Why am I getting the error "Non-blob column in table required to perform operation" when trying to access a BLOB or CLOB with Oracle 8?
These LOB indexes do not have corresponding column definitions. The error will occur when the primary key has a name that causes it to be sorted after the LOB indexes in the result set.
The error does not occur for users with roles other than DBA, EXP_FULL_DATABASE, IMP_FULL_DATABASE or SELECT_CATALOG_ROLE.
To determine what roles a the current user has query SYS.USER_ROLE_PRIVS.
To determine what roles all users have been granted query SYS.DBA_ROLE_PRIVS when logged in as a user with a GRANTED role of DBA, EXP_FULL_DATABASE, IMP_FULL_DATABASE or SELECT_CATALOG_ROLE.
