As an architect first and foremost, I have always been interested in the performance and usage information I can extract out of my SQL Server instances. In versions prior to SQL Server 2005, there was a wide range of ways to get this information, such as cryptic DBCC commands, bit flags in system tables (mostly undocumented), and system stored procedures (some unsupported). SQL Server 2005 introduced us to a new way to derive this data: Dynamic Management Views (DMVs) and Dynamic Management Functions (DMFs), collectively known as DMVs. DMVs brought about a more consistent way to obtain the existing information we were used to retrieving. They also introduced new data that we had never had access to before, or could only access via auditing, extensive tracing, or memory dumps. Consistency is important, as we finally have a relatively stable set of conventions for how the DMVs and DMFs are named, present common data types and column names, and exist in the sys schema. Another aspect about DMVs that I appreciate significantly over system stored procedures and DBCC commands is that I can query against them directly, making it easy to pull only the columns and rows that I want. As an example, in the past, if I only wanted to see sessions that were blocking or being blocked, I would have to create a temporary table up front, insert the results of sp_who2, and run filtered queries against the temporary table (or squint at the whole result set, scrolling up and down).

In this example, you write a script that checks the hour of the day, assigns an appropriate greeting ( Good morning! , Good afternoon! , or Good evening! , depending on the time) to the variable myGreeting, and then displays myGreeting in a dialog box You ll meet dialog boxes in detail in the next chapter, but in this example, you ll use the display dialog command in its simplest form Follow these steps to create the script:

Pulse code modulation, such as is shown at Fig 25-8D, is one form of analog-to-digital (A/D) conversion A voice signal, or any continuously variable signal, can be digitized, or converted into a train of pulses whose amplitudes can achieve only certain defined levels

You should note a couple of important things about DMVs. First, they only contain data since the last time the instance was started. All metrics are literally thrown away when the SQL Server service is shut down. You can make this data persist between restarts, but that is out of scope for this topic (Paul Randal discusses the idea of persisting DMV data across SQL Server restarts at http://www.sqlskills.com/BLOGS/PAUL/ post/Indexes-From-Every-Angle-How-can-you-tell-if-an-index-is-being-used.aspx, and there is also the DMVStats CodePlex project from Tom Davidson and Sanjay Mishra, available at http://www.codeplex.com/sqldmvstats/). Because they also require VIEW SERVER STATE or VIEW DATABASE STATE permissions, depending on the DMV, it is not always possible to have access to the complete set of information that is available. I feel that a couple of things are missing. For example, there is no DMV coverage whatsoever of SQL Server Agent, which has a crude API. This makes it tedious to cull information about jobs and schedules. And there is no way to extend the DMVs by creating my own custom views this was one of my initial questions when the first beta version of SQL Server 2005 arrived in my mailbox. It is also impossible to distinguish, by name alone, between DMVs and DMFs. When using SQL Server Management Studio in SQL Server 2008, and against a SQL Server 2008 instance, IntelliSense will help out a little bit here. The AutoComplete list uses an icon to indicate whether it is a view or a function. Without this hint, I have often queried a DMF without any parameters:

1 In AppleScript Editor, press z-N or choose File | New to create a new script 2 Type the following statement that assigns the hours property of the current date class

SELECT * FROM sys.dm_exec_sql_text;

Resolution In A/D conversion, the number of states is always a power of 2, so that it can be represented as a binary-number code Fidelity improves as the exponent increases The number of states is called the

That results in this error:

to the variable myHour:

Msg 216, Level 16, State 1, Line 1 Parameters were not supplied for the function 'sys.dm_exec_sql_text'.
