I have following table in mysql

| modified | datetime | YES | | NULL | |
| created | datetime | YES | | NULL | |
+-----------------+-------------+------+-----+---------+----------------+
I want to do a query where I pass a list of user_profile_id s and I get their latest record back. Each user_profile_id has multiple records
sql : select id,user_profile_id,latitude,longitude,modified,created from user_locations where user_profile_id in(1044,1259);

Example:
select *,max(created) from user_locations where user_profile_id IN (1044,1259) group by user_profile_id;
This query is wrong, how can fix this?
Thank you
select u.id,u.user_profile_id,u.latitude,u.longitude,u.modified,u.created
from user_locations u where u.user_profile_id in(1044,1259) and u.created =
(select max(g.created) from user_locations g where u.user_profile_id=g.user_profile_id) group by u.user_profile_id;

I need to INSERT or UPDATE data in a table using data from other tables; I understand the basic
insert into table (a,b,c)
select h, i, j
from otherTable
where........
My challenge comes from the fact that the data is spread across multiple tables and in one of the tables the data is metadata stored in rows, not columns. Therefore I need to use JOIN and possible UNION to get what is needed.
Unfortunately after trying everything I read in both the Maria manual, on the Maria forum and on Stack overflow I can not get it to work.
Here is what I am attempting to do:
insert data into dbc_jot_groupmembers in the following fields using source data as shown:
jot_grpid = dbc_bp_groups_members.group_id
jot_bbmemid = dbc_bp_groups_members.user_id
jot_grpmemname = dbc_bp_xprofile_data.value where field_id=3
jot_grpmemnum = dbc_bp_xprofile_data.value where field_id=4
I need the final result to look like this:
select * from dbc_jot_groupmembers;
+--------------+-----------+----------------+---------------+---------------------+-------------+
| jot_grpmemid | jot_grpid | jot_grpmemname | jot_grpmemnum | jot_grpmemts | jot_bbmemid |

If this can not be done is a single INSERT then I can use an INSERT with subsequent UPDATE statements. I also understand that this is not best practice and violates 3nf and probably several other best practice principles. Unfortunately, I am at the mercy of the application and can not change the code, so the only way to get this to work is to put duplicate data in the database as described below:
It can be done with a single INSERT. However, there are some information need to be addressed as what I've posted in a the comment. In the meantime, here is an example query that you can use to do the operation that you want:
SELECT ROW_NUMBER() OVER (ORDER BY A.group_id, A.user_id) AS 'jot_grpmemid',
A.group_id AS 'jot_grpid',
MAX(CASE WHEN B.field_id=3 THEN B.value ELSE '' END) AS 'jot_grpmemname',
MAX(CASE WHEN B.field_id=4 THEN CONCAT('+',B.value) ELSE '' END) AS 'jot_grpmemnum',
A.user_id AS 'jot_bbmemid'
FROM
dbc_bp_groups_members A JOIN dbc_bp_xprofile_data B
ON A.user_id=B.user_id
GROUP BY A.group_id, A.user_id;
Like I said in the comment, I'm not sure how you get/generate jot_grpmemid because you have two 7 in the expected result so I assume it's a typo. I guess, at this point it's up to you to modify the query accordingly.

I have a MySQL table that looks like this:
+-------------+---------+------+-----+---------+-------+
| Field | Type | Null | Key | Default | Extra |
+-------------+---------+------+-----+---------+-------+
| person_id | int(11) | NO | MUL | NULL | |
| location_id | int(11) | NO | MUL | NULL | |
| date_signed | date | NO | | NULL | |
| date_ended | date | YES | | NULL | |
+-------------+---------+------+-----+---------+-------+
Where all of the records are like this:
+-----------+-------------+-------------+------------+
| person_id | location_id | date_signed | date_ended |
+-----------+-------------+-------------+------------+
| 1 | 49 | 2007-09-29 | NULL |

| 5 | 37 | 2009-01-09 | NULL |
| 5 | 32 | 2009-10-08 | NULL |
+-----------+-------------+-------------+------------+
I'm trying to update each person's date_ended to be one day less than the date_signed in the next chronological row for that person:
+-----------+-------------+-------------+------------+
| person_id | location_id | date_signed | date_ended |
+-----------+-------------+-------------+------------+
| 1 | 49 | 2007-09-29 | 2010-10-08 |
| 1 | 41 | 2010-10-09 | NULL |
| 2 | 45 | 2007-09-29 | 2007-12-15 |
| 2 | 58 | 2007-12-16 | NULL |
.
.
.
But I can't figure out how to select the next chronological record. I tried a few suggestions from similar questions:
UPDATE a column based on the value of another column in the same table
Mysql - update table column from another column based on order
ROW_NUMBER() in MySQL
But I couldn't get them to work. Is there a way to do this in MySQL?

I want to know how to get sum of every 5 vol, means from ID 1 to 5, then 6 to 10 .....continues by ticker.
sorry for creating confusion at the first time.
Try this:
SELECT sum(column), floor((id-1)/5) + 1 as min_id
FROM table_name
GROUP BY min_id
Try this
SELECT SUM(vol)
FROM (
SELECT vol, TRUNCATE(id/5,0) AS id
FROM eod) AS t
GROUP BY id
Not tested but logic is correct
this is probably something very noob of me

outputs like this (from_id 282 is missing)

| 29883054 | 409699 | 100 | 2013-07-26 15:22:35 |
any idea how this can be avoided ?
EDIT: forgot to mention, the goal is to return only one row per from_id.
What about the query
select id,from_id,to_id,date from mail where to_id='100' order by id, from_id desc limit 50;
That should work, hopefully.
