Question

As mentioned in title. I wanna know that does SQL Server can partially execute a SQL like oracle do? means server wait client to process the data in last network packet and then fill next packet I noticed that when you execute a select statement in SQLServer Management studio, you can get the first rows immediately while the statement is still running. But I cannot get this in ADO component. All I can think about is use server-side cursor and use non-keyset type cursor. But ADO use sp_cursoropen and sp_cursorfetch to do this. Not using cache size like sql*plus do. It mains it is client side behavier, not like the phenomenon in SSMS. I want know why.

Answer 1

It appears that the corresponding feature in SQL Server is known as Array Fetch Size. (Discussed here, for example.)
