Access Violation during query on table ALL_TAB_COLUMNS ( Oracle8i )

Post by redhair » Thu 22 Jan 2015 16:31

Hi ODAC Support Team,

My installed components:
- ODAC 9.4.14 for RAD Studio XE7
- C++ Builder XE 7 with Update 1
- Oracle 8i ( 8.1.7.4.0 ) Enterprise Edition
- Simple project: 1 OraSession ,1 OraQuery --> Direct Mode
( Installed Oracle Client : 11.0.2 64 bit Admin )
- Query :

Code: Select all

SELECT * FROM ALL_TAB_COLUMNS
If i try to query the table ALL_TAB_COLUMNS on a Oracle8i - database, i get an access violation "c0000005 ACCESS VIOLATION".
On other Oracle database versions ( 10g,11g,12c ) all works fine.

The problem only occurs, if i include the column DATA_DEFAULT (LONG-Datatype) in the query.

Code: Select all

SELECT DEFAULT_LENGTH,DATA_DEFAULT FROM ALL_TAB_COLUMNS
Thank you
