I assure you you will get results, as long as there are values in the
table....
try using:
1) this model in a fresh app
db.define_table('entries', Field('this_is_datetime', 'datetime'))
2) fill some data in
3) create this controller function
def test():
distinct_ = db(db.entries.id > 0).select(db.entries.this_is_datetime.
year(), distinct=True)
sum_of_entries = db.entries.id.count()
grouped_ = db(db.entries.id > 0).select(sum_of_entries, db.entries.
this_is_datetime.year(), groupby=db.entries.this_is_datetime.year())
return locals()
4) you'll get a similar result
distinct_:
web2py_extract('year',entries.this_is_datetime)20152014
grouped_:
COUNT(entries.id)web2py_extract('year',entries.this_is_datetime)3201422015
if there are still issues then, please pack an app that reproduces the
issue....
