If a “ORA-01008 Not All Variables Bound” error is displayed, this could probably be related to oracle bug 5254759.
This could be solved by upgrading to 10.2.04 or installing the interim patch.
However if you need a quick and diry workaround you can try to eneable closing cursor on the dsn:
1) Open the ODBC administrator (control panel -> administrative tools -> ODBC)
2) Choose your DSN and click “Configure”
3) In the application tab, check the “enable closing cursor” checkbox.
It is important to note that this solution may not always work and it will probably result in a notable performance reduction but it may help until the patchset is applied.
