Hi,
Unlike in Oracle we don't option to set update frequency for MViews in SQL SErver, so just curious how it works in there.
I have MView (aka Indexed view with schemabinding) with 1M rows, and this morning at 9am got .5 million load of new rows in underlying tables.

Will I have 1.5 million if I do select at 9.05 am? Who controls that refresh, or upon first Select it still do sync?

Thanks
Mario

It's updated as part of the transaction which modified the base tables.

You'll have 1.5 million if you query one microsecond after the commit for the insert into the base table.
