Whenever I try to query aa table with a xmltype column, without using a substr() call, I get this error:
"Access violation at address 00000000195EE600 in module 'OraOCIEI11.dll'. Read of address 0000000000000010"
Connect using a 10g or 9i Oracle client. The issue only occurs using an 11g Oracle client.
Waiting for fix to be included in a future version of Toad for Oracle.
