Wie heißt denn die Domain für die SmallInt Spalte?

Q3: How can I force FireDAC to recognize some field as boolean?
A: A boolean field may be created using a domain. The domain name must contain 'BOOL' substring. Also, add ExtendedMetadata=True parameter to your connection definition. For example:
CREATE DOMAIN T_BOOLEAN SMALLINT;
CREATE TABLE ... (
...
BOOLEAN_FIELD T_BOOLEAN,
...);
