Question

I have two table that connect each other. I want it if first table value change it will change value of second table automatically. Any Magic Code for this problem.
this is my first table:

  First table:
      TIMESTAMP            Status
    1/29/2013 08:00          0
    1/29/2013 08:30          0
    1/29/2013 09:00          1

 Second table:
     Status                DATETIME_INPUT
        0                 1/29/2013 08:00
        0                 1/29/2013 08:30

First table control second table, I want every time I add input too First table,
It will automatically change Second Table too.

For example I add last row in First Table but it not change Second Table, I want it
AUTOMATIC CHANGE

Please give some solution

Here is a very basic trigger to insert data in your second table as it gets inserted in your first table.

CREATE TRIGGER trig_Update_SecondTable
ON [FirstTable]
FOR INSERT
AS
Begin
    Insert into [SecondTable] (Status, DATETIME_INPUT) 
    Select Distinct i.Status, i.TIMESTAMP
    from Inserted i
End
