Sweet SQL Lass: "I can't take this database offline!" An anguished cry, which I have heard twice today.
The problem is, if you try to take a database offline, it will not actually complete until the current transaction has ended (or been forcibly killed), as there is a lock on the database. Killing a transaction is a bit untidy. As we find here "The ALTER DATABASE statement waits indefinitely if there is any lock on the database. " One generally ends up with 'Database is in transition...Error 952' when trying to ascertain what the databases is up to, and very little seems to have an effect, including restarting SQL in some cases: and that assumes that restarting SQL is even an option. Fortunately, if one uses a bit of T-SQL, one can persuade the last transaction to rollback neatly, unlocking everything, and reducing hassle. USE master. Simple Example of Cursor.

Using Extended Properties on Database Objects. In using extended properties, you can add text, such as descriptive or instructional content, add input masks, and add formatting rules as properties of objects in a database or of the database itself.
For example, you can add an extended property to a schema, a schema's view, or to a column in the view. Because extended properties are stored in the database, all applications reading the properties can evaluate the object in the same way. This helps enforce consistency in the way data is treated by all the programs in the system.
New Installation (Reporting Services) Reporting Services is a collection of server and client applications used for business reporting.
You can install server components on a single computer or on multiple computers. You can install the client components alongside server components or on separate workstations. To install server components, the computer must satisfy the hardware and software requirements. If the computer is not configured as an application server or if the operating system does not support HTTP.SYS, Reporting Services will not be available in the Components to Install page in the Installation Wizard. Reporting Services is installed through the SQL Server installation media. Parsing - How to strip all non-alphabetic characters from string in SQL Server. Migrate MySQL to Microsoft SQL Server.

In the process, I've tried to make the SQL examples as generic as possible, although you will still have to consult the documentation for your own database system. Graphics no longer require the SVG plugin; large-image and text-only views of each graphic are provided for all readers; the menu is now arranged by topic areas; and the print version (minus left-side navigation) is done automatically by a style sheet.
