Dates Explained
Here are some of the ways dates can be output.
declare @date datetime set @date = getdate() select @date as SampleDate, datepart(year,@date) as 'year', datepart(month,@date) as 'month', datepart(day,@date) as 'day', datepart(week,@date) as 'week', datepart(quarter,@date) as 'quarter', datepart(dy,@date) as 'day of year', datepart(weekday,@date) as 'weekday', datepart(hour,@date) as 'hour', datepart(minute,@date) as 'minute' , datename(month,@date) as 'month name', datename(weekday,@date) as 'weekday name', 'fiscal year' = case when datepart(month,@date) >= 7 then datepart(year,@date) + 1 else datepart(year,@date) end, CONVERT(varchar(12), getdate() ,112) as 'today date as integer', CONVERT(varchar(12),DATEADD(d, -7 ,getdate()),112) as 'lastweek date as integer', CONVERT(varchar(12), getdate() ,108) as 'time', REPLACE(CONVERT(varchar(12), getdate() ,108),':','') as 'time as integer', dateadd(d,-1, cast(month(dateadd(mm,1,getdate())) as varchar) + '/01/' + cast(year(getdate()) as varchar)) as [Last day of month], DATEADD(D,1, cast(month( getdate() ) as varchar) + '-' + cast(day( getdate()) as varchar) + '-' + cast(year(getdate() ) as varchar) ) as [Midnight Tonight] declare @tim varchar(8) set @tim = REPLACE(CONVERT(varchar(12), getdate() ,108),':','') select @tim, case when len(@tim) >= 5 then substring(@tim,len(@tim)-5,2 ) + ':' + substring(@tim,len(@tim)-3,2 ) + ':' + substring(@tim,len(@tim)-1,2 ) else @tim end
Where are tables located in database files?
This uses indexes to locate the files.

SQL: Last Day Of Month
For any date go back a month, then add a month to it.
SELECT [dtMonthLastDay] = DATEADD(MONTH, DATEDIFF(MONTH, -1, GETDATE()), -1)

What are all those old tempdb temp tables?
SQL Server caches the definitions of temp tables and table variables, to reduce the load on the system catalog in tempdb on busy systems which creates a lot of temp tables. Typically they have a name that starts with # and is followed by eight hex digits. -Erland Sommarskog
SQL Server Temporary Table Caching
This tip will describe the condition to allow caching of a SQL Server temporary table and a demonstration to benchmark the performance between a cached vs. non-cached temporary table.

SHARE permissions vs. SECURITY tab
Here’s a great way to think about it, quoted from around the web:
Sharing only opens the door, security lets you in the door.
Standard practice is to allow everyone on sharing, and restrict access with security permissions. This keeps management simple as the most restrictive permissions apply between the two.
