Thanks for your response. However, my batch inserts and the uniqueness of
my timestamps aren't the issue. I guess I didn't explain my situation well
enough. Let me try again.
I take readings every X seconds which gives me plenty of uniqueness for each
reading. I save the SQL statements and then insert them in small batches.
However, from reading this newsgroup I've learned that the correct way to
put dates into SQLite is as I described before:
- create table my_table(date_stuff real);
- insert into my_table values(julianday('now'));
In my batch loop, I can't use julianday("now") - I need the timestamp
to reflect when I took the reading.
If the right way to put datetime in the dbase is the julianday('now')
format, I need to be able to create and capture that format in python.
What is the julianday("now") equivalent in python? I can't find a simple,
straight-forward answer to this question.
Thank you,
Chris
