PHP - Select * From Order By Id Tables

How can i select the last 3 rows in a table and order it by ASC. When i use DESC it displays the results in the wrong order.

$query24 = mysql_query("SELECT * FROM notifications WHERE to_id='$session' AND state='1' ORDER BY id DESC LIMIT 3 ");

Hey guys, I am having trouble figuring this out. I currently have a database that automatically sorts itself by the id of the data. But, I am wanting the user to be able to change the sort order via a select box. I already have the select box programmed with the options, but I am not sure how to go about coding the options to change the sort order of the displayed data. What would the best way to go about programming this be?

Thank you very much ahead of time!!

I have 2 queries that I want to join together to make one row  

Hi there I have 2 tables:

Fleet
FleetName
PlanetName
Status

Planet
PlanetName
PlayerName

Im trying to write a select query that will search through the fleet table and display Fleet table details Where the PlanetName from the fleet table is = to the PlanetName of the Planet table. Ive tried joining the tables but i dont think the logic quite works..

Code: [Select]
mysql_select_db($database_swb, $swb);
$query_Fleet = sprintf("SELECT fleet.FleetName, planet.PlanetName FROM fleet, planet WHERE fleet.PlanetName = planet.PlanetName");
$Fleet = mysql_query($query_Fleet, $swb) or die(mysql_error());
$row_Fleet = mysql_fetch_assoc($Fleet);
$totalRows_Fleet = mysql_num_rows($Fleet);

I want ONLY the Fleets from the planet i am looking at to be displayed not all of them. I have created another query that displays the planet name of the particular one I am looking at as it is parsed from a hyperlink on a previous page. So is there some way i can use both queries together?

"SELECT FROM fleet, WHERE $fleet.PlanetName = $planet.PlanetName"

Im a little bit confussed, please help

hey,
i'm trying to select information from 2 tables in one query...
so i have 2 tables...

members - (holds the members information)
looks like this:
Code: [Select]

+---+--------+------------+------------+
| id | name  |    email    | password |
+---+--------+------------+------------+
|  1 | user1 | 1@g.com | ****       |
|  2 | user2 | 2@g.com | ****       |
|  3 | user3 | 3@g.com | ****       |
|  4 | user4 | 4@g.com | ****       |
|  5 | user5 | 5@g.com | ****       |
|  6 | user6 | 6@g.com | ****       |
+---+--------+------------+------------+


the second table is profile_views
which stores the profile views...
Code: [Select]
+---+--------+-----------+---------------+
| id | userid | viewerid |       time      |
+---+--------+-----------+---------------+
|  1 | 4        | 1           | 1287949172 |
|  2 | 6        | 2           | 1287949172 |
|  3 | 2        | 4           | 1287949172 |
|  4 | 4        | 5           | 1287949172 |
|  5 | 3        | 2           | 1287949172 |
+---+--------+-----------+---------------+


userid - the profile (member) id that been watched
viewerid - the id of the member who watched
time - the time this happened

im trying to select from profile_views the viewers ids' and select the info from the members according to the viewerid, but also i want to select the time from the profile_views, so it's should look like this:
Code: [Select]

+---+--------+------------+----------+------------+
| id | name  |    email    | password |  time
+---+--------+------------+----------+------------+
|  1 | user1 | 1@g.com | ****        | 1287949172
|  2 | user2 | 2@g.com | ****        | 1287949172
|  3 | user3 | 3@g.com | ****        | 1287949172
|  4 | user4 | 4@g.com | ****        | 1287949172
|  5 | user5 | 5@g.com | ****        | 1287949172
|  6 | user6 | 6@g.com | ****        | 1287949172
+---+--------+------------+----------+------------+


this is my code:
Code: [Select]
$DB->query("SELECT viewerid FROM profile_views WHERE userid={$core->input['showuser']} ORDER BY time DESC LIMIT 5");

if ( $DB->get_num_rows() > 0 )
{
while ( $all_viewers = $DB->fetch_row() )
{
$viewers_ids[] = $all_viewers['viewerid'];
}

$viewers_ids = implode(",", $viewers_ids);


$DB->query("SELECT m.*, v.*
                                FROM members m
                                LEFT JOIN profile_views v ON (v.userid=m.id)
                                WHERE m.id IN ({$viewers_ids})");

while ( $viewers = $DB->fetch_row() )
{

}
}

but it's just dont work!
any ideas?

Thanks in advance!

hey,
i trying to select * colums form one table and 1 colum from another table...

Hi guys,

This is my first time posting here - im just getting into PHP - i got a question;

I have two databases:

profile(id, name, interests, dob, gender, join_date, email)
interests(id, profile_id, interests)
id being the primary key, and profile_id being the foreign key from profile.

I want to script that returns profile information and all the matching interests (one user can have multiple interests).

