Besides the obvious issue of the database going offline for 30 seconds or so (make sure no jobs are running) restarting the service will zero out all of the server counters. The bigger the model database the number of extents available will increase and it will take more time to copy the extents to the new database in 64kb chunks

Enterprise Reporting Engine Reports can easily be delivered throughout the organization, both internally and externally, with simplified deployment and configuration. Large User-Defined Types SQL Server 2008 eliminates the 8-KB limit for User-Defined Types (UDTs), allowing users to dramatically expand the size of their UDTs

Too many of the commercial SQL Server performance tool emphasis generating pretty charts and reports on query execution statistics, thinking that by giving the top SQL to the originating developer is all that is expected of the DBA. The checkpoint IO surge would increase latency on data reads, but the primary reason for the performance drop is the increase (degradation) in log write latency

Querying SQL Server 2012: Part II - CodeProject

8.1 CROSS APPLY The CROSS APPLY operator works like an INNER JOIN in that it can match rows from two tables and leaves out rows that were not matched by the other table in the result. The following query gets the top three most expensive orders regardless of customer and as a result each Person is duplicated three times in the result (once for each order, regardless of whether the order was placed by this Person)

Let's take a look at the query as shown below - --CROSS JOIN SELECT ContactName, CompanyName, City, OrderID, OrderDate, RequiredDate FROM Customers CROSS JOIN Orders Summary In this article, we have seen different types of joins you can perform in SQL Server. The query is as shown below - The output of the above query is as shown below - EXCEPT Operator We will now explore the last operator, the EXCEPT operator

Temporary table should be much smaller that original source table, can be indexed easily (if needed) and can cached subset of data which you are interested in. You can either re-craft your query to remove the order by, add a good clustered index and covering index(es) as previously mentioned, or query the DMV to check for IO pressure to see if hardware related

sql server - Splitting SQL query with many joins into smaller ones helps? - Database Administrators Stack Exchange


  http://dba.stackexchange.com/questions/43616/splitting-sql-query-with-many-joins-into-smaller-ones-helps
The intermediate result tables will now have fresh statistics of their own, thus joining much better compared to the statistics of a deep tree that become skewed early on and end up as Science Fiction soon afterwards. I cannot say there is a standard about using temporary tables when number of joins is greater than some fixed number, but it's definitely an option which can improve performance

  http://blog.sqlauthority.com/2008/04/22/sql-server-better-performance-left-join-or-not-in/
I was joining between a daily transaction table with 30 million rows and a master table to check if there are any entries.IN operator took quite a long time to execute , but left join ran in just 2 mins. Also, when you look at the statistics output you can see that the Join query is doing much better than the Not In query based on reads and scans, which in a high volume environment will be a much better indication of performance anyway

Thus, the optimizer sniffs the values, uses statistics, computes the correct cardinality estimation and produces an optimized plan, which in our case is different. Now, if you know (from the past usage of the table) that most of the times users punch in a SalesPersonID that produces a Nested Loop plan, you can use OPTIMIZE FOR hint
