[Firebird-devel] "Column has been unexpectedly deleted" but only on SS and SC

[Jiri C. <di...@ci...>]

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?
