hi lagen004,

FROM customers
WHERE customers.'entry date' < {TDateTime = Integer}

You must give an integer value, not a string value, because dates or in TDateTime formats. You get the TDateTime format of '01-01-1998' by calling StrToDate('01-01-1998') or StrToDateTime()

SQL needs a specific format for Dates

'MM/DD/YYYY' , 'MM/DD/YY' or 'dd-MMM-YYYY'

SELECT * FROM customers
WHERE customers.'entry date' < "01/01/1998"

For ZifNab:- TDateTime is Float NOT and Integer

and what you have written is not a legal SQL statement.
