The driver tries to convert it to a date! value, but it's an invalid date for
REBOL :
>> 0000-00-00
** Syntax Error: Invalid date -- 0000-00-00
** Near: (line 1) 0000-00-00

No need to hack ;-), here's a workaround :
- Just after opening the port, add this line :
change-type-handler your-db-port 'date [to string!]
- Now, for this db port only, all MySQL date types will remain as string! (It's
then up to you to decide if and how you want to convert these values)
- You can also provide a little more sophisticate handler for 'date :
to-date-except-zero: func [value][
attempt [value: to date! value]
value
]
change-type-handler your-db-port 'date [to-date-except-zero]
(This one will convert to date! only if possible)
