Here's another simple testcase that fails for Oracle beta5 but works
with 0.3.7. It's about the simplest query I can come up with. Have a
table with a date column in it and query against it using the
"to_date" function.
def test_to_date():
start_date = '10/05/04'
where = cal_dim.c.adwkenddt == func.to_date(start_date,'MM/DD/RR')
query = select([cal_dim.c.adwkenddt],
whereclause=where
)
result = query.execute()
for r in result:
print r
This fails for beta5, works for .3.7. The error is::
Traceback (most recent call last):

Am still confused as to the problem here.... I run the same query
through text and it works::
def test_to_date_text():
s = text("""SELECT "AD_WEEK_CALENDAR_DIM".adwkenddt
FROM "AD_WEEK_CALENDAR_DIM"
WHERE "AD_WEEK_CALENDAR_DIM".adwkenddt = to_date(:to_date, :to_date_1)""")
result = connection.execute(s,
to_date_1= 'MM/DD/RR',
to_date= '10/05/04')
for r in result:
print r
