+I tried to investigate on this a little more. I'm getting now the
+following stack trace on Linux:
+
+Unhandled Exception: System.NullReferenceException: Object reference
+not set to an instance of an object
+in <0x00000> <unknown method>
+in (wrapper managed-to-native) System.Data.Odbc.libodbc:SQLExecute

+
+It hangs in the ExecSQL-Method:
+
+private void ExecSQL(string sql)
+{
+   OdbcReturn ret;
+
+   if ((Parameters.Count>0) && !prepared)
+     Prepare();
+        
+   if (prepared)
+   {
+     ret=libodbc.SQLExecute(hstmt);
+     // .. snip ..
+
+The call of libodbc.SQLExecute fails.
+Is somebody already investigating on this? If not, where can I find
+more info about libodbc-call, so that I can do it myself?
+
+Any hints would be really appreciated, because this for me is
+(hopefully) the last hurdle before deploying on Linux/Mono instead of
+using Win/MS.NET
