COBOL-DB2 Program Interview Question: Accessing Record Beyond Table Limit

COBOL-DB2 Program Interview Question

In a COBOL-DB2 program, what happens when trying to access a record beyond the table's limit?

When attempting to access a record beyond the table's limit, such as trying to access the 100th record when the table has only 50 records, an error or exception is usually thrown by the DB2 system. This error indicates that the requested record does not exist within the specified range of the table.

Developers need to handle such situations by implementing proper error-checking and handling mechanisms in the COBOL-DB2 program to prevent crashing or unexpected behavior. It is essential to validate the record index against the table's actual size before accessing it to avoid such boundary-related issues.

Understanding the table's limits and implementing robust error-handling procedures can help ensure the stability and reliability of COBOL-DB2 programs when dealing with data retrieval operations.
