ALTER TABLE Curve_W_Sign
ADD CONSTRAINT fk_Curve
FOREIGN KEY (Support_ID)
Msg 547, Level 16, State 0, Line 1
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "fk_Curve". The conflict occurred in database "CNTY_GIS", table "dbo.Asupport_Sign", column 'Support_ID'.
Within my "Child" table i do have duplicates of the ID that are in the Support_Sign table which i thought should be ok? is it? The Parent Table can have multiple ID's in the "Child" Tables right?
