Field Reqd

< All Topics

“Non-null required” status of a field. Indicates whether a value other than $Null is always required for the field in an ADD or CHANGE command.

Valid Values

As shown in the table below:




(DEFAULT) The field need not be assigned a non-null value


The field must always be assigned a non-null value, either explicitly or by the field’s default attribute (see Default)



During an ADD command, if no value is required and none is assigned, the field’s value is set to its specified default value, which may be $Null.

Reqd is not used for fields that belong to documents.
