Is it possible to create thread & start from CLR Stored Proc

My simple CLR Stored procedure is as below:

[Microsoft.SqlServer.Server.SqlProcedure]
public static int MyParallelStoredProc(string name1, string name2)
{
Thread t = null;
Worker wth = null;
int parallel = 2;
Object[] obj = new object [parallel];
SqlPipe p;
p = SqlContext.Pipe;

for (int i = 0; i < parallel; i++)
{
if (i == 0)
wth = new Worker(name1);
else
wth = new Worker(name2);
t = new Thread(new System.Threading.ThreadStart(wth.WorkerProc));
t.Name = "Thread -" + i.ToString() + ":";
t.Start();
p.Send(t.Name + ":Started");
obj[ i] = t;
}
for (int i = 0; i < parallel; i++)
{
t = (System.Threading.Thread)obj[ i];
t.Join();
p.Send(t.Name + ":Finished");
}
return 0;
}

The worker class implementing Thread Proc:

public class Worker
{
private string Name;

public Worker(string name)
{
SqlPipe p;
p = SqlContext.Pipe;
Name = name;
p.Send("In Constructor:" + Name);
}

public void WorkerProc()
{
SqlPipe p;
p = SqlContext.Pipe;
for (int i = 0; i < 10; i++)
p.Send(i.ToString()+":"+Name);
}
}

The assembly is registered with UNSAFE permission set.

CREATE ASSEMBLY
ThreadTest
FROM
'C:\\ThreadTest\bin\Debug\ThreadTest.dll'
WITH
permission_set = unsafe;
GO

CREATE PROC ParallelStoredProc
@.Name1 NVARCHAR(1024),
@.Name2 NVARCHAR(1024)
AS
EXTERNAL NAME ThreadTest.[MyTest.ThreadTest].MyParallelStoredProc

When I invoke the the stored procedure from T-SQL script as below,

EXEC ParallelStoredProc @.Name1, @.Name2

the thread class constructor gets called; but the 'WorkerProc' does not execute ?

Whether an UNSAFE assembly is allowed to spawn threads

inside SQL Server ?

Your code works correctly to start and run threads under unsafe. The reason you think it doesn't work is because the SqlContext connection is not available on new threads, so you can't use it to Pipe.Send information back.

If you try/catch for exceptions in your WorkerProc, you should see an error like the following:

"The requested operation requires a Sql Server execution thread. The current thread was started by user code or other non-Sql Server engine code."

Thanks steve. Your input was very useful.

If I use SqlConnection in WorkerProc, the thread gets aborted

and goes into "Stopped" state.

It means the main CLR Stored proc can only execute the T-SQL commands ?

WorkerProc's are restricted to computations.

Is it possible to call an Oracle stored procedure and pass parameters to them from reporti

I've set up a shared datasource to oracle with the option of prompting for
credientals. The report works with just static SQL in the Query designer. I
have been trying for a number of days now to use a call to an oracle stored
procedure or function as my report data set without success.
The function called sp_ListEmp has one parameter of type number. To call the
function I have tried adding {call sp_ListEmp(?)} into the Query designer
and setting the command type to Text. I have added the parameter ? and made
that equal to a Report parameter EMPNO of Integer type that I have added to
the report. So I have in the parameter tab of the Dataset
?=Parameters!EMPNO.Value. I recieve the following error message 'An error
occurred while executing the query. ORA-01036: illegal variable
name/number.'
For the stored procedure curspkg_join.open_join_cursor1 I have not even been
able to call the procedure with recieving an error for the second parameter
which is of type refcursor. Does anyone know if it is possible to call
Oracle stored procedures and pass parameters to them from reporting
services?
I have added the code for the stored procedure and function and also the
tables for which I have been working on below and also the commands I use in
SQL Plus to prove that the actual function and stored procedure work. This
is causing me much woe.

Also make sure you use the managed Oracle provider (i.e. "Oracle" in the
data source dialog) and not OleDB.

I'm still unsure of the syntax that I should use in Reporting Services when
calling the sp. Where/how do I reference the out ref cursor? Example I call
the procedure using -
{ call test_package.get_customers(?, ) }
I get the following error 'The data extension Oracle does not support
unnamed parameters. Use named parameters instead.'
So my question is how do I reference the out ref cursor in Reporting
services?

Regarding the OUT cursor - don't reference it, just omit that parameter.
A better practice for stored procedures is to set the command type of the
query to StoredProcedure instead of Text. In that case, the query text is
just the name of the stored procedure "test_package.get_customers". The
parameters will automatically be determined by report designer on clicking
on the refresh fields icon.
