MYSQL :: Trying To Retrieve Most Recent Record Per Date

Retrieve Most Recent Rows
I have a simple table with four columns. ID (auto_increment), username, score, and date (unix timestamp). How could I, if possible, get the past 10 scores of each unique username? So if there were 15 different usernames, I would get 150 rows returned (assuming all of them had played 10+ games). Can this be done in a single query or do I need to run a query for each username?

Retrieve Most Recent Records From Database Sorted By String Value
I'm having a problem with a simple select query. I've got users
uploading data into a database. I want to do something that seems as if
it should be really simple, but it isn't so far.

Basically, I want to retrieve the latest 12 records from the table,
sorted by the date-time field (uploaddate) then by a varchar field
(name). Here's the SQL that I'm using:

select * from tblcontent
where filetypeid=1 and release='Y'
order by uploaddate desc, name limit 12;

And here's the table schema:

Field,Type,Null,Key,Default,Extra
ContentID,int(3),,PRI,NULL,auto_increment
Name,varchar(50),,,,
Filename,varchar(100),,,,
Thumbnail,varchar(100),,,,
FileTypeID,int(11),,,0,
UploadDate,datetime,,,0000-00-00 00:00:00,
Description,text,,,,
ContributorID,int(10) unsigned,,,0,
Release,enum('Y','N'),YES,,N,

The problem I'm running into is that while I am retrieving the most
recent 12 records, it's not sorting by the varchar field. Instead, the
'Name' field seems randomly sorted. If I change the sort order (name,
uploaddate desc), I don't get the records that I want.

This seems like it should be something very simple to do, but it's
driving me nuts and I really have no idea how to resolve the problem. Code:

ORDER BY :: Most Recent Date
I have dates recorded in my database for my website, in a var char in this format: 4/8/07, 4/21/07, 4/22/07, 4/10/07, etc. When I use order by to try to order by the most recent date, it doesn't work.

I even know why, and it's because it'll put 4/8/07 before 4/21/07 because there is no 0 before the 8, so it sorts it as 8 larger than 2, which it is. Is there any way to get around this, so it will order correctly?

Automatically Record Date Of Record Entry
I have my database table set up and I have an HTML form that is PHP driven that will add the information entered into the form into to my database table.

I have a local buy-sell-trade Website. The way it has worked is that people fill out a form and the results emailed to me. I then take the information and enter it into a Web page. I only want the ads to be displayed for 30 days. I keep the ad for a total of 6 weeks (displays for 30 days and sits in limbo for 2 weeks afterwords) and if not renewed within that 2 week limbo period - I delete it.

Entering all the ads and keeping up with the dates manually has become a burden. I've only recently began looking into databases. My hosting company provides me with phpmyadmin and mysql 5.0. I'm new to all of this but I have managed to set up a database table and a HTML form that is PHP driven that allows ads to be automatically added to the database table.

There is a lot I need to do to make this ideal, but one step at a time.

First, I need to know the date (March 02, 2006) the ad was created or added to the database table. I know that I need to add some piece of code to my php form to record this information, but what code and where do I put it? I know I will need to create an extra field in my database table to house the date - I can handle this.

I've read the date and time information here http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html

but there's a lot there and I don't know which is right for my needs. Plus, it doesn't tell me how or where to insert it into my php form (or does it?).

How To Retrieve Latest Date
I have a table that looks something like this:

table prop1 {
id;
addr;
zip;
name;
} (it's much larger than this)

And another table that looks like

table prop2 {
id;
price;
date;
}

The first table will have one entry per address. The second can have any number of entries with varying prices and dates. I need to retrieve the highest price with the latest date from prop2 for each entry in prop1.

I have tried this code:
select (p.id, p.addr, pp.id, pp.price, pp.date, MAX(pp.price) from prop1 p, prop2 pp where p.id = pp.id group by p.id order by p.addr);

This sort of does what I want. But it lists all of the results. So if one address has ten entries, all ten entries are returned. If I add a LIMIT 1, that works for the first address but no others are returned.

Is there a way to return just one entry for each address and have that entry be the one with the highest price and most recent date (or even just the highest price if need be)?

Sorting By Latest Date Field In Each Record
I have a MySQL table with the following fields:

ID (int 11) (PK)
Company (varchar 50)
Contactdate (date)
Formdate (date)
Signdate (date)

I would like make a select query that orders the records by the most
recent date (i.e. descending) of any of the three date fields and then
by company name. Some date fields may be empty (null) A record must not
be listed more once.

For example, if I have the following data:

ID, Company, Contactdate, Formdate, Signdate
1, acme1, 2006-01-01, 2006-01-10, Null
2, acme2, 2006-01-01, 2006-01-11, 2006-01-12
3, acme3, 2006-01-08, 2006-01-09, 2006-01-09

The result should be:

2, acme2
1, acme1
3, acme3

In other words, the query should determine the 'latest date
field activity' of each record and then order by that date (and then by company).

If it is complicated to use null values I can also set the default
value of the date fields to something like '1900-01-01'.

How To Check For Date/time Ranges Within Record (check For Schedule Conflicts)
You want to check scheduling conflicts and you have a record like:

appointments(table):
apptID
beginningDate
endingDate
beginningTime
endingTime

It's easy enough to check if a time is within that record. Say you want to
check if 8:00am to 10:00am is available, you would use this:

SELECT apptID
FROM appointments
WHERE (beginningDate = '2006-01-19' OR endingDate = '2006-01-19')
AND ('08:00:00' BETWEEN beginningTime AND endingTime
OR '10:00:00' BETWEEN beginningTime AND endingTime)

BUT, what if you have an all-day appointment (8:00am to 5:00pm) and there
exists an appointment already scheduled from 10:00am to 11:00am. The above
query would not find it.

Another question is what if the appointment is more than two days. Say, it's
from Monday - Wednesday from 8am to 5pm. The above query would not
successfully catch it if you wanted to schedule an appointment on Tuesday.

(I might be able to generate a date range using PHP, don't know if that's
the best way)

Get Most Recent Version Of An Element

each element, which would then be returned in "select" but this doesn't
seem to be working. Any elements with multiple versions are simply not
returned.

I could swear that I have used a similar approach in the distant past

8, 1233, 2006-06-28, note
13, 1233, 200-07-24, note

he will get selected from my query since two of his previous notes have a date_of_interest before today but I really only want to care about the most recent of notes so he shouldn't get selected. Is there a way to do this in the query or should I add another field to the database to mark it as the most recent.

Left Join To Get The 1 Most Recent
Firstly table structure - 1 user has multiple status records. When a new status record is created it gets the current datetime inserted into 'date_created'.

user
user_id
site_id

status
status
notes
date_created

I wish to display a list of all users and show beside them their current/most recent status record. Here is my code currently:

SELECT user.*, status.date_created, status.status, status.notes,
DATE_FORMAT(status.date_created,'%l:%i %p') as last_updated_time,
DATE_FORMAT(status.date_created,'%e/%c') as last_updated_date
FROM user
LEFT JOIN status ON status.user_id = user.user_id
WHERE user.site_id = 1
GROUP BY user.user_id
ORDER BY
CASE user.user_id WHEN 8 THEN 0 ELSE user.user_id END

Currently via the LEFT JOIN and GROUP this does display a list of all users with 1 status record per user but it's simply the first status record in the table (ordering by id i guess), not the most recent. How can I get it to display the most recent instead, based on date_created. I've tried adding ordering to the left join but this returned an error.
