[EpiData-list] How to: select with dates and an open question ? ?

This should work: * ---------------------------------------- DEFINE DATEMIN <dd/mm/yyyy> DEFINE DATEMAX <dd/mm/yyyy>

LET DATEMIN = dmy(? First date: e.g. (02/12/1989) ?,"dmy") LET DATEMAX = ? Second date : e.g. (02/12/1999) ?,"dmy")

SELECT (DATEADM <= DATEMIN) AND (DATEDIS >= DATEMAX) FREQ AGE ................................................................

or to select directly in comparison with a specific date using the dmy function:

select date(? Write date, dd/mm/yyyy ?,"dmy") > dmy(10,02,1999)
