update a table using some conditons
Hi All,
I have a sample table as below:

A B C
A1 B1.ts
A2 B2.ts
A3 B3-ts
i need to have A1-B1 combination( where B column is a name with timestamp which keeps on changing with systemdate) and update C1 column based on B1.Also B2 will be created only after (say) 30 minutes B1 is created.This code should run only once,so what can be done other than using sleep command inbetween those steps? Please help me with the code for table updation.Thanks

Roshita, from the description you have given, I have no idea what output you want to see in any of the three columns. Please give us explicit details of what you want to see in your table (using code tags) at some point in time, what it should look like 30 minutes later, and what it should look like after another 30 minutes.

Is this table in a file? If so, is the file supposed to be updated in place every 30 minutes or is a new file supposed to be created every 30 minutes containing an updated version of the previous file? Otherwise, where is this table stored?
