PHP :: Combining Results From MSQL Query

Combining Results 2 Queries
I'm writing an application that allows users to book seats for a ride at 10 different times. I have created 2 queries so far:

1. returns all available seats for that day (at all the times combined). The times table holds a list of ride times. BookingDetails table stores booked seat numbers, show time and other booking details customers have already made. The Place table stores all available seat numbers. To find the times that are not booked I write the following Query but it returns the times that havent been booked at all, if one person books at one time, it shows that time unavailable when infact there are still lots of seats available!

$query="SELECT Time FROM Times, BookingDetails, Place WHERE Times.TimeID != BookingDetails.TimeID";

2. returns all available seats during that day

$query2="SELECT PlaceID, SeatNo FROM Place, BookingDetails WHERE Place.PlaceID != BookingDetails.PlaceID AND PlaceID = Ƈ' ";

In my application the user will first select the time of day they want to book for..ie 10am or 12pm etc. This pulldown menu box will only display times if there are seats avaialble, if there aren't then it won't appear in the list.

After the uer submits the time they want, it will then display current seats available at that time in a table. If the seat is available a check box will be available in a table cell, if it's not then it won't appear and the table cell will be greyed-out. This prevents double booking as there won't be the option to.

From the 2 queries above, what's the best way to get the results I need? Do I just need to combine the 2 queries? I don't think Union will work, I thought about creating a VIEW with the results of both queries and then querying the VIEW? Am I on the right track?

Combining Multiple Queries To Make One Simple Query.
I'm trying to combine 3 queries but having difficulties getting the results I want.

the query is:....

Free PHP + MSQL Host?
Does any know if there is any Free PHP + MSQL Host?

Msql Count Function In A Php Form
I want to show the numebr of rows listed in a specific table. The number needs to be visable each time the page loads automatically.

The table is called registered
The db is called circusart

Getting Too Many Results From A Query!
This is very peculiar -- for some reason, I'm getting 6-8 results from each
of these queries, although only one listing matches. I have a pair of forms
on one page:

<FORM>
Search for lastname: ____________ [Submit]
</FORM>
<FORM>
Search for email: ________________ [Submit]
</FORM>

This goes to a searchresults.php page:

if ($searchname !== "") {
$query="SELECT artistID,firstname,lastname,email,city,state,count ry
from artists WHERE lastname='$searchname'";
$result=mysql_query($query) or die(mysql_error("Could not execute
query."));
while($row = mysql_fetch_array($result)) {
$alt_artistID = $row['artistID'];
$alt_firstname = $row['firstname'];
$alt_lastname= $row['lastname'];
$alt_email = $row['email'];
$alt_city = $row['city'];
$alt_state = $row['state'];
$alt_country = $row['country'];
echo "<CENTER><HR>".$alt_artistID."<BR>"
.$alt_firstname." ".$alt_lastname."</A><BR>"
.$alt_email."<BR>"
.$alt_city.", ".$alt_state." ".$alt_country."<BR>
<A HREF=delete.php?aritstID=".$alt_artistID.">DELETE THIS
LISTING?</A><BR></CENTER>";
}
}

The second section is identical except for:
if ($searchemail !== "") {
$query="SELECT artistID,firstname,lastname,email,city,state,count ry
from artists WHERE email='$searchemail'";
etc...
}

I don't understand why I would get 6-8 records when you can look at them and
see that all but one clearly do not match...?

Using Query Results
Can you use a queries results only once? In this script I'm looping through a query and saving some values in an array. A little further through the script I need to use the same query for output. When I loop through nothing is echo'd to the browser. When I output a row count it shows that the correct number of records, so they must still be there.

Query Results In 2 Columns?
I'm struggling to figure out how to do this properly. I have done a mySQL
query to extract a list of names, and done a mysql_num_rows to determine how
many results I've gotten. I want to split the list in to two columns. I've
created $percol = $mysql_num_rows/2 but I'm not quite sure how to "loop"
through the first half of the list, echo </td><td> and then list the
balance. Can anyone give me some guidance on how best to structure this?

