match timestamp with date in MYSQL using PHP - mysql

I have a table
id user Visitor timestamp
13 username abc 2014-01-16 15:01:44
I have to 'Count' total visitors for a 'User' for last seven days group by date(not timestamp)
SELECT count(*) from tableA WHERE user=username GROUPBY __How to do it__ LIMIT for last seven day from today.
If any day no visitor came so, no row would be there so it should show 0.
What would be correct QUERY?

There is no need to GROUP BY resultset, you need to count visits for a week (with unspecified user). Try this:
SELECT
COUNT(*)
FROM
`table`
WHERE
`timestamp` >= (NOW() - INTERVAL 7 DAY);
If you need to track visits for a specified user, then try this:
SELECT
DATE(`timestamp`) as `date`,
COUNT(*) as `count`
FROM
`table`
WHERE
(`timestamp` >= (NOW() - INTERVAL 7 DAY))
AND
(`user` = 'username')
GROUP BY
`date`;
MySQL DATE() function reference.

Try this:
SELECT DATE(a.timestamp), COUNT(*)
FROM tableA a
WHERE a.user='username' AND DATEDIFF(NOW(), DATE(a.timestamp)) <= 7
GROUP BY DATE(a.timestamp);

i think it's work :)
SELECT Count(*)
from table A
WHERE user = username AND DATEDIFF(NOW(),timestamp)<=7

Rewrite sql query to pad empty month rows

I have this query i use to get statistics of blogs in our own tracking system.
I use union select over 2 tables as we daily aggregate data in 1 table and keeps todays data in another table.
I want to have the last 10 months of traffic show.. This query does that, but of there is no traffic in a specific month that row is not in the result.
I have previously used a calendar table in mysql to join against to at avoid that, but im simply not skilled enoght to rewrite this query to join against that calendar table.
The calendart table has 1 field called "datefield" which i date format YYY-MM-DD
This is the current query i use
SELECT FORMAT(SUM(`count`),0) as `count`, DATE(`date`) as `date`
FROM
(
SELECT count(distinct(uniq_id)) as `count`, `timestamp` as `date`
FROM tracking
WHERE `timestamp` > now() - INTERVAL 1 DAY AND target_bid = 92
group by `datestamp`
UNION ALL
select sum(`count`),`datestamp` as `date`
from aggregate_visits
where `datestamp` > now() - interval 10 month
and target_bid = 92
group by `datestamp`
) a
GROUP BY MONTH(date)
Something like this?
select sum(COALESCE(t.`count`,0)),s.date as `date`
from DateTable s
LEFT JOIN (SELECT * FROM aggregate_visits
where `datestamp` > now() - interval 10 month
and target_bid = 92) t
ON(s.date = t.datestamp)
group by s.date

Distinct values when already using count and group by

This is currently the SQL query I am using:
SELECT DAY(time), count(id)
FROM users
WHERE time >= now() - INTERVAL 7 DAY
GROUP BY DAY(TIME)
But it includes repeated email values. How can I get the count by day for only unique email address entries?
Thanks
Solution:
SELECT DAY(time), count(distinct email)
FROM userWHERE time >= now() - INTERVAL 7 DAY
GROUP BY DAY(TIME)

First and last record for a user in a given time period in one query

I am looking to get the first and last record for a given user_id in a time period, for example, 24 hours.
I am aware this could be done using two queries, doing something like this and then switching the ORDER BY ASC/DESC.
SELECT id, user_id, date, other_columns
FROM table
WHERE user_id = 1 AND date > DATE_SUB(CURDATE(), INTERVAL 24 HOUR)
ORDER BY date DESC
LIMIT 1
However, I am wondering if it would be possible to do this using one query.
This is something that you could consider:
SELECT t.id, t.user_id, t.date, t.other_columns
FROM table t
WHERE user_id = 1
AND date = (
SELECT MIN(date)
FROM table
WHERE user_id = t.user_id
AND date > DATE_SUB(CURDATE(), INTERVAL 24 HOUR))
UNION ALL
SELECT id, user_id, date, other_columns
FROM table
WHERE user_id = 1
AND date = (
SELECT MAX(date)
FROM table
WHERE user_id = t.user_id
AND date > DATE_SUB(CURDATE(), INTERVAL 24 HOUR))

MySQL COUNT for days

I want to get the value of users visiting my page for 10 days in a chart. I need to COUNT() all the values from the last ten days.
The best layout would be
Day|COUNT(ip)
1 - 10
2 - 12
3 - 52
......
I hope you understand what I mean.
Can MySQL do this directly or need I to do this in PHP in 10 seperate querys?

Update with Tablestructure:
Id (Auto Increment)|Time (Unix Timestamp)|Ip|Referer
This should run fast for you
SELECT COUNT(ip) ipcount,dt FROM
(
SELECT ip,DATE(FROM_UNIXTIME(`Time`)) as dt FROM mytable
WHERE `Time` > TO_UNIXTIME(NOW() - INTERVAL 10 DAY)
) A GROUP BY dt;
Make sure you have an index on Time
ALTER TABLE mytable ADD INDEX TimeIndex (`Time`);
This will give you results with actual date values:
SELECT
COUNT(DISTINCT ip),
FROM_UNIXTIME(Time, '%m/%d/%Y') AS Day
FROM
tbl
WHERE
Time >= UNIX_TIMESTAMP(DATE_ADD(CURDATE(), INTERVAL -10 DAY))
GROUP BY
FROM_UNIXTIME(Time, '%m/%d/%Y')
try this:
SELECT CAST(DATE(FROM_UNIXTIME(`Time`)) AS CHAR) as dateoftime, COUNT(Ip) as cnt
FROM tablename
WHERE DATE(FROM_UNIXTIME(`Time`)) > DATE_SUB(current_timestamp, INTERVAL 10 DAY)
GROUP BY CAST(DATE(FROM_UNIXTIME(`Time`)) AS CHAR)

MySQL COUNT DISTINCT

I'm trying to collect the number of distinct visits in my cp yesterday, then count them.
SELECT
DISTINCT `user_id` as user,
`site_id` as site,
`ts` as time
FROM
`cp_visits`
WHERE
ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
For some reason this is pulling multiple results with the same site id....how do i only pull and count the distinct site_id cp logins?
Select
Count(Distinct user_id) As countUsers
, Count(site_id) As countVisits
, site_id As site
From cp_visits
Where ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Group By site_id
Overall
SELECT
COUNT(DISTINCT `site_id`) as distinct_sites
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
Or per site
SELECT
`site_id` as site,
COUNT(DISTINCT `user_id`) as distinct_users_per_site
FROM `cp_visits`
WHERE ts >= DATE_SUB(NOW(), INTERVAL 1 DAY)
GROUP BY `site_id`
Having the time column in the result doesn't make sense - since you are aggregating the rows, showing one particular time is irrelevant, unless it is the min or max you are after.
You need to use a group by clause.
SELECT site_id, MAX(ts) as TIME, count(*) group by site_id
