byte Designs' D-ISAM product.