Finding The Results Of A Query
I am working on a script that will query a database for a FNAME/LNAME
combo. If it finds the combo, I need it to do one set of instructions.
If it doesn't find it, I need it to do something else. What I can't
figure out is what variable to check against. Here is what I have for
the relevant part of the script:

$connection = mysql_connect($hostname, $username, $password);
mysql_select_db($databasename) or die ("Cannot connect to database"
..mysql_error());
$query="SELECT FNAME, LNAME FROM (table) WHERE FNAME=('$FName') AND
NAME=('$LName')";
$result = mysql_query($query) or die('Query failed: ' . mysql_error());
mysql_close($connection);

I tried checking the value of $result to see if it changed depending on
whether or not it found the selection. It does not. I just can't figure
out what to use for:

if (some expression){
perform this code
}
else{
do this
}

Grouping Results Of Query
I'm brand new to PHP (just starting today to convert tons of
ColdFusion/Access code to PHP/MySQL). There is a function in
Coldfusion that I can't find an equivalent to in PHP. Here is
what I am trying to do:

If I have a query that results in this information:
State Firstname Lastname
Idaho Terry Pratchet
Vermont Dan Brown
Vermont Bob Smith
Virginia Alice Johnson
Virginia David Jones

I would like to output the info like this:

But all I can find in PHP is a way to loop through the query
and show every row... if you are familiar with Coldfusion,
what I am looking for is something similar to this:

<CFOUTPUT GROUP='State'>
#State#<BR>
<CFOUTPUT>
#Firstname# #Lastname#
</CFOUTPUT>
<BR>
</CFOUTPUT>

Is there a function that does this in PHP, or do I need to
write code that watches the value of 'State' and manually
takes care of things whenever it changes?

ODBC Query Results
Consider the following:

<?

$username = "foo";
$password = "bar";
$host = "db";

$connect = odbc_connect("$host", "$username", "$password") or die;

$query = "SELECT id, name, address, city, state, comments1, comments2
FROM data.table1, data.table2 WHERE id = ô˜'";

$result = odbc_exec($connect, $query);

while(odbc_fetch_row($result)){
$id = odbc_result($result, 1);
$name = odbc_result($result, 2);
$address = odbc_result($result, 3);
$city = odbc_result($result, 4);
$state = odbc_result($result, 5);
$zip = odbc_result($result, 6);
$comments1 = odbc_result($result, 7);
$comments2 = odbc_result($result, 8);
print("ID: $id<br>Name: $name<br>Address: $address<br>City:
$city<br>State: $state<br>Zip: $zip<br>Comments1:
$comments1<br>Comments2: $comments2<br>
");

}
?>

Only one record is returned from data.table1 (containing the id, name,
address, city, state, & zip). However, there are multiple records
returned from data.table2 (records from comments1 & comments2). What
is happening is that when I run this script, all of the data returned
from data.table1 is printed over & over again along with each record
returned from data.table2. How can I make it such that id, name,
address, city, state & zip are only printed once - and allow comments1
& comments2 to be printed multiple times for each occurance in the
database?

I've thought about just creating a second database query for the
records in data.table2, however I need the join I'm getting by using
the existing query.

For what it's worth, I'm connecting to a DB2 database using PHP /
Apache on Linux.

I'm confused by this.

Losing Query Results!
If I make a query;

$result = mysql_query($theQuery, $db);

and then make use of the query results like so;

while ($row = mysql_fetch_row($result)) {

//do something with query results}

I can't use $result again, I have to make another query! Why is this and is there any way around it?

Multiple Sql Query Results
I'm trying to do a query from 2 databases. Basically i have
catagories within 2 databases. If both catagories return 0 rows then it
does nothing but if one or both have rows returned then i need it to
echo a result. I guess where i'm wondering if there's an OR statement i
can use or something to that effect...

something like

if($numrows == 0 OR $numrows2 == 0) {
echo ('');
}else{
echo ('$result');

SQL Query - Results From Another PHP Page ?
Can I store this PHP code in another page, then refernece it on
multiple pages using Require or Include ???

//results from sql query
for ($i=0; $i<$number; $i++) {
$ID = mysql_result($result,$i,"ID");
$CompanyName = mysql_result($result,$i,"1");
$ContactName = mysql_result($result,$i,"2");
$Phone = mysql_result($result,$i,"3");
$HomePhone = mysql_result($result,$i,"4");
$MobilePhone = mysql_result($result,$i,"5");
$AltPhone = mysql_result($result,$i,"6");
$SecondContact = mysql_result($result,$i,"7");
$SecondPhone = mysql_result($result,$i,"8");
$ThirdContact = mysql_result($result,$i,"9");
$ThirdPhone = mysql_result($result,$i,"10");
$Notes = mysql_result($result,$i,"11")

Sql Query Results And Scrolling
I make a mySQL database query and display the first 10 results. Then
the user can click on "next" link to get the next 10 results. How can
I do that without issuing the sql query again? Can I keep the results
from the first query?

Query In PHP Won't Return Results In There's Only 1
$sql = 'SELECT `PageTitle` '
$sql .= 'FROM `Pages` '
$sql .= 'WHERE `PageID` = 1 LIMIT 0, 30'

I have run this query in MySQL control panel and it works perfectly.
When I try to do it via PHP I get no results.

