(When I applied this the new values are coming 2 times)
The table1 data will be extending, the C1 value will be constant and C2 values will be added(At a time It might add N number of rows). If any Value to table1 is added that has to be reflected in Table2 also. That is the main changes has to be done. But the values to Table2(C3, C4, C5) has to be taken by comparing the C1 value.
