export data from Excel to Oracle using ADO

Hi
I have an excel application and I am starting to work with Oracle.
when the user pushes a button the data in the sheet need to be updated in the Oracle DB. I created a loop on all records in the excel sheet, and I am using a recordset.

[VBA]dim RS as ADODB.Recordset

for lRow = 1 to 10,000
RS.AddNew
RS(1) = cells(lRow,1)
RS(2) = cells(lRow,2)
...
RS(200) = cells(lRow,200)

RS.Update

next lRow
[/VBA]
I used such code in the past with SQL server and it was very fast.
now that i use it for Oracle it takes almost 2 minutes for 10,000 records. that is a lot of time for my application. is ther a way to make it faster?

Are you using Oracle Drivers or Microsoft drivers for Oracle or an OLEDB Provider?

the Provider in the connection string is MSDAORA

hmmm. in my experience with Oracle, I have not felt the Provider was very efficient, and believe it or not I got better performance from the Microsoft Driver than Oracle's. Just .02

how do i obtain this driver?
can you write the syntax in the connctions string?

How to get the driver: http://support.microsoft.com/kb/175018
How to write the connection string: http://www.connectionstrings.com/?carrier=oracle

Provider=msdaora;Data Source=MyOracleDB;User Id=myUsername;Password=myPassword;

My bad! :motz2: The OP was already using the driver; I think the version in the snapshot I posted is MDAC 2.6 or greater where MS made some improvements. Stan

as an FYI - you can google OraOLEDB.Oracle.1 which can be downloaded. It recognizes the newer Oracle Data Types.

[vba]
oracleConn.ConnectionString = "Provider=\"OraOLEDB.Oracle.1\";
User ID=scott;Password=tiger;
Data Source=yourSource;
Extended Properties="";
Persist Security Info=False";

[/vba]

Thanks. I tried this:
Provider="OraOLEDB.Oracle.1";
and in the example I gave in the original message I was able to reduce the speed from 1:05 to 00:27 seconds!
Some parts of my code which worked before are not working with the new driver but I hope i can get them all to work.
