-CHEK CHECK DATA (IBM utility)

If you explicitly create the table space, the command runs as shown below.

However, if you create the table space implicitly, the product adds the character T to the beginning of the command name (–TCHEK) and sets the table space name to the table name.

Execution looks up the table space name during execution and substitutes the table space name for the table name before invoking the utility. You can also use this form because of referential integrity considerations.

For more information, see the IBM DB2 for Utility Guide and Reference documentation.

-CHEK command

The -CHEK command invokes the Db2 CHECK LOB utility on LOB table spaces as required. LOB table spaces must be created and are not created implicitly like XML table spaces.
