Spotlight on DB2 6.10 - Release Notes

Rows Updated Internally

The number of rows updated in the database as a result of internal activity generated by this SQL statement.

Internal update activity can result from these events:

• A SET NULL row update enforcing a referential constraint defined with the ON DELETE SET NULL rule

• A trigger being fired

If this statement causes a large number of internal updates, you might re-evaluate the design of the table referenced in the statement to determine whether the referential constraints defined for the table are necessary.
