Answer 1

Unfortunately this will not work.
for:

update episodes set `ending` = NULL 
WHERE `ending` = '0000-00-00'

If 0000-00-00 is in the where clause, you get the error:

"1292 - Incorrect datetime value: '0000-00-00' for column 'ending' at row 1".

even if ending has NULL and defalut=null in field definition.
