Introduction to Transact SQL User-Defined Functions
For example, if you wished to find authors in the Pubs database who sold no books in a particular state, you could create a couple of functions that would generate the desired resultset. You should exercise caution when implementing functions in your queries and perform benchmarking tests to insure that the benefits of using your functions exceed the performance costs of using them

Using Table-Valued Functions in SQL Server - CodeProject
At my spare time (what ever that actually means) I'm also teaching and consulting on different areas of database management, development and database oriented software design. When Creating a Table Valued Function in Management Studio The easiest way to start creating a table valued function (well, actually any function or procedure) is to use SQL Server Management Studio and start creating an anonymous T-SQL block
There are tons of benefits, and there can be nothing better than the list provided by MSDN: Do not acquire locks for the initial population of data from a client Provide a simple programming model Enable you to include complex business logic in a single routine Reduce round trips to the server Can have a table structure of different cardinality Are strongly typed Enable the client to specify sort order and unique keys Do you use user defined table data types? If yes, how do you find this feature? Do let us know! Until we meet next time, Be courteous. You can use table-valued parameters to send multiple rows of data to a Transact-SQL statement or a routine, such as a stored procedure or function, without creating a temporary table or many parameters
If you receive error messages while trying to query the function, first try restarting the SQL instance to ensure all of the assemblies are loaded properly. This tutorial is a sample of how to create a custom .NET CLR Database project for SQL Server and return SharePoint data from the function to utilize in a SQL query
Creating a user-defined function from the Course SQL Server: Triggers, Stored Procedures, and Functions
Continue to classic layout Stay on new layout Mark video as unwatched Mark all as unwatched Exercise files Access exercise files from a button right under the course name. Topics include: Comparing triggers, functions, and stored procedures Installing and configuring SQL Server Creating a stored procedure Returning data using data sets Creating user-defined functions Using "after," "instead," and nested triggers Modifying existing stored procedures Implementing logging on DELETE Choosing between T-SQL and CLR Executing a stored procedure Passing parameters Subjects: Business Developer IT Software: SQL Server Author: Martin Guidry Creating a user-defined function Now I'd like to talk a little bit about functions, sometimes called user-defined functions in SQL Server 2012
(In case you are thinking that XML or delimited strings could be an alternative here, permit me to point out that they, too, represent intermediate storage. One is the push model, where you create a rowset with the metadata, fill the rowset with your data, and in the regular parameter area, you pass the rowset pointer

SQL Server 2008 T-SQL Enhancements Part - II - SQLServerCentral
He had to write his own logic to bundle all the insert statements into either delimited strings or XML type (OPENXML in SQL Server 2000) and then pass those text values to a procedure or statement. Example In this example we will see how we can create a user-defined table type, create a variable of this type, insert records to it and pass it to a stored procedure as table-valued parameter
While a VB.Net developer recently informed me that there is a SQLBulkCopy object available in .Net to send multiple rows of data to SQL Server at once, the data still can not be passed to a stored proc.Possibly the most anticipated T-SQL feature of SQL Server 2008 is the new Table-Valued Parameters. When multiple rows of data to SQL Server need to send multiple rows of data to SQL Server, developers either had to send one row at a time or come up with other workarounds to meet requirements

SQL Server 2008 User Defined Table Types and Table-Valued Parameters - CodeProject
The simple solution to this is to format an SQL statement with the provided values and execute it; this is a problematic technique (I won't list the reasons). had he taught programming "We learn more from our mistakes than we do from getting it right the first time." My first rule of debugging: "If you get a different error message, you're making progress." My golden rule of database management: "Do not unto others' databases as you would not have done unto yours." My general rule of software development: "Design should be top-down, but implementation should be bottom-up." You may also be interested in..
sql server - Can T-SQL function return user-defined table type? - Stack Overflow
It doesn't mention anything that they could be used to be returned from a user-defined function, unfortunately - so I guess you're right - it's not possible (at least not now)
To get a full function of TRIM you should have another function that able to eliminate all extra spaces in the middle of the string become single space.

tsql - SQL Server 2008 - How do i return a User-Defined Table Type from a Table-Valued Function? - Stack Overflow
And the following from msdn: Restrictions Table-valued parameters have the following restrictions: SQL Server does not maintain statistics on columns of table-valued parameters. Does anyone have any idea if it's possible to return a user defined table type from a table valued function? If not, is there a better workaround other than what i have done? (re-declare the type again)
