Passing columns to CLR function

Hello,

I am trying to send to colums to SQL CLR function and get some results. I want the CLR code be like:

Code Snippet

public void DoSomething(SqlDouble[] a, SqlDouble[] b, out SqlDouble x, out SqlDouble y, out SqlDouble z)

{

//Do Something...

x = ....

y=...

z=...

}

I want to call this code from SQL code:

Code Snippet

create table #Temp (float a,float b)

declare @.x float

declare @.y float

declare @.z float

exec dbo.DoSomething(a,b,@.x,@.y,@.z) ?

Do someone have an idea?

Hi Shlomi,

There are many tutorials for achieving this on the net and even in BOL. Look for "CLR User-Defined Functions" Books Online for examples.

In short: If you're using Visual Studio, you open the right project and choose Add Function. Sceleton code is presented and you add your code. Now build the Assembly. After building, go to SQL Server and user CREATE ASSEMBY to import the assembly into SQL Server and last use CREATE FUNCTION to import the function from the assembly. Now you can use your function in SQL Server like you want to.

Pass XML between SPROCs possible in SQL 2000? 2005? (Cross Post - Sorry)

Note: Sorry for cross posting this question with
microsoft.public.sqlserver.programming, but I actually only intended to post
this question here...
A: I can create an XML fragment using the For XML Auto clause. No problem
so far.
B: I have a stored procedure that takes an XML document as ntext and uses
the extended sproc sp_xml_preparedocument and the OPENXML function to create
a table from it - no problem with that.
Now I want to execute my stored procedure using the XML result of part A as
the parameter for the sproc in part B. Is that possible? The only way I
know how to do it right now is to return the result of A using ADO.NET,
insert a root element (to make the XML valid), and then call the sproc
created in part B with this xml as the parameter.Hi Dave,
Welcome to MSDN newsgroup.
Regarding on this issue, I've also noticed your another duplicated thread

One community member Kent have posted some good suggestion there. Please
have a look and feel free to post in that thread...

In SQL Server 2000, FOR XML goes always back to the client only, so using
ADO/OLEDB/ADO.Net in between is necessary...
