FIELD

FIELD

Specifies the names of the field(s) or group(s) (refer to the GROUP_BY command) that are to be checked for the "null" condition. An expandable group expression is allowed in this parameter.

Note that the relationship between the field(s) in the list is an AND relationship. Thus all fields specified must have null values to satisfy the condition.
