Didn't work for me. I'll leave the lottery ticket buying to you :-)
( I did a select on the column in question; most came up as NULL, but
one row had 0000-00-00... even after applying the setting to the base
DB)

That won't work for values already inserted in the DB.

That should fix your problem.
some.connectionDictionary = {
URL = "jdbc:mysql://127.0.0.1/somedb?
capitalizeTypeNames=true&autoReconnect=true&maxReconnects=3&zeroDate
TimeBehavior=convertToNull";
....

oh yeah, happens all the time. There are more than a few
strangenesses about dates in Mysql. Make sure to assign your
dates a
value, or else leave them as null. Make sure to create all
timestamp
columns with default null onupdate null. (I think thats the right
syntax, you should check) If you don't, the first date column in
your table will default to current_timestamp, and it will magically
change itself on every update.
To recover from this situation, you'll need to manually fix the
values in the DB.

I'm just starting a new project using mySQL, and am running into
date issues. If I have an attribute that's external type is set to
DATE, and Java type is NSTimestamp, I'm able to insert values, but
when retrieving them I get the following exception.
I remember a few posts that touched on stricter date type issues
with mySQL 5, but can't seem to locate them worth a damned at the
moment;-) Does anybody have a fix or work around for this? Thanks.
