View vs. Table Valued Function vs. Multi-Statement Table Valued Function - Home Of The Scary DBA
Oh, and if you check the execution plans, note that the multi-statement UDF is marked as the least costly even though it actually performs twice as slow as the others. With the primary key in place, I find these functions to be significantly faster than views or table-valued functions, especially as the data set grows larger
SQL Server T-SQL Tuning -TVF and Scalar Functions - SQL Server Performance
Assuming this is an attribute of Eployees, the whole join to Departments is not needed in the first example!!! It also is an odd function feeding an employee ID and returning aggregates over all emplyees in the same department. A short note on iTVF, you just return the type TABLE, and then jist as with a view, make the body up with a single select statement (which now can use the parameters given to the iTVF, contrarary to a regular view)
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
The Case for Scalar-valued, User-defined Functions in T-SQL - SQLServerCentral
ElapsedMSiTVF 6676 ElapsedMSsUDF 7436 This demonstrates not only that the iTVF version of our running totals function is faster, but also the correct way to calculate timing results for a sUDF (as noted again by Jeff Moden in the article I mentioned in the second paragraph)
Unfortunately though, when you invoke a scalar UDF as part of a query, and pass the function a column from the table as input, the function is invoked separately for each row. This is how SQL Server always handled scalar UDFs from the moment those were introduced in the product (version 2000) and still does today (version 2008)
Multi-statement Table Valued Functions 2 Replies One of the biggest challenges for the developers who are not familiar with T-SQL is understanding the conceptual difference between client side and T-SQL functions. Source code has been updated to include the last example This entry was posted in SQL Server 2005, SQL Server 2008, T-SQL on October 23, 2011 by Dmitri Korotkevitch
To obtain the remote @@IDENTITY value, execute a stored procedure in the context of the remote server, assigning the @@IDENTITY value to an output parameter. When we insert a new row into Fruit, two IDENTITY values will be produced: one for the Fruit table and one for the FruitAudit table, which was modified by the trigger
Your code examples actually work! Thanks for your hard work! M Ayub This is excellent as usual man I love the way you explain things in such a simple way. The string containing words or letters separated (delimited) by comma will be split into Table values.He has also explained how to use the Split function to split a string in a SQL Query or Stored Procedures in SQL Server 2005, 2008 and 2012 versions

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)
sql server - T SQL Table Valued Function to Split a Column on commas - Database Administrators Stack Exchange
This is getting really disheartening especially since there are no built in split functions on MSSQL server (WHY WHY WHY?!) and all the similar functions I've found on the web are absolute trash or simply irrelevant to what I'm trying to do. This will almost certainly outperform any of the solutions above, especially if you are building a comma-separated string in your app specifically so that your stored procedure can call a TVP to split it apart again
now i checked the checbox the values are stored in database table like this 1,2,3.then i want the checked box are disabled after value stored tothe particular ids what to do ???? helpme...
permissions - Workaround for calling table-valued function remotely in SQL Server has even more issues - Stack Overflow
I'm not sure why I'm getting this error, because the mapping exists for my username, and if I simply replace the table-valued function with an actual table, it returns the results fine. Unfortunately, the call fails on the linked server with the error: Msg 4122, Level 16, State 1, Line 29 Remote table-valued function calls are not allowed
This way we can get the original table back if aggregate functions was not applied on the data or data was in such form that aggregate function might have not made any difference.

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 Table Valued Parameters - CodeProject
First, create the table given below: CREATE TABLE FileDetails( FileName varchar(50) PRIMARY KEY, CreatedDate varchar(50) , Size decimal(18, 0) ) Then, we should declare a new table User Defined Type in the database: create type FileDetailsType as table ( FileName varchar(50), CreatedDate varchar(50), Size decimal(18,0) ) Then, create a Stored Procedure that gets a parameter of the above type, and insert several rows in a single command. And, last night, I found out that SQL Server now supports table valued parameters which allow us to send data tables as parameters to Stored Procedures
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
In earlier versions of SQL SERVER it is not possible to pass a table variable in stored procedure as a parameter, but now in SQL SERVER 2008 we can use Table-Valued Parameter to send multiple rows of data to a stored procedure or a function without creating a temporary table or passing so many parameters. Is there any thing similar to this, that can be used from Application layer side in java language with SQL Server 2008? This is very urgent requirement, can some one help? Thanks, Swetha
