Jira issue originally created by user sebak:
I have a a single table inheritance, with a boolean discriminator field, see: http://pastie.org/1269467
As MySQL does not have a boolean field, true / false should be translated to 1/0 (as it uses a TINYINT(1) field instead).
If I use 1 / 0 in the annotation instead of true / false it works, but than it's not boolean anymore...
So it should either translate that, or mention this in the documentation (although vendor specific exceptions should be avoided imo).
Comment created by @beberlei:
This is not supported, i suggest using smallint and 0 / 1 instead.
Throwing an exception now on using boolean, object, array, datetime, date or time for the discriminator column.
Issue was closed with resolution "Fixed"
