I am retreiving FK's from a FB database, but now i need to know weather the FK's are 1:1, 1:m or what ever.
Here is the sql that i have at the momment. How would i go about retreiving only the 1:1 and then the 1:m in different SQL statements? In MS Sql 2000 there is flags in the Information schema tables that will give me this info, but how do i find this out with FB?
C.RDB$RELATION_NAME as FK_Table,
D.RDB$FIELD_NAME as FK_Field,
E.RDB$FIELD_NAME as OnField,
from RDB$REF_CONSTRAINTS B, RDB$RELATION_CONSTRAINTS A, RDB$RELATION_CONSTRAINTS C,
RDB$INDEX_SEGMENTS D, RDB$INDEX_SEGMENTS E, RDB$INDICES I
where (A.RDB$CONSTRAINT_TYPE = 'FOREIGN KEY') and
(A.RDB$CONSTRAINT_NAME = B.RDB$CONSTRAINT_NAME) and
(B.RDB$CONST_NAME_UQ=C.RDB$CONSTRAINT_NAME) and (C.RDB$INDEX_NAME=D.RDB$INDEX_NAME) and
and (A.RDB$RELATION_NAME = 'JOB')
order by A.RDB$RELATION_NAME, A.RDB$CONSTRAINT_NAME, D.RDB$FIELD_POSITION, E.RDB$FIELD_POSITION
