    MS SQL Date indexing

    Does MS SQL uses index when searching by date column? For example does mssql for such query will use date_field index:
    Code:
    select * from table where date_field between 'date1' and 'date2'
    Thanks in advance,

    I don't see why it wouldn't, assuming someone actually created the index for that field.
    You do need to create the index first, though. It doesn't index automatically, I don't think...

    If this post contains any code, I may or may not have tested it. It's probably just example code, so no getting knickers in a bunch over a typo, OK? If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there. I'm giving examples, not typing up your whole app for you. You run code at your own risk.
