Hello well im desingin my EOModel FINALLY!!!, and well when I set
an attribute the prototype a boolean, the External Type its set to
VARCHAR, shouldnt be BOOLEAN or BOOL or something like that?
Depends. The problem is, that databases model booleans differently
because in the SQL92 standard there was no "boolean". The varchar(5)
that writes "true" or "false" to the database is something that is
more readable than 1 and 0 and still works on all database systems.
Every database, however, handles ints or small ints just fine. So
you're external type can be smallint or tinyint and the valueType can
be 'c' to make it a Boolean.
