Hi Kieran,
2007/4/23, Kieran Kelleher <email@hidden>:
If you have control over the DB design, then don't waste your time
fiddling with ints for booleans. Use the database vendor independent
boolean prototype that uses the strings 'true' and 'false' in the db
and converts on the fly in and out of the DB to Boolean objects.
are you sure is not possible to use as external value "BOOLEAN", without using a custom internal data type?
For details, see the boolean prototype in Wonder's ERPrototypes (just
download it and open the EOModel to see it).
And if you are not using prototypes, you are working too hard. Also
boolean proto is well documented somewhere in Practical WebObjects
book IIRC.
