SQL Server memory configurations for procedure cache and buffer cache
The larger the procedure cache area, the more execution plans SQL Server can keep in memory, which reduces the amount of time the system takes to prepare the query for execution.

SQL Server IO Latency
Reply Peter says: May 28, 2013 at 8:15 am Hello, Since the dmv gives cumulative numbers, I persist the results each hour and compare sequential results. Just asking Reply Paul Randal says: October 8, 2014 at 10:34 am You have to remember that the DMV is the aggregate over the time the database has been online, so the average may mask any transient latency spikes
PostgreSQL vs. MS SQL Server
The computers on the International Space Station (the most expensive single man-made object in existence) were moved from Windows to Linux in 2013 "in an attempt to improve stability and reliability". A data analytics platform has to be able to look at data from a wide variety of systems and produce outputs that can be read by a wide variety of systems
Configuring SQL Server memory settings
Certain builds of Windows 2000 and Windows Server 2003 contained a potentially serious memory corruption problem which affected SQL Server more than other applications, mainly because there are few applications that run on Windows that can utilise the amount of memory SQL Server does. DBCC MEMORYSTATUS Running the above command outputs the memory usage of SQL Server including how that memory is allocated, so unless you need to know how and where that memory is being used, the output it generates can be a bit bewildering
I do not use Access) but I assumed that it would more generally be true for any ODBC data source and I am finding that what you have listed only applies *partially*. Even in Access, the dynamic columns that are generated with a PIVOT operator are very difficult to work with, since you cannot bind reports or forms to those column names that are changing
Perhaps you need to take the long expression and make sure that it is converted (via cast() perhaps) to a numeric value? Comment by Harry June 11th, 2013 at 6:14 pm Hello Dave, Your post helped a lot to give me the number of business days between a date range. Comment by Shashi July 31st, 2012 at 1:15 pm Hi Dave, We had a request to exclude only Sunday, I made few change to array it is working absolutely fine
I was modifying an existing query file and when I first tried, MSSQL gave me an error saying that I need to put all the data fields in the select statement in GROUP BY clause. As such, I was hoping to get the following result set: Columns: Year, Period, MonthToDate, YearToDate Row1: 2010, 0, 100, 100 Row2: 2010, 1, 0, 100 Row3: 2010, 2, 0, 100 Row4: 2010, 3, 200, 300 Row5: 2010, 4, 0, 300 Row6: 2010, 5, 0, 300 Row7: 2010, 6, 0, 300 Row8: 2010, 7, 0, 300 Row9: 2010, 8, 0, 300 Row10: 2010, 9, 300, 600 Row11: 2010, 10, 0, 600 Row12: 2010, 11, 0, 600 Row13: 2010, 12, 0, 600 It looks like I would also need some grouping on the script
A Simple Formula to Calculate the ISO Week Number - SQLServerCentral
It also turns out that the first of January, 1900 was a Monday (as is 01 January 1753 if you need to change the calculation to handle dates prior to 1900). Very fortunately for me, I had misplaced my previously written T-SQL solution to solve for ISO Week Numbers and decided to do a quick web search to find one instead of trying to find my own
Why not use the same logic to calculate the difference for the time units in the timestamp values? The reason is that when you get down to the time units, the difference between two timestamps might be higher than an integer can hold. The task is to correctly calculate the differences between the timestamp pairs, considering all possible datetime units, and produce the desired result that Table 2 shows
SQL Server Citation
However, there are times when we need to find out records matching a criteria from all the tables of a SQL Database and today I will explain you a simple way to retrieve those records. So, coming to the point, how do we do Risk Assessment for Database systems, especially SQL Server ? I myself have never come to situation where I have created or used Risk Assessment Register for SQL Server
To completely avoid any possible repurcussions, though, you can simply set the affinity so that each instance has a defined (and ideally different) list to use. Perhaps this was a goof-up or oversight, but in my mind, it is a big gap of missing material (especially since there are material differences between SQL 2008 R2 and pre-R2 such as the discussed maximums)

How many months are there between Dec 27 and Feb 28? How about Dec 28 and Feb 28? Dec 29? What about Dec 15 to Jan 13? Dec 15 to Jan 14? As others have mentioned, DATEDIFF just measures the number of boundaries that have been passed

Using DATEADD and DATEDIFF to calculate SQL Server datetime values
Here are the results generated by the SELECT statement: OrderID OrderDate DelivDate 1002 2008-08-27 13:40:22.357 2008-09-06 13:40:22.357 As expected, the DelivDate value is 10 days later than the OrderDate value.

SQL Server Forums - number of working days between two dates
-- This method is used because the error displays -- the string it was trying to convert, and so the -- calling application sees a formatted error message. I tested with just one date and it worked.I may still have an issue cause I'm trying to find the number of working days from a datefield in a table to a set date
