When running SELECT * FROM DBA_HIST_SQLBIND, an Access Violation error is given. More specifically it looks like an issue with the VALUE_ANYDATA column. If selecting any other column except this value_anydata there is no error.
There is no error when reviewing the object in schema browser and it's data grid. But in desc or schema browser, this column does not get displayed.
Toad not able to handle the Oracle ANYDATA datatype.
Do not query for a column of type ANYDATA. There should be no problems with a result set that does not include this datatype.
Issue fixed in version 10.0. The latest version of Toad for Oracle can be downloaded here.
