Junk Characters getting inserted in DB (Oracle)

[Ramesh Jothimani]

I am having two tables.From first table I am taking value of one column and inserting the same into second table. I am not making any changes to the value inbetween but I am using it to fetch some other values.While inserting the value from first table to the second table , the value appears to be a junk one appeneded with some special characters. Please suggest a solution.

Thanks
