What database type to choose? - Database Discussion Boards

How the heck did I get here? There seem to be eddies in the Space-Time continuum.

Sorry I can't help with specific SQL Server stuff, but in an Oracle database I would do something like the following;

create or replace procedure FindBillingID
as
cursor BillingID /* define your Recordset here */

begin
for BillRec in BillingID cursor loop
uspBillClient(BillRec.BillingID);
end loop;
end FindBillingID;

The uspBillClient is then pretty much as you wrote except that it's IN parameter is of a different type and it get's repetitively called.

Hope this is kinda what you are looking for.

I am writing a VB app (called FISWDC) with a data environment (called DataEnv). I
believe I should be able to do:
DataEnv.Connection.connectionString = "File Name=" & App.Path & "\FISWDC.UDL;"
or, at least
DataEnv.Connection.connectionString = "File Name=FISWDC.UDL;"
or maybe
DataEnv.Connection.Open "File Name=" & App.Path & "\FISWDC.UDL;"
or something like that, but whatever I do I just keep getting the error
"The parameter is incorrect"
or
"Connection was denied. New connection you requested has different characteristics than the one already in use."

Can anyone help?

Have you double-checked the UDL-files contents?

Try using the UDL on a clean connection object:
Dim cnn As New ADODB.Connection
cnn.Open "File Name=c:\test\file.udl"

Hi,

I'm looking for a young SQL programmer that would be interested to work on a new exciting project. Should speak german or french.
if you're interested, please drop me an email: pierre@runser.com

Thanks,
Pierre Eek! | :eek:

As a former (and current) UNIX programmer, I am finding myself in a state of confusion when it comes to DB programming in windows. In UNIX I get the libraries I need to talk to the database and use SQL statements to do it all. I connect, query, then parse the results. I'm looking for something as simple to do un Windows. If it helps, I'm looking for something very php (www.php.net) like in syntax: connect(params), execute(sql statement), fetch_array(results), disconnect(). Most important no note that the fetch_array returns tabel data as record=fetch_array(query_result); record[field]="some val". Alternative to that is fetch_row which you can use the index (column number) of the field to get that value. Is there anything like that in Microsoft? Do I have to use classes of CDatabase and CRecordset? It looks like I have to jump through a lot of hoops to get something simple working.

Secondly, what are the installation requirements for the particular methods? Must I always require Microsoft Access be installed? Under UNIX I can make such a requirement because there always is a UNIX admin handy to install it. But on a PC I cannot make that assumption. I have to assume that any inexperianced user can handle it. Which also raises the question, how do I initialize a database under windows? Could I use hard coded SQL statements?

Thanks in advance

Take a look at http://download.microsoft.com/download/vc60pro/sample/1/WIN98/EN-US/Adovc1.exe

It's a simple sample using the #import directive, which makes it pretty easy to use ADO to do all the stuff you want...

Simply include MDAC in your setup's, it can be downloaded from http://www.microsoft.com/data/

All database drivers are included in MDAC, so as long as you are using Access databases or SQL Server, you know the drivers are there...

Hope this helps.

Given 2 machines, one running IIS, the other SQLServer, with connections to SQLServer via named pipes (as opposed to TCP/IP) on a LAN, is there any way to determine why a connection to the SQLServer from the Web server would be failing at random times?

The error messages reported by SQLServer and IIS are less than inspiring. Just wondering if anyone else has come across this random fail situation before.

cheers,
Chris Maunder

Just chage the client on both machines to use TCP instead of Named Pipes and the problem is gone Smile | :)

(I hope)

Well, at least, if the errormessages is something about a "Overlapped Result" it works...
