[TypeError：无法将datetime.datetime与元组进行比较]：如何使用Python和SQLite3将元组值与datetime值进行比较？

Question

I am using the SQLite3 module within Python and I currently have a table that stores a "date" as datetime. However, whenever I try to retrieve that date from the table and compare it to today's date (eg today = datetime.datetime.today()), I get an error that says:

if row > today:

TypeError: can't compare datetime.datetime to tuple"

Here is a snippet of the code that I am having trouble with:

for row in con.execute('select time_date as "d [datetime]" from fault_record'):

if row < today:
    print row

I am stumped on how to convert the tuple date to a datetime?

Thanks!

Answer 1

Rows are returned as tuples of columns, even if there's only one column.

Changing

for row in con.execute('select time_date as "d [datetime]" from fault_record'):

to

for date, in con.execute('select time_date as "d [datetime]" from fault_record'):

will iterate over the dates, instead of the row tuples.