This is what i have so far, though it does not work, and i knew it wouldnt;

function get_profile($id) {
   $connection = mysql_open();
   $query = "SELECT * ";
   $query .= "FROM profiles, interests ";
   $query .= "WHERE profile.id=" . $id;
   $query .= " AND interests.profile_id=" . $id;
   $result = @ mysql_query($query, $connection);
   // Transform the result set to an array (for Smarty)
   $entries = array();
   while ($row = mysql_fetch_array($result)) {
      $entries[] = $row;
   }
   mysql_close($connection) or show_error();;
   return $entries;   
}


Can someone please advise on how this can be done? or do i need to have two query's one for each table ?

Thank you in advance!!

I'm having a hard time grasping how to select data from several tables.

Here's the code

Code: [Select]
<?php 
require_once "config.php";
$gamedate = $_SESSION['date'];
echo "These umpires are not currently scheduled on this date, and have not asked for the day off:<br />";

$umpirelist = Array('umpire 1 name', 'umpire 2 name', 'umpire 3 name');

$dbc = mysql_pconnect($host, $username, $password);  
mysql_select_db($db,$dbc);  

foreach($umpirelist as $data) { 

//now get stuff from a table           
$sql = "SELECT calendar.date, calendar.ump1, calendar.ump2, calendar.ump3, calendar.ump4, calendar.ump5, vacation.date, vacation.umpire FROM umps, calendar, vacation WHERE umps.full_name = $data AND $gamedate = `calendar.date` AND $gamedate = `vacation.date` AND $data NOT IN ('calendar.ump1', 'calendar.ump2', 'calendar.ump3', 'calendar.ump4', 'calendar.ump5') AND $data NOT IN ('vacation.umpire') order by umps.full_name asc"; 

$rs = mysql_query($sql,$dbc);  
$matches = 0; 
while ($row = mysql_fetch_assoc($rs))  {
$matches++; 
echo "$row[$data]<br />";
}
}
?>

The table CALENDAR holds the date of the game, who is playing, and what umpires are schedule for that game.  it does have a unique "row_number" column as well, but didn't think I'd need it in this select.

The table VACATION has the date, and umpire's name that is on vacation.

The table UMPS contains the umpires name (same names as the array in the code) and email addresses and login info.

I'm getting this error:

Quote

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource on line 152



This is line 152

while ($row = mysql_fetch_assoc($rs))  {



Can someone please point me in the right direction as to where I'm going wrong?

Thanks!

Hi,   How can I select multiple columns from two tables and run a search through multiple fields?   My tables a   t_persons (holds information about persons) t_incidents (holds foreign keys from other tables including t_persons table)   What I want is to pull some columns from the two tables above and run a search with a LIKE criteria, something like below. The code originally worked well with only one table, but for two tables it generate errors:

$query = "SELECT
p.PersonID
,p.ImagePath
,p.FamilyName
,p.FirstName
,p.OtherNames
,p.Gender
,p.CountryID
,i.IncidentDate
,i.KeywordID
,i.IncidentCountryID
,i.StatusID

FROM t_incidents AS i
    LEFT JOIN t_persons AS p ON i.PersonID = p.PersonID
WHERE
    FamilyName LIKE '%" . $likes . "%' AND
    FirstName LIKE '%" . $likes . "%' AND
    OtherNames LIKE '%" . $likes . "%' AND
    Gender LIKE '%" . $likes . "%' AND
    IncidentDate LIKE '%" . $likes . "%' AND
    KeywordID LIKE '%" . $likes . "%' AND
    IncidentCountryID LIKE '%" . $likes . "%' AND
    StatusID LIKE '%" . $likes . "%'
ORDER BY PersonID DESC $pages->limit";

Errors a

Column 'IncidentDate' in where clause is ambiguous
Column 'KeywordID' in where clause is ambiguous
Column 'IncidentCountryID' in where clause is ambiguous
Column 'StatusID' in where clause is ambiguous

These columns are foreign keys on t_incidents table. I have also attached the table relationship diagram if it helps.   I will appreciate any better way to do this.   Thanx.   Joseph Attached Files  Model - 3.png   76.6KB   0 downloads

I am working on a quiz app

image 1 shows the index.php page
image 2 shows the first question
image 3 shows the second question
image 4 shows the third question
image 5 shows the result after completing the quiz
image 6 shows the database 'quizzer' and its tables
image 7 shows the 'questions' table
image 8 shows the 'choices' table

THIS LINK CONTAIN ALL THE CODE (and images) I HAVE DONE SO FAR

https://www.mediafir...o7f5q0fe6y/quiz

1.Now my question is how to select the question RANDOMLY from 'questions' table along with 'choices' (by adding code to the existing file or create a new one).

2.If user refresh/reload the page before starting ('Start Quiz') or click 'Take Again' after finishing the quiz, the question should appear randomly.

3.Basically I want to change the order of question appearing in the browser each time I refresh.

4.My work so far is mentioned above.........Please help me with this "RANDOM" problem !!

P.S - Will it be possible, by creating a random function in PHP which will check for repeat questions in a session and check for the 'id' of the question and if it is new display it on the page.

If so what should I do and if no then how to do?
