It would also help if you provided us with proper information. The SQL logic you provided does not work!

CREATE TABLE DELAYSECONDS(

ProgramID INT, ID INT, ContractHeaderID INT StationID INT ContractStartTime TIME ProgramStartTime TIME ContractDetailFirstDay INT ProgramFirstDay INT DelaySeconds INT)

INSERT INTO DELAYSECONDS

VALUES (625, 625, 115278, '0:00:00', '18:00:00', '18:00:00', 2, 2, 0),

(623, 623, 115279, '0:00:00', '8:00:00', '15:05:00', 1, NULL, 0),

(624, 624, 115280, '0:00:00', '18:00:00, '19:00:00', 7, 7, 0),

(625, 625, 115281, '0:00:00', '18:00:00', '18:00:00', 2, 2, 0),

(625, 625, 115282, '0:00:00', '19:00:00', '18:00:00', 2, 2, 3600)

The above SQL has a few errors in it.