If I select all rows (i.e I don't specify a "WHERE") I get one fewer
rows returned than there actually are.

Tabulating Sql Query Results
I'm trying to number my rows in the column named "Pos" but so far I not getting any success, someone please bail me out find below my script, this script displays my results fine but without my Positions (Pos); Code:

Filtering Results With Php Query
This code works, but I don't know how to filter the results to where only one person is displayed..it displays all records with similar address or state or city, I would like to know how to make it display only one person when multiple search fields are entered.

I'm using PHP5, and I have searched the forums but I'm not sure exactly if I found what I'm looking for...I don't know much about php or mysql. Code:

Capturing/using Results Of Query
I would like to display/capture/use the URL's that are displayed on a web page after making a query to a forum.
What do I mean?

I am part of a forum that uses vBulletin. One option is to display the forum topics that have had posts that day, i.e. active topics.

Essentially, when you click on the link:
http://www.somedomain.com/forum/search.php?do=getdaily

the resultant page has a list of the active topics, highlighted as links.

What i would like to do is capture/access that resultant page and use regular expressions to grab the URLs. I can do the RegEx but I cannot seem to capture that resultant page.

How Do I Show Results Of A Query
I know how to connect to a Mysql table. I want to run the query and show the results on my page. I'll have about 25 different fields I need to show on the page. Most of this information will be a couple of addresses.

Basically, a billing and then a shipping address. Can someone show me how to show some of this on a page? I'll need to align all this stuff around the page.

Filter Results Of Query
I am modifying some pages in CRE Loaded.

allprods.php list all currently active products and I added a manufacturers column that displays who makes that product.

I want to allow shoppers to filter the product list so that it shows only products from a particular manufacturer.

I have gone through several scenarios in my mind, but nothing I've thought of seems simple and bullet proof.

One of the issues is that the all products query includes all manufacturers. If I were to put a variable in the query to select only a particular manufacturer, how would I code it so it does not interfere with the all products query?

Would logic based upon the value of a form action work? If form action exists, someone wants to filter. If not form action or form action = all, then they want the whole list. Seems like filtering a list is pretty common and there should be an easy solution.

Formatting Problem With Query Results
I have a minor problem with a script. I have written a piece of code (do...while loop) that will return results of a query a row at a time, with the proper formatting in a table. Everything works fine when there are results to lay out in the table. The problem arises when the query yields no results. When this happens, the loop below iterates once (without data) instead of not executing at all:

$result2=mysql_query("select * from ...) or die("");
$myrow2=mysql_fetch_array($result2);

do {

...bunch of stuff...

}

while($myrow2 = mysql_fetch_array($result2));

Where do we go from here?

Sorting Database Query Results
I want to know if it is possible to sort query results so that the records with a value in a certain field is displayed first and the records with the field empty thereafter.

Sorting Query Results Into Groups
I have a 'staff' table with a column 'status', corresponding to a
'statuses' table with the appropriate titles (eg 1 | Editor in Chief).
I want to display on the page the headings (the titles from statuses)
along with all of the staff members with that status ID.

I've attempted this using a query for each possible status, which I
figure was pretty inefficient (plus it didn't work properly). The best
I could do manually was to just display a list of staff and their
statuses sorted in order of the title ranks.

How To LIMIT Results In Html Php/sql Query?
I need to limit results in the following query type:

http://www.somewhere.com/php/sql-a....ql_order=&pos=1

I found a reference that says I should be able to use LIMIT x[,y], but
I don't know where/exactly how to add that to the string. Once I know
what it's supposed to look like, and can write something to generate
it.

If someone could post an example using the above and limiting the
output to 100 records starting at position.

Display Query Results In A Table
$sql = "SELECT name FROM employee_tb;
$result_query = @mysql_query ($sql);// run the query
while ($row = mysql_fetch_array($result_query,MYSQL_NUM)){
$name = $row[0];}
// assuming i have 8 results

how can i display the results from this query in a table with 3 rows each column?

