I found this:
I didn't try debugging, this was happening in QV 10 and Oracle client: SQL*Plus: Release 188.8.131.52.0 Production on Wed Mar 16 12:45:42 2011.
I installed QV9 and it started working.
Note: When I run reload on QV9 it asks for user name and password for ODBC connect and it does reload. But in case QV 10 it did never ask for any user name and pwd for ODBC connection.
But I can not return to QV 9. Anybody can help me?
Look at the picture Please.
