OK to get straight to the point, is it possible to use CLR stored procs from
SQLExpress instance or from an MDF external database file ?
If the answer is "no and no" then there's no need to read on, otherwise
please read on....
I have a very simple stored proc...
[Microsoft.SqlServer.Server.SqlProcedure]
public static void GetCustomer(int customerid)
{
using (SqlConnection connection = new SqlConnection("context
connection=true"))
{
connection.Open();
SqlCommand command = new SqlCommand("Select * from Customer
where CustomerID = " + customerid);
SqlContext.Pipe.ExecuteAndSend(command);
}
}
I have attempted to call this from within a database within SQLExpress and
also from within an MDF external database file with results as follows....
--SQLEXPRESS
CASE----
I've switched on CLR for SQLExpress by going to the SQL Server 2005 Surface
Area Configuration selecting CLR Integration and checking "Enable CLR
integration".
When I attempt to call this stored proc within a database inside my
SQLExpress instance I get...
System.Data.SqlClient.SqlException was caught
Message="A .NET Framework error occurred during execution of user defined
routine or aggregate 'GetCustomer': \r\nSystem.InvalidOperationException:

It's pretty clear I need to switch on CLR integration for my MDF but how ?
--END STANDALONE MDF
CASE----
Has anyone else encountered these problems ?
Do you have a solution ?
Thanks in advance...
MichaelWhen you use User Instance = True, you get a new (virgin) instance of SQL
Server Express. This does not have the CLR enabled which means your
application will have to enable it (at least once).

This fixed the prob with using SQLExpress ... I did have a break point in
the stored proc, I've only just realised it wasn't hitting it for some
reason but thats another issue.
I'm still at a loss though how I enable the CLR for an MDF file.

I did have CLR enabled for SQLExpress. I don't know of anyway to turn it on
for an MDF. I know you can set it in code for SQLExpress using...
EXEC sp_configure 'show advanced options' , '1';
go
reconfigure;
go
EXEC sp_configure 'clr enabled' , '1'
go
reconfigure;
EXEC sp_configure 'show advanced options' , '1';
go
But correct me if I'm mistaken but these system procs rnt available in an
MDF. So does this mean T-SQL only for MDF database's (not hosted by an
instance of SQLServer) ?

You need to enable CLR at the *instance* level, not the database level. If
you are using a user instance as Bill suggested, you'll need to enable it
during initialization of your app. This is because SQL Server Express
creates a new instance from the SQL Express template files each time you
connect with 'User Instance=true'. After connecting:
SqlCommand command = new SqlCommand(
"EXEC sp_configure 'clr enabled', 1 RECONFIGURE",
connection);
command.ExecuteNonQuery();
Hope this helps.

This did work. I must say I find it quite strange this needs to be done in
code, when it's really a one off administrative setting.
I did actually try to call this stored proc from a query window within
VS.NET. It seems whenever I use EXEC from a query window in VS.NET (go to
server explorer, right click a Data Connection select "New Query") I get an
error "The EXEC SQL construct or statement is not supported.". Strangely
enough it does seem to continue on and call the stored proc anyhow, results
do appear for the proc. In the case of sp_configure however it does seem to
have failed... I mistakenly mistook this failure as an indication that
this system proc wasn't actually available within the "User Instance"
database file.
As you might tell I'm new to this, I'm finding that the errors and behavior
of the tools, don't seem to be quite as intuitive as they were with VS
2002/2003...

Orlando). The new feature (User Instances) has a few wrinkles that they're
working out. The fact that you're allowed to do this at all (it's an admin
task) is testament to the way the user instance of SS is created and owned.
The other question you (and everyone) need to ask is do I have a problem
that MUST be solved by a CLR executable. There are few good reasons to use
them... just be aware of these issues before going crazy with the new shiny
feature.
