In DB2, you can view the change records of table structures by using system views. Here are some commonly used system views:

  1. The SYSCAT.TABLES table
SELECT *
FROM SYSCAT.TABLES
WHERE TABNAME = 'your_table_name';
  1. The catalog table containing information on columns
SELECT *
FROM SYSCAT.COLUMNS
WHERE TABNAME = 'your_table_name';
  1. The catalog table SYSCAT.CHECKS.
SELECT *
FROM SYSCAT.CHECKS
WHERE TABNAME = 'your_table_name';
  1. The index catalog SYSCAT.INDEXES
SELECT *
FROM SYSCAT.INDEXES
WHERE TABNAME = 'your_table_name';
  1. Verification of column definitions
SELECT *
FROM SYSCAT.COLCHECKS
WHERE TABNAME = 'your_table_name';

By querying these system views, you can access the change records of table structures.
