CREATE TABLE A (Id INT IDENTITY(1,1), Name VARCHAR(50))
CREATE TABLE B (Id INT IDENTITY(1,1), Name VARCHAR(50), Aid INT)
GO
CREATE TRIGGER TriggerToAddAutoIntoTableB ON A
AFTER INSERT
AS
INSERT INTO B (Name,Aid)
SELECT i.Name,i.id
FROM inserted i
GO
INSERT INTO A (Name) values ('A1')
INSERT INTO A (Name) values ('A2')
INSERT INTO A (Name) values ('A3')
