They are identical: BETWEEN is a shorthand for the longer syntax in the question that includes both values (EventDate >= ’10/15/2009′ and EventDate <= ’10/19/2009′). Use an alternative longer syntax where BETWEEN doesn’t work because one or both of the values should not be included e.g. Select EventId,EventName from EventMaster where EventDate >= ’10/15/2009′ and … Read more
You can find the day of week and do a date add on days to get the start and end dates.. DATEADD(dd, -(DATEPART(dw, WeddingDate)-1), WeddingDate) [WeekStart] DATEADD(dd, 7-(DATEPART(dw, WeddingDate)), WeddingDate) [WeekEnd] You probably also want to look at stripping off the time from the date as well though.
There are several considerations when writing a query using the IN operator that can have an affect on performance. First, IN clauses are generally internally rewritten by most databases to use the OR logical connective. So col IN (‘a’,’b’,’c’) is rewritten to: (COL = ‘a’) OR (COL = ‘b’) or (COL = ‘c’). The execution … Read more

Foreign Keys are a referential integrity tool, not a performance tool. At least in SQL Server, the creation of an FK does not create an associated index, and you should create indexes on all FK fields to improve look up times.
You could cast your result as numeric(x,2). Where x <= 38. select round(630/60.0,2), cast(round(630/60.0,2) as numeric(36,2)) Returns 10.500000 10.50
A “Login” grants the principal entry into the SERVER. A “User” grants a login entry into a single DATABASE. One “Login” can be associated with many users (one per database). Each of the above objects can have permissions granted to it at its own level. See the following articles for an explanation of each Principals … Read more
