Comments on: SQL SERVER – Introduction to CLR – Simple Example of CLR Stored Procedure http://blog.sqlauthority.com/2008/10/19/sql-server-introduction-to-clr-simple-example-of-clr-stored-procedure/ Personal Notes of Pinal Dave Fri, 10 Feb 2012 04:35:14 +0000 hourly 1 http://wordpress.com/ By: Dilip http://blog.sqlauthority.com/2008/10/19/sql-server-introduction-to-clr-simple-example-of-clr-stored-procedure/#comment-235922 Thu, 12 Jan 2012 08:42:28 +0000 http://sqlauthority.wordpress.com/?p=1390#comment-235922 Hi…. good article….it helped me alot….but,

i want to use a global variable in the procedure…. how can i do this….?
eg:

public static string strr = “hhhiii”;

[Microsoft.SqlServer.Server.SqlProcedure]
public static void sp_GetHexValue(int number)
{
strr = “hhhhhiiiii”;
SqlContext.Pipe.Send(strr);
}

i’m getting an error while deploying.

” Deploy error SQL01268: .Net SqlClient Data Provider: Msg 6211, Level 16, State 1, Line 1 CREATE ASSEMBLY failed because type ‘StoredProcedures’ in external_access assembly ‘TestSQL_CLR_Project’ has a static field ‘strr’. Attributes of static fields in external_access assemblies must be marked readonly in Visual C#, ReadOnly in Visual Basic, or initonly in Visual C++ and intermediate language.
An error occurred while the batch was being executed.”

so, i tried giving readonly property…. it worked…. but, i’m unable to set the value at runtime.

how can i achieve this ….?

Thanks 4 ur help.

EXEC sp_configure ‘show advanced options’ , ’1′;
reconfigure;

EXEC sp_configure ‘clr enabled’ , ’1′ ;
reconfigure;

EXEC sp_configure ‘show advanced options’ , ’0′;
reconfigure;

How would one get the result into a table? This did not work.

Use [vc]

Create Table #t (date nvarchar (255))
Insert Into #t
Exec dbo.clrsptest

Select * from #t
Drop Table #t

Sorry but here i can’t agree with you. T-SQL is used mostly in stored procedures or functions, which they are stored on the server it’s self. Wright noe i am ‘translating’ a stored procedure from SQL into a CLR function, and after i tested it severl times the results are aprox:
10 s for the SQL
35 s for the CLR

One of the time consuming effect for the CLR is opening/closing the readers, executing commands and all the other things that you must do in order to execute the SQL querys.
But i think CLR are one of the best solutions if you want acces to a database from C#.

I only have the Visual Studio that comes with SQL 2008 R2 and it does not have a Visual C# project type.

Both database is in SQL Server.

I’m wondering why it is so difficult to find an example ( in literature or Internet at large ) of converting a T-SQL procedure which contains an “out” variable into an identicale C# CLR stored procedure. Is there something which prohibits this conversion ? If not, can you provide or cite an example ? Real world T-SQL procedures tend to have out parameters. Thx

Dave (Pinal). Thanks to God for bringing you to earth, you have a perculiar way of making programmers life easy, all over the web, there are lots of bla-bla..bla, but every argument you treat, is always a strait and simplest form to a solution.
Keep up with it. YOU ARE MY OBAMA!

you wrote “Stored Procedures, Functions, Triggers can be coded in CLR. CLR is faster than T-SQL in many cases. CLR is mainly used to accomplish task which are not possible by T-SQL or can use lots of resources.”

now, if i save a stored procedure in sql server management studio, isnt it saved as a clr function? up to now i always knew that stored procedures are “compiled”, but your sentences made me understand as if the sp way is similar to hardcoding the sql query text in code and execute it with a SqlConnection object.

can you clarify this point a little bit more please?

I hope you dont mind me putting reference’s to other blogs

Hi friends
In case you run into the same problem as i did .
i.e. at command prompt if you get
“Execution of user code in the .NET Framework is disabled. Enable “clr enabled” configuration option.”

then you can correct that by
