Thread: Please check the code for the errors

Hi all ,
I have to insert some data into orcl databse and select some data from orcl2 databse when my status is null.
Even after executing query in orcl2 status is null then we should stop the process for 5 minutes and then again poll the database and return untill we have some value for status .please let me know does my code works for that logic .If there are any changes please do let me know.It is very urgent please.
