Some enhancements have been made to the SQL Server Native Client OLEĭB provider which extends the core features of OLE DB. To enable ADO to use new features of recent versions of SQL Server, And the SQLNCLI10 provider has been updated, so I guess it is more tuned. Some kind of data (like var(maxchar) or Int64) is told to be best handled. Like always, it will depend on the data processed.īut it is IMHO recommended to use best fitted provider for your database. If you specify the SQLOLEDB provider, you'll use the generic SQL Server 2000 + protocol.Īs such: ADO -> OleDB -> SQLNCLI10 provider -> MS SQL Server (MSSQL 2000, 2005 or 2008 protocol)ĪDO -> OleDB -> SQLOLEDB provider -> MS SQL Server (MSSQL 2000 protocol)Ībout performance, I think you won't have a big difference. If you specify the SQLNCLI10 provider, you'll use the latest version of the protocol.
#SQL SERVER NATIVE CLIENT 10 FASTER OLEDB DRIVER#
SQL Server Native Client combines the SQL OLE DB provider and the SQL ODBC driver into one native dynamic-link library (DLL).įrom my understanding, ADO is just an Object Oriented application-level DB layer over OleDB. SQL Server Native Client is a stand-alone data access application programming interface (API), used for both OLE DB and ODBC, that was introduced in SQL Server 2005. I'm not necessarily looking or asking for ways to improve performance - I just need to know what are the differences between the drivers. This is specifically using ADO via the TADOConnection component and TADOQuery as well. But what else is going on behind the scenes? And how does that affect how Delphi uses these drivers? So really, what are the differences between the two? I do know that OLE is very flexible and supports many different database engines, whereas Native Client is specific to SQL Server alone. Here's a sample of my load tester, numbers on very bottom are averages. I've also tried adding some things to the query - such as order by Val where Val is a varchar(100) field. After receiving the data, I do another load of looping through the results (using while not Q.eof. For example, I do select * from SysTables and this table has 50,000+ records. The load tests consist of very small queries which return very large datasets.

Of course the server does the majority of the workload, but I'm interested in the time it takes between the data coming into the PC to the time the data is accessible within the app. Sometimes one is faster, sometimes the other is, no matter what the query may be (simple select, where clause, joining, order by, etc.).

So I put together a utility to do a load-test between the two - and am getting mixed results.

Or client tools and also avaialble by separate download ( ).īe aware that Microsoft has announced that OLE DB will be deprecated in SQL Server 2012 for SQL Server relational database access in favor of the SQL Server Native Client ODBC driver ( ).īut today, tools like SSIS use OLE DB heavily so you'll need to stick with OLE DB until the toolset provides first-class ODBC support.I have been told that SQL Native Client is supposed to be faster than the OLEDB drivers.

As Venkataraman mentioned, SQL Server Native Client 10.0 is recommended for new development. Modern Windows operating systems as part of Windows Data Access Components. SQLOLEDB has been deprecated for some time but is provided for backwards compatibility in Both the SQL Server Native Client 10.0 OLE DB provider (SQLNCLI10) and SQL Server OLE DB driver (SQLOLEDB) are OLE DB providers shipped by Microsoft.
