Hello, sorry but i have found the error. strange but it's work
the error occur cause of i set fetch all to false. when the query run in the server, the component access with the other connection that is not connection that establish with tMSConnection. i do not know how it;s happened but when i set it to true the problem solved. may be it's a bug or maybe this is the SDAC behavior...
if you understand the SDAC source please explain this problem thx
