Subject Re: SQL TIMESTAMP and Torque java.util.Date mapping.
Date Thu, 07 Aug 2008 12:30:48 GMT
Hi !

Nope, I tried it before, but it seems that "IS NULL" is different from "=
{ts '00-00....}".
By the way, the deprecated new Date(0, 0, 0, 0, 0, 0) corresponds to "{ts
'1899-12-31 00:00:00.0'}" on my env.
I could also build a custome crit like dateCrit.add(TestPeer.EXPIRES,
(Object)"={ts '0000-00-00 00:00:00.0'}", Criteria.CUSTOM) but I don't think
this is generic enough ... maybe some databases work with another timestamp
format (I use Derby here).

Maybe that is because my schema doesn't NULL the value correctly ? Here is
the column definition :
<column name="expires"
      type="TIMESTAMP"
      required="false" />
And the generated SQL:
expiration TIMESTAMP,

Any idea ?
