Question

我有两张表stock和purchase表 我希望将数据插入purchase表时stock表 应该通过插入purchase表来更新如何操作？

Answer 1

CREATE TRIGGER trigger_insert_stock
AFTER INSERT
ON purchase
AS
BEGIN
  INSERT INTO stock (att1, att2)
    SELECT att1,att2 FROM INSERTED
END

Answer 2

试试这个：

CREATE TRIGGER trigger_int
ON purchase
FOR INSERT
AS
BEGIN
  INSERT INTO stock (order_id, name, price)
    SELECT
      order_id,
      name,
      price
    FROM INSERTED
END
