And ... I got te same error. The ODBC function SQLSetConnectAttr(SQL_ATTR_TXN_ISOLATION) returns the error. I have conntrol over this - I don't want to set the Isolation-level. I clone the connection and bind the cloned to the second query all works fine. But I don't want to ask myself the whole implementation time, if some query might be in Insert mode and I am allowed to set up some select. In my opinion it must be possible to select some data with a second query while another is in insert mode (and Post/ApllyUpdate the inserted row). What am I doing wrong??? Do I have to install another DB2CLI.dll? Please help me. The problem is very urgent for me.

But i see where the problem lies. We start transaction in the metadata retrieval code ( a workaround done for DB2 V6) and since is a transaction active we cannot set the Transaction Isolation level again on ApplyUpdates() and hence the failure.

One day all works fine and another nothing works. Is it possible to know when fix is available? As I read here, error occures when I make SELECT between INSERT during the same transaction, doesn't it? And is there any workaround to not wait for fix available? Thanx a lot.
