Key Violation(Urgenlty)

[Walter Thizo]

Morning Programmers


I have given project where there is corrupt database in the form of text file , what they need is paradox Boland c++ database that will handle the duplicates of student no and make it primary key on the student table. What i have done so far i was able to extract student no from the file but when i save to my field student_No(Primary Key), Error message pop up Key Violation.

My Question

How can avoid key Violation because i know it causes by same record that must be unique to its field.?

Thanks in Advanced

If it is going to be used as primary key then you must first check whether that student number already present in table.
Or you can put the things in try catch block and simply bypass the "key violation" exception.
