Hi Ries,

In fact, I found that the SQL parser relies on a deprecated modifier 
"TYPE" after the CREATE TABLE. It is deprecated since MySQL 4.1 as I 
found. I modified the parser to accept both TYPE and ENGINE (this latest 
is used in fact by ext_tables.sql from core):

-				if ($this->nextPart($parseString, '^(TYPE[[:space:]]*=)'))	{
+				if ($this->nextPart($parseString, '^((ENGINE|TYPE)[[:space:]]*=)'))	{
  					$result['tableType'] = $parseString;
  					$parseString = '';

This way it now works for Oracle. I don't understand why it did not 
crash for MySQL but, anyway... ;-)

I still have a problem with table sys_refindex. I'll debug this too, 
then I'll drop all tables and restart the whole process to see whether 
it works better.

The idea is then to send a patch to core.
