How to update data from one table column to another table column?
===

In my Application I am using sqlite database,


I have two table

        **Tbl1**       |   **Tbl2**
                   |
    CustID OldId   |   CustID 
                   | 
       1     5     |     5
       2     10    |     10
       3     15    |     15

Now I want to set CustID in Tbl2 from tbl1 that machining to OldId data.

I want to get data like this,

      **Tbl2**

      CustID 
                   
       1     
       2    
       3     
    


Please any one suggest me how can i do that?
