I just realized that the "weekday" is not working as and believed, but is
much easier. I can make simple queries of the form:
select * from dates WHERE date = date ('2011-12-09 ',' weekday 5 ');
Or
select * from dates WHERE date <= date ('2011-12-04 ',' weekday 6 ');
And they work properly. But I can not use this selection criterion with
periods defined by the operator "between" using "X> = Y and X <= Z"
I'm testing with a simple table:
CREATE TABLE fechas (
id integer primary key autoincrement,
fecha numeric not null
);
