Thanks for reading the post,abt the Junk values, details are as follows
1.Data is been inserted from the Front End(Java)
2.an interface is provided to the user to upload the excel file,whose data is been read from the java aplication and then stores the data to the database.
3.nw when we see the data in the database,then junk values are there with the existing data..not only that when we fire a query to find the data in the db for that particular column..then SQL Developer tool gets Hangs Up.
4.The Junk values which we figured out from the table is like (?,and the oppsite sign of ? and reverse of ?)
