I'm bringing data from a database every 1 minuite.

Data is three kinds.

Data type is

1. 2013-02-01 13:12:01;i;OS0001; ~~~
2. 2013-02-01 13:12:04;d;OS0001; ~~~
3. 2013-02-01 13:13:06;u;OS0001;~~~

=> "i" is insert, "d" is delete.

, "u" is update, OSC001 is PK.

Can you calculate in case "d" data comes "i" next time?
