Insert data from one table to another

I have a table in which new entries come in every second. The table is just like this: | value1 |data1| Value2| data2| |-|-|-|-| | 1 | Er | 2 | Er| | 3 | Er | 4 | Er| Now insert these value in other table as |Value | data| |-|-| |1| Er| |2| Er| |3| Er| |4| Er| And when new data insert into 1 table insert that data into second one in each execution of query but not previous one.
