John Scoles of the Pythian group dropped me a line to say he'd released a new version of Perl's DBD::Oracle driver on Friday. He says:
innovative features in the last few releases namely it now supports
1) Seamless Support for SELECT of Embedded objects (VARRY,TABLE,OBJECT)
fields
2) Support for insert of XML documents into XMLType fields
3) Support scrollable cursors
4) Support for INOUT array Binding
5) Support for the 10.2 Data Interface for Persistent LOBs
