how do i check if the field's value is null?

this code won't work:
if MyDataSet['FIELD01'] = null then
Value := 'Missing'
else
Value := 'Something..';

any idea?

thanks

Tech Tip: RAP: Checking for Null Data Values
----------------------------------------------

The DataPipeline.FieldObjects[] array property provides access to the
TppField objects. TppField has an IsNull boolean property.

The notation is DataPipeline.FieldObjects['FieldName'].IsNull

example:

if Customer.FieldObjects['Addr1'].IsNull then
ShowMessage('field value is null');
