In CLR fuction i had written a code

string MachineName = System.Environment.MachineName.ToString();

Can any one suggest me why this is happing

You can copy DLL file from VS project BIN folder, and register this DLL asembly on SQL Server using SQL commands. Example:

create ASSEMBLY SQLCLRTest1 from ‘c:\temp\SQLCLRTest1.dll’ WITH PERMISSION_SET = SAFE
go

create procedure YOURCLRPROCEDURENAME(@YOYRPARAMETERNAME int)
as
external name
[SQLCLRTest1].[StoredProcedures].[YOURC#PROCEDURENAME]
go

After that you can delete DLL file from SQL Server. Regards.

Thanks for detail help on Extended stored procedure, I have a query related to build. My client does not allowed me to install visual studio on production environment so there is any option to generate DLL on local PC with Local database and implement at production server.

Pl. help me on this issue.

my user has sysadmin right
but i am not dbowner of database
i change sp_changedbowner to my user and deploy that and then re change to original one.
Assembly is UNSAFE, database is Trustworthy on and clr is on

but execution with dbowner user stored procedure gives below error
dbowner is not sysadmin.

Msg 10314, Level 16, State 11, Line 4
An error occurred in the Microsoft .NET Framework while trying to load assembly id 65672. The server may be running out of resources, or the assembly may not be trusted with PERMISSION_SET = EXTERNAL_ACCESS or UNSAFE. Run the query again, or check documentation to see how to solve the assembly trust issues. For more information about this error:

if i change that dbowner and gives right to sysadmin then it works.
but that’s not what i am looking for.

i tried to set permission on database that execure, create assembly and alter any assembly but error continues.

Can you let me know which right need to assign when it’s not sysadmin
I already checked MSDN and other blogs but not get good idea for practical situations.

i create stored procedure with EXECUTE AS CALLER.

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;

Use [vc]

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

Select * from #t
Drop Table #t

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#.

thank you very much

How can I connect to two or more databases using this project ?
