Hello.
According to the manual Unix timestamp (seconds since '1970-01-01
00:00:00', so, in my opinion UNIX_TIMESTAMP is not designed for
obtaining microseconds. Have a look here, if you haven't done this
yet:

i have this query:
SELECT COUNT(*) AS score FROM downloads WHERE date_add(dateline,
interval 1 hour) = now() GROUP BY filename ORDER BY score DESC
unfortunately for other reasons i had to change `dateline` to unix timestamp so this query is no longer able to run as intended. can anyone help

It would be better with
WHERE dateline = UNIX_TIMESTAMP() - 3600
so that it can use an index on dateline.

Hello,
I have been pulling my hair out trying to get a SELECT statement to work
using a range of Unix timestamps as the criteria.

Why do you have FROM_UNIXTIME() in the WHERE clause? You said
the time column was already in Unix time, and regardless, you're
passing the function the

I think you need this function
FROM_UNIXTIME(unix_timestamp,format).
Year does not operate on a unix timestamp.
Sure it does:
mysql select t, year(t) from tsdemo1;
++-+
| t | year(t) |
++-+
| 20010822133241 |2001
this function
FROM_UNIXTIME(unix_timestamp,format).
Year does not operate on a unix timestamp.
Working like a charm. My query now is:
SELECT DISTINCT FROM_UNIXTIME(created, '%Y %M') FROM table_name ORDER BY
created DESC
How can I add more fields to query. If I write:
SELECT DISTINCT FROM_UNIXTIME
am I doing wrong?

I loose distinction (all dates are displayed).

I don't think distinction is lost. All the rows should still be distinct

You're right. You'd have to apply YEAR() to
FROM_UNIXTIME(UNIX_TIMESTAMP(arg)).
and you can avoid YEAR() altogether by using a
format string. in FROM_UNIXTIME()

monthandyear must be replaced by your function
which extracts month and year from the unix timestamp column
(in both the select and group by).
I think that's what you needed.

There seems to be a flaw in the myODBC driver
02.50 when working with the Unix-Timestamp()
function.
Apparently, the driver doesn't know which
data-type to use...
When I send the sql statement:

Select
( UNIX_TIMESTAMP(U.lastTime
that does the trick.
My guess is that the ODBC driver is
behaving badly in this case ...