Query Results And Affected Rows?
I'm doing a mass database update and I have a query string something like this:

UPDATE table SET field1=0, field2='' WHERE (email='address1' OR email='address2' {and so on...} );

I know you can view how many rows were changed after its done. I'm wondering though, is there a way I can view which entries failed? For example, lets say the email address - 'address34' was not found in the database, is there anyway I can display this from this UPDATE query? or to do this, would I have to compare each address individually with the table to check if it exists? (and if it matters I have about 1000 adresses that are being updated from this)

Query Results With Multiple Keywords
The way I have it set up now, a form results in 2 keywords, namely Keyword and Keyword2 using 1 text field, and one select field. In the text field, the person enters in the City, in the Select field, they choose a state, which abbreviates it to 2 letters.
Now, for the code that is supposed to process this: Code:

Exploding Results Of Mysql Query
I have a table with times and dates listed like this:

0000-00-00 00:00:00
2003-09-20 20:26:22
etc
etc

What I want is to query the DB for the field (matchdate) and then get it to explode the ' ' to give jsut the date for me and then put it into a dropdown in a loop. this may sound easy but i too sleepy to work it out and searching aint good.

Sql Query Not Returning Correct Results
i'm using an entry in an sql database as a semaphore and it,
unfortunately, doesn't appear to be working. the script that spawns
the child processes has a for loop that performs the same basic sql
query over and over again until the value has changed (there's a one
second delay between each query). unfortunately, the resultant row is
always the same, even when the other process *has* changed it. as an
example, if the orig. value was of the entry was 0, and one second into
the execution of the second process, the entry was changed to 1, my
program would, even 10 seconds later, fetch 0. in other words, it'd
never be aware of the change.

any idea as to why this is and what i can do to fix it?

Aligning Multiple Query Results
I'm trying to pull data from 2 different tables and do a loop to
retrieve more than one row. I'm having problems with aligning the
information. Can someone lead me in the right direction? I've done some
looking myself and found something called GROUP BY? Is that what I need
to use?

Checking Lenth Of Query Results
If I return a result from a query with mysql_fetch_array and need to check the character length of a specific field, what is the best way? I have tried mysql_field_len but am getting errors with the code below: PHP Code:

Arrays, Query Results And Select Box
I want/need to pre-select a drop-down box with a value if it's present in both a lookup table and user account table. After wrestling with this for a few hours I give up.

i know this can't be this complicated, but apparently i'm missing something, so if anyone can suggest a way to go about this i'd be a little more sane. The idea is to have the user value already selected then when they change the value i'll update their account.

I Need To Export Query Results To A .txt File.
Here's some code:

I need this info displayed on a .txt file that is updated each time that text file is called up. So if a new result is added, when that text file is called up I need that new listing to appear there. Or every time a new result is added, it updates the text file. Whichever makes the most sense, I'm not sure.

How To Truncate Multiple Query Results....
I have a news section on my website, where the article(s) are stored in a MySQL database. Titles in one column, article body in another. On the actual page, I have a limited space to which to print the content, and need to truncate it so it does not overlap, or stretch the content div and blow the design out of whack.

When only returning one article from the db, I can do this easily, however, the problem is that not all articles are/will be lengthy enough to fill the div. In such cases, I want to return the next article, up to the remaining div space, then truncate it.

For example, right now, the article that's being displayed fills up more than the allotted space, so it's truncated. But the next three articles I post may be short, where I'd need all three plus a segment of a fourth to fill the space. Using Dreamweaver MX2k4 I can do this by "repeating that region", but limiting the number of characters is only applicable to each query, not to the overall div. As such, it won't work in the way I need. Code:

MySQL Query Not Returning All Results
I have a user table in the DB, for example:

+---------+----------------+-------------------+
| uid | username | firstname |
|----------+----------------+------------------+
| 1 | cobby | Andrew |
| 2 | admini | test-account |
+---------+-----------------+------------------+

If, in phpMyAdmin, I query:
SELECT `username` FROM `users`;

It will return results correctly (cobby and admini, respectively).
But if I make a simple PHP script, such as:

<?php

mysql_connect('localhost', 'cobby', 'dbpass');
mysql_select_db('testdb');

$query = mysql_query('SELECT `username` FROM `users`');
print_r(mysql_fetch_assoc($query));

?>

It only returns:
Array ( [username] => admini )

Why does it only return the second result? I have a feeling I'm doing something really silly, but I looked over this test script and its got me stumped.

Using Arrays With Mysql Query Results
im currently in the process of making a piece of code that will firstly take all the data from a table in mysql and then assign it to an array. This data will consist of several different rows of data each with different infomation for each field in the table.

i want to be able to use an array in a loop so that depending on which number of the loop is on will change the infomation that is assigned to a certain array. Code:

I Get The Number Of Raws From A Query, But Can't See Results
I get the number of raws from a query, but can't see results?

Putting A Line Break In Query Results
Quick question, how would you go about putting a line break after a certain number of results pulled from a query? What happens is I get too many results and it stretches the page, thus looking awful. So what I want to do is print half of the results on one line, use a line break <br /> and display the other half.

