SQL Server：如果在一个表中插入一行，我如何编写触发器以在不同的表中插入同一行？

Question

I'm not sure how to create this trigger,.I need to add a row in pub_info table when a row is inserted in publishers table. The exact same row. SQL server

CREATE TRIGGER checkCity
ON pub_info
AFTER INSERT
AS
IF -- a row is inserted into publishers table, 
   -- how do I add the same row into pub_info table?
INSERT VALUES(@pub_id, NULL, 'new publishers')
BEGIN
END;

Answer 1

You have to create a trigger on publishers table and not on pub_info . The inserted data is available in the INSERTED table in the trigger

CREATE TRIGGER checkCity
ON publishers
AFTER INSERT
AS
BEGIN
  INSERT INTO pub_info(pubid, pubname, pub_description)
      SELECT pubid, pubname, pub_description 
      FROM INSERTED;
END;
