Hi list,

I've stumbled on a problem related to this issue. The database is MySQL again and the zero dates are widely used there. What causes my problem is that when an EO is fetched and it had a zero date set for some column, the corresponding property is set to null, so when I edit and try to save the modified object I get an exception because the column that contained the zero date does not allow null. Do you know if there is some work around for this ?

Thanks in advance,
Katya

WOW! that worked!
Thanks a lot!

Hello list.
Is there some known hint to get rid with exception raised when dealing
with zero dates in SQL?
I'm taking data from database maintained with a third party program.

What type of database?

When a date is undefined that program puts "0000-00-00" into database
which is acceptable for SQL but raises an exception in WO.
How can I make EOF treat that value normally returning null for date
in corresponding EnterpriseObject?

If it's MySQL your jdbc connection url should probably have: ....?zeroDateTimeBehavior=convertToNull

with regards,