So instead of results that are say....
A B C D E F G H I J K L M N O P Q R S

I want....
A B C D E F G H I J
K L M N O P Q R S

Display Results From Query In HTML-table
I'm working with PHP3 and Oracle 8. Can anyone tell me how to display the results from a query into my HTML-table?

Possible To Create A Variable From The Results Of A Mysql Query?
I need to perform a mysql query,Take the results and create a loop for each item that returns, and then create a variable that will pull the complete results from the query to include into a template. here is the code I am woring with PHP Code:

Caching MySQL Search Query & Results
I'm developing a site that may eventually have a very large database of
users (hopefully, but who knows). It will be a community website where
users can search each other (think Friendster, Classmates, every dating site
out there, etc.).

Often there will be queries with multiple joins and sometimes may include a
few fulltext searches. Each page of results will have a limited number of
results displayed (obviously). As I understand it, MySQL caches only exact
queries, so doing a LIMIT (x,y) on each query to get results for the
specific page will cause MySQL to run the entire query again, instead of
pulling from the cache. I will limit the results to 1000, but what's the
best way to limit results per page?

I was thinking that I could run the SELECT and LIMIT to 1000, then do a
mysql_data_seek to jump to the starting row for the page and fetch a certain
number of rows for the page. For each page, the exact same SELECT would be
used and therefore the results would be cached.

Also, how should I save the search query? The users will be searching with
any number of search terms, way too many to do use GET variables. I don't
want to create a hidden form with each search term as hidden inputs (for
one, that's kind of lame). I was thinking of saving the search query to the
database, I guess I could implode the POST array into a string and then save
it in the db.

Output Query Results To Html Table
I have a MySQL table "products" and I want to output product's data to html table as below:

- 4 products is nested in 1 html table 4 rows x 4 columns.

Detecting Whether Or Not A Query Has Results (if Statement Problems)
this is the situation. a person comes to a login page, with a form. they type in their password and username. the form sends it to another page, which tests the username and password against the records in my mySQL database. i want to do an if statement where if their username/password match, then they do so and so (write a cookie, display text saying hi, so on so forth)

BUT, if their username/password does NOT match, it gives back a message saying they are not logged in, etc etc... i can get it to do the log in part correctly, just fine. but how do i detect an incorrect match in the database. here is what i have: Code:

Mysql Doesnt Return All Results Of A Query
I have an sql query like this:
SELECT column FROM table WHERE column1="3" AND column2="1"
This query works perfectly if i run it in the command line, to be
exactly it return two results.
But if i run it from php i just get the first of the two results.
Any ideas?

Mysql 4.1.8
php 5.0.3

I have a second problem. But its more of a question.
if i run the foreach loop on an array like this
array("id" => "78"), then it splits 78 up in 7 and 8.
Now you say its stupid to use a foreach for this array. But in the
function there i use it the array could also be two dimensional.
Is this behavior normal? I looked in the php manual but found nothing.

Show Mysql Query Results On Pages
Does anyone have a script that will show mysql query results as paged results? This is what I have at the moment and it does not pass the results to the second page. Code:

Weird Query Results / <title> Issues
I'm editing some stuff I did last summer, trying to bugfix and improve
stuff. One improvement (or an oversight of the original design) is
adding dynamic <title> tags to my pages. Here's how I originally
structured my php pages:

include header.php (contents are basically my HTML/CSS up to the
 point)
<php code>
include footer.php (contents are from  onwards).

Obviously this meant I had the same <title> as defined in header.php
for every page, not cool. I went through and revised the structure to
this:

include doctype.php (HTML from the opening document declaration down to
just before <title>)
Then began my query(s), and once the results were grabbed:
echo "<title>$bandName - recordName review</title";
include header.php (this file now contains everything below <title>
down to )
<php code to output content>
include footer.php (as above)

This worked great for almost all of my pages but one. Here's the link:

This might look normal to you, but try clicking some of the other
reviews in the left panel. The cover image and headings stay the same,
and the author information at the bottom again stays the same, which is
of course incorrect. I'm not sure where I'm going wrong with my code,
so I'll post up what I'm doing:

That file has doctype.php, header.php and footer.php physically
included so you can see their contents too (ordinarily they're included
with php includes).

Adding Values In One Column From Query Results
I have this query:

SELECT *,
sum(field_value) as totalValue
FROM table_name
WHERE field_id = $id
GROUP BY field_group

the data type of field value is a decimal value, with values such as 125.00 and 150.50 stored in each record. My goal is to have totalValue be the total value of those numbers. So if I have two records that equal 125.00 and 150.50 totalValue would = 175.50.

the above query does not do this. What do I need to change here? Should I try to do this from the PHP side?
