Therefore, the easiest way to partition an existing table is to create a partitioned clustered index on the table, although, it might not be the most efficient way doing so. And you cannot simply drop the UNIQUE constraint or disable the pertaining index while performing the switch, as long as there are FILESTREAM data in the table

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
When assigning from a query that returns more than one value, SELECT will assign the last value returned by the query and hide the fact that the query returned more than one row. SELECT When Assigning Variables There are 2 ways of assigning a value to a local variable previously created with the DECLARE @LocalVariable statement, namely using the SET and the SELECT statements
The following example shows an invalid use of the AS keyword with a table variable: DECLARE @mytable AS table ( col1 int NOT NULL ) You must remove the AS keyword to make this code valid: DECLARE @mytable table ( col1 int NOT NULL ) T-SQL supports only local variables. SQL Server usually drops the table when the connection that created the table disconnects and the reference counter becomes 0, meaning that no user is using the table

database - How would you implement sequences in Microsoft SQL Server? - Stack Overflow
I'd like to comment the statement in the original question: "Besides, inserting a row and then asking the DB what the number just seems so hackish." Well, there is not much we can do about it here. I'm assuming that your relational model is based on artificial keys, and in this context, I'll offer the following observation: We should never seek to imbue artificial keys with meaning; their only purpose should be to link related records

This particular workshop will not make you an SSIS developer, for that you need longer training and some experience, but it will definitely get you started in the right direction. about three weeks ago, this time with a workshop based in Analysis Services 2008, after the positive experience with their previous session, I could not miss this one
Differences between SET and SELECT in SQL Server : Narayana Vyas Kondreddi's home page
At the end of the test, the script displays how much time (in Seconds) it took to assign values to variables using SET, SELECT and SELECT with multiple assignments. Based on the above results, when using a query to populate variables, I suggest you always use SET, if you want to be sure that only one row is returned
sql - SET versus SELECT when assigning variables? - Stack Overflow
SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT.

Variables and assignments in an UPDATE statement Script for shrinking transaction logs on server SQL XML Bulk Load and Namespaces COUNT on LEFT JOIN The select list for the INSERT statement contains fewer items than the insert list. Having to do this in an update query which could number the thousands of records, it presented the problem of how to get the calculating logic into the update query without having to resort to cursors and without having to call the calculating function too many times for each row
Database Discussion Boards - CodeProject
Depending on your budget splashing out an a decent SAN solution may help - although SAN technology is beyond my current level of experience, I am just someone who uses it while other people configure it. I think many people still forget that computers have moving parts, they are machines - they are not some sort of quantum flux probability engine that returns results at the speed of light
Geeks With Blogs
I expected it to be similar to the cursor method, as both involve a single scan of the source table, and both calculate the running total once only for each row in the table. The key for the cursor method is to ensure the data you are "cursoring" through is in the correct order, as the query optimzier does not understand cursors

Finally, all remaining log entries for all servers combined are emailed in an easy-to-read tabular layout: Setup in more detail Below, setup is described for a multi-server situation. It can do this for a number of SQL servers and will check older versions of the server log if the current version contains less than 24 hours of messages (this can happen when SQL is restarted or the log is reinitialized)
My doubt is: How to set environment variables using stored procedures.i did not know how to get those env var values ti t-sql.So,please give me an example to do this.It may be useful for beginners like me.. when I select the data I get is like this 1 2232 eq233 1000 12-12-2011 11:11 39 9.2 text text I want this output to have comma instead of space like 1, 2232, eq233, 1000, 12-12-2011 11:11, 39, 9.2, text text, can some please help

Revealing something that is very tightly related to the physical representation of the data, as opposed to the logical layer that should be exposed to the user. Besides assuring the order of assignment of IDENTITY values, SQL Server 2005 gives you several T-SQL enhancements that make your life much easier and let you develop faster, more flexible solutions that are guaranteed to work correctly

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

SELECT *, NULLIF(Product, NULL) FROM SalesHistory Operations on NULL values Since NULL values are unknown, operations on them typically require some extra processing. The COALESCE function is very useful in a join operation or in queries where you are comparing a single value from a list of possible fields to a single value

SQL Server - Lesson 04: Variables and Data Types
In the real world, when a number is (very) long and becomes difficult to read, such as 79435794, you are allowed to type a symbol called the thousand separator in each thousand increment. It follows the same rules and principles as the datetime data type except that a date value must be comprised between January 1st, 1900 and June 6, 2079

MySQL :: MySQL 5.0 Reference Manual :: 13.2.8 SELECT Syntax
If you use FOR UPDATE with a storage engine that uses page or row locks, rows examined by the query are write-locked until the end of the current transaction. For example, in the following statement, columnb is treated as an alias name: SELECT columna columnb FROM mytable; For this reason, it is good practice to be in the habit of using AS explicitly when specifying column aliases
