How can I check a data-object for NULL?

Hello,

A sql-statement gives me a field with double-values. The value of this field
can also be 'NULL'. How can I check in a OnPrint-event whether the field is
'NULL' or not?

Thanks,
Daniela

    There is a TField property .IsNull. Does that work?

    TppField.IsNull is supported in RAP. Check the pipeline's current field
    object and check IsNull on that TppField object from the data pipeline:

    if Biolife.FieldObjects['Common_Name'].IsNull then
