Cornie,
select RDB$FIELD_POSITION,RDB$FIELD_NAME
from rdb$index_segments
where RDB$INDEX_NAME = (
select RDB$INDEX_NAME
from RDB$RELATION_CONSTRAINTS
where rdb$relation_name = 'EMPLOYEE'
and RDB$CONSTRAINT_TYPE = 'PRIMARY KEY'
)
order by RDB$FIELD_POSITION;
Replace 'EMPLOYEE' with the table name you wish.
Cheers,
Norman.
