Your SQL for the check constraint is wrong. You should have made it

CHECK (VALUE IN ('JA', 'NEIN'))

>How can I "tell" the TIB_Checkboxes to use these values?

Once you have a valid check constraint, you can set the BOOLEAN item of the
ColumnAttributes for that domain in your IB_Connection, as follows:

1. In the FieldEntryTypes, make sure that fetDomainName is included in the
set; and
2. In the ColumnAttributes, place this entry:

TBoolean=BOOLEAN=JA,NEIN
