DB2 rename a table and view table information

I believe everyone has some knowledge about the DB2 RENAME TABLE. The following describes how to rename a table in DB2 and view the table information. If you are interested, take a look.

DB2 RENAME TABLE
You can use the RENAME statement to RENAME an existing table. For example:

C: \> db2 rename table tta to rn_tab

The DB20000I SQL command is successfully completed.

When you rename a table, the source table cannot be referenced in any existing definition (view or materialized query table), trigger, SQL function, or constraint. It cannot have any generated columns (except the ID column), or be a parent or slave table. Directory entries are updated to reflect the new table name.

View table information
You can use the commands shown in the table to obtain table information.
