Context Connection & UsingWhen working with the SQL CLR, should I be using "using" when referring to
the "context connection"? Hello Scott,
According to your description, you want to know if we should wrap the connection with "using" blocks in SQL CLR, correct? If I misunderstood anything here, please don't hesitate to correct me. In my opinion, working with the Using Block is recommended, but no necessary. Working with using block guarantees disposal of the resources, no matter how we exit the block. However, if you make sure you will close the connection by yourself, it is not necessary to put it into Using Block again. Hope this helps. Please feel free to update there again, if there is anything unclear. We are glad to assist you.

Hi Wen,
Thanks for you response. I am aware of what using does and agree that if you manage the connection correctly, its use is not needed. My question is a bit more involved than this though. When using the context connection in SQL CLR, should Using be used (or if I am managing the connection myself, should I be closing and disposing it)? The point being that the context connection represents the connection that that calling code is using. If I were to close and dispose of that connection in the SQL CLR code, then wouldn't that have ramifications on the caller's ability to continue to use the connection if desired? -Scott Show quote "WenYuan Wang [MSFT]" <v-wyw***@online.microsoft.com> wrote in message news:%23tGuwK%23LIHA.7908@TK2MSFTNGHUB02.phx.gbl... > Hello Scott, > > According to your description, you want to know if we should wrap the > connection with "using" blocks in SQL CLR, correct?

It sound like your main concern is if closing/disposing the connection in SQLCLR code will effect on the caller's ability to continue to use the connection, correct? Please don't hesitate to correct me, if I misunderstood anything again. SQL CLR creates new connection with the same context of caller's connection in his code. It doesn't use caller's connection. They are not the same connection. Thereby, (as far as I know), whatever we do on the context connection, this will not effect on the caller's connection. Hope this helps.
