Sometimes one is faster, sometimes the other is, no matter what the query may be (simple select, where clause, joining, order by, etc.). 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

问题 I have a c# website that allows a client to connect directly to a remote SQL Server database from their PC , bypassing the web server, by using a 3rd party ActiveX control. I was originally using the SQLOLEDB provider and it was working fine. The clients are in an internal network (using Windows machines and Internet Explorer) and the website is not intended for exposure to the general internet. I had to upgrade from using the SQLOLEDB provider to the SQLNCLI10 provider to cater for the new
