Fixing Hibernate, DB2, H2, and Boolean Issues With a User Type
Edit: It was pointed out that this was a problem with H2, NOT Derby... not sure how I missed that, I've updated (Thanks Nick) Our team recently started using H2 for local development, with our production database being DB2. One nice thing is that the sql dialects for these are nearly identical and you don't need to change the dialect to get things to mostly work. We did, however, hit a snag with our boolean type fields. By default, the values for a boolean object default to "1" and "0" (or 1 and 0) when using the db2 driver and definition the column as a char(1), but when using the h2 jdbc driver (with the DB2 hibernate dialect), the values were getting translated to "true" and "false" which was breaking because obviouly you cannot store 4 characters in a 1 character field. After googling the problem, it turns out a lot of people have run into this and there aren't any obvious solutions float...
