I have the following SQL
I am adding to delphi codes this query (db is a mdb-access file)

Select SUM(Hours)
From Empolyee
Where (name = 'name') And (date >=#01-06-2008#  and date <= #04-06-2008#)

This query is not turning anything but it is just making the sum for the all data's belong to the name.
So the date selection is not working.

Any idea why?

By the way.

If I do it (date >=#2008/06/01 #  and date <= #2008/06/04#)
then I get the results. But I need to add it from delphi.

sql.add('Select ...')
sql.add('From ....')
sql.add('Where ??????????)

selection from last 7 days :


sql.Add('WHERE date >= :date1 and date <= :date2');
sql.prepare;
sql.parambyName('date1').AsDateTime := Now - 7;
sql.ParamByName('date2').AsDateTime := Now;
sql.Open;

Can you give the full select/filter statement.

You should be able to use something like
'date >= ' &  StartDAtePicker.Date & ' and date <= ' & enddatepicker.date

Go into MS Access and build your query in SQL form there. When that works, then go into delphi and build it.

You can do something like this:


s := shortdateformat;
shortdateformat := "aaaa/mm/dd";
sql.add('Select SUM(Hours)')
sql.add('From Empolyee')
sql.add('Where (name = "name") And (date BETWEEN ' + QuotedStr(DateToStr(DateTimePicker1.Date)) + ' and ' + QuotedStr(DateToStr(DateTimePicker2.Date)) + '))';
shortdateformat := s;
