Hello Experts,

I have created one DLL in .NET which has only one function in it which sends email with SMTP. Function name is SendMail which accepts parameters like to, from, subject, SMTP servername, UserName and other.

Now if i register that DLL on my SQL server then can i call that SendMail function from my T-SQL code and pass those parameters values from Query it self?

I know its possible but how to achieve that i do not know. So, please Experts do the needfull.

Thanks in Advance and Regards.

I assume this is SQL Server 2005?  If so, you can register a .net assembly with CREATE ASSEMBLY.  However, I wonder why you would not just use database mail for this?

If this is SQL Server 2000, you will need to create your dll as an extended stored procedure, which must be written in C++.  No .NET CLR in SQL Server 2000.

Sorry for not being specific.

Its not SQL Server 2005. We are running on SQL server 2000 with SP4.

And if i am not wrong then we can call any function of registered DLL within our SQL. I just forgot the steps how to do that.

We can just pass the name of the DLL and name of the function and then Argument list but excat procedure i forgot.

Please help....

If it's a COM dll you can use sp_oaCreateObjec (something close to that anyway).  But it is not recommended as your dll code runs in-process with sqlserver.exe in that case.
