Just to confirm it, I checked sys catalogs, also compared these entries with logs generated after the same operations on temp tables, and I am convinced they are the logs on table variables

SQL Server (2008): Passing Table Parameter to Stored Procedure - Database Tutorials - Codecall
With SQL Server 2008 (and above), you can pass table variables to stored procedures and user defined functions and have them handle those tables without problem. CREATE TYPE NewMemberTable AS TABLE ( UsrName nvarchar(50) PRIMARY KEY , FullName nvarchar(50) NOT NULL , EmailAddy nvarchar(254) NOT NULL ); Execute that command and you will get a new data type named NewMemberTable
This may also answer Alun's question "I understand you need a 'select' however to get the field names you would need to do some form of call before hand else when you get the 'returned' table how are you going to process it?" Under our front-end configuration management, there will ALWAYS be certain fields which will NEVER be deleted or modified (ie, SystemID, SystemName, FunctionID, FunctionName). I am a contractor on the customer's site - everything belongs to them! I need to create a view, function, or something, from which I can perform a SELECT against
(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

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 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
Basically, a table-valued parameter lets you use an array of data in T-SQL, as well as send an entire data-set table as a parameter in a stored procedure or function. If the number of values being populated in the .NET data table are very high (tens of thousands in our case), it degrades performance of the server due to high number of complilation and possibly plan cache bloating too

2) Using a DataReader you can loop thru the order records and store them in a local data structure (collection) and then call the DataReader's NextResult method (or is it NextRecordset?) to read the detail records from the same data reader. Check out these results below: Test Project (1000 Iterations) - T-SQL 17 min 20 sec 765 ms - CLR 0 min 3 sec 453 ms As you can see, the difference is drastic

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
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
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
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
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)
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 - 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
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
