Hi, I'm now working on DNET-359. On SS everything is fine, but on CS/SC the error happens.
To be precise the order of events is: Select 1 Select 1 success Alter Alter success Select 2 Select 2 error: Datatype <dtype_unknown> is not supported for sorting operation Insert Insert error: Column has been unexpectedly deleted In fact you don't have to do it in threads and fiddle with pooling. If you do (sequentially): Connection 1: Open Connection 2: Open Connection 2: Select Connection 1: Alter Connection 2: Select Connection 2: Insert you'll get same result. Is this something that is expected? Can I, from provider's side, do something better to avoid it? -- Jiri {x2} Cincura (x2develop.com founder) http://blog.cincura.net/ | http://www.ID3renamer.com ------------------------------------------------------------------------------ Precog is a next-generation analytics platform capable of advanced analytics on semi-structured data.
