My goal is to have the [PYes/No] column indicate a Yes or No if the [PdDate] column is less than today’s date, when I open up the tblData A. My [PYes/No] data type is Yes/No and in the properties of the [PYes/No] field I have entered in the Validation Rule: IIf([PdDate]<Now(),"Yes","No"
. An error displays the following when I try to save the changes: Invalid SQL syntax – cannot use multiple columns in a column-level CHECK constraint. Is there another way to word this, without having to do a separate query?
