PHP - Sql Query - Multiple Columns
Hi there,
This is what I need to do, blow that is the code I have knocked up to do it but it doesn't seem to work. The main problem is the query that matches the atc callsigns to the pilots destinations.. can't fathom it myself. 1. Pull all the records from my database. 2. Assign their unique user id's, callsigns and destinations. 3. Execute a query in which you: SELECT * FROM CLIENTS WHERE (The 'clienttype' = 'ATC') AND match the callsign of the ATC users to the 'planned_destairport' of the 'clienttype' = 'PILOT'. For example if three people are going to Heathrow, then it would return 3 results. 4. Then do a mysql_num_rows of the result. 5. Lastly, execute a query that would update the 'atcarrivals' collumn in the database with the count number using the unique 'cid' as the identifier. All in a loop of course. // Selects all of the ATC Records. $atc_arrivals_selectquery = mysql_query ("SELECT * FROM CLIENTS"); // Starts the loop for fetching the records of the previous query. while($atc_arrivals_row = mysql_fetch_array($atc_arrivals_selectquery)){ // Sets the users cid, planned_destairport and callsign. $atc_cid = $atc_arrivals_row['cid']; $atc_destinations = $atc_arrivals_row['planned_destaiport']; $atc_callysign = $atc_arrivals_row['callsign']; // Searches the database and selects all records where the callsign is LIKE the destination airport. $atc_arrivals_check = mysql_query("SELECT * FROM CLIENTS WHERE clienttype = 'ATC' AND callsign LIKE '%$atc_destinations'"); // Counts previous query results. $atc_arrivals_count = mysql_num_rows($atc_arrivals_check); // Updates the atcarrivals column with the count.. $atc_arrivals_updatequery = mysql_query("UPDATE CLIENTS SET atcarrivals = '$atc_arrivals_count' WHERE cid = '$atc_cid' AND clienttype = 'ATC'"); // End loop. } Concerned columns are these: "cid" - Unique client id. "atcarrivals" - Number of arrivals from count. (This is the problem.) "planned_destairport" - Destination airport of pilot. Usually four letters long. IE. EGLL = Heathrow. Thanks.

The order the notifications are displaying by their ID is: 3 5 2 4 1 when it should be: 5 3 2 4 1 I made a small editing system for my news page, and I need to update three columns within my table "announcements" in the database. I tried a method of updating all of them with one MySQL query instead of using three as it just isn't neat. I've searched several methods via google and I've tried all of them, but just can't seem to get it to work. Is this MySQL query correct? mysql_query("UPDATE announcements SET title = {$title} WHERE id = '$id', content = {$content} WHERE id = '$id', lastmodified = ". date('M-d-Y') ." WHERE id = '$id'"); Hello all, I am trying to learn OOP in PHP so please forgive my ignorance. I seem to be having difficulty inserting data into my database from checkbox items. My database has a column for each each fruit. I would like for each column to be populated with either a one(1) for checked or a zero(0) for not checked. Currently, my attempts have failed. I can either get all checkboxes to insert all zeros or I can get the first column to insert a one(1) while the others as zeros. Is there anybody here that can help me figure out what I am doing wrong and help me to re-work my code so I can get this to work? If anybody can help me using OOP methods that would be fantastic. Thank you all in advance.

Edited September 23, 2020 by ke-jo Hello all! I'm having some issues with a snippet that I found online and have edited to how I want it. Basically the code works at the moment, except if I were to search for 2 or 3 terms, it would search the columns username/action/result/changes for any result that have any of the words rather than results that include both terms, instead of either. I want the query to be like (assuming 2 search terms): Quote username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' AND username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' and not: Quote username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' OR username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%' It needs an AND instead of an OR, but I'm not sure how to go around doing it. Here's the code as it is at the moment: $filter = ($_POST['filter']); $query = "SELECT * FROM activity WHERE"; $searchresult = explode(" ", $filter); foreach ($searchresult as $key => $filter) { $query .= " username LIKE '%$filter%' OR action LIKE '%$filter%' OR result LIKE '%$filter%' OR changes LIKE '%$filter%'"; if ($key != (sizeof($searchresult) - 1)) $query .= " AND "; } $query .= "ORDER BY id DESC"; Sorry if this is a little confusing to understand, hope someone understands what I need. I want to echo out a few subcategories per main category. It should be a maximum of 20 entries per column At this stage I have the following... It echo's the results out in 4 columns and not what I want. Any suggestions? $query = "SELECT adsubcat.name AS subname, adsubcat.linkname AS sublink, adcat.clinkname AS clink FROM adsubcat JOIN adcat ON adcat.id=adsubcat.catid WHERE adsubcat.catid='$catid' ORDER BY adsubcat.name ASC"; $result = mysql_query($query) or die(mysql_error()); while($row = mysql_fetch_array($result)) { $count = 0; print '<table style="text-align:left;margin-left:0px;width:943px;">'."\n"; while ($row = mysql_fetch_assoc($result)){ $gal = '<a href="'.$root.'/'.$row['clink'].'/'.$row['sublink'].'">'.$row['subname'].'</a>'; if ($count == 0){ print '<tr>'; } ++$count; print '<td>'.$gal.'</td>'; if ($count == 4){ $count = 0; print'</tr>'."\n"; } } print'</table>'."\n"; } I have a table called "friends" and 4 columns called: id......friend_1......friend_2.......date I want to retrieve all of the friends of the user that is logged in, so if the table looks like: friend_1.........friend_2 3.........................6 6.........................8 12.......................3 the result if the users id is 3 would be: 6 12 and if the users id was 6 it would be: 3 8 the query I have right now partially works, just note sure how to modify it to get the full result I want. Code: [Select] $get_friends = mysql_query("SELECT * FROM friends WHERE (friend_1='".$session."' OR friend_2='".$session."')"); while($friends = mysql_fetch_array($get_friends)) { print $friends['friend_1']; }with the code above if you use the table I showed above and assumed that $session = 3, the result is: 3 12 but should be: 6 12 hopefully that's pretty straight forward, thanks in advanced. I have this code which works fine. I want to improve it by displaying it into multiple columns. Current output: TITLE 1 JOB1 --------- TITLE 2 JOB 2 --------- ETC... I want it to display like this instead: TITLE 1 | TITLE 2 JOB 1 | JOB 2 Here is my code: $sql = "SELECT * FROM coaches WHERE position = 'Junior Coach'"; $result = mysql_query ($sql); while ($row = mysql_fetch_array($result)){ $id = $row["id"]; $firstname = $row["firstname"]; $lastname = $row["lastname"]; $position = $row["position"]; $image = $row["image"]; ?> <table width="183" border="1"> <tr> <td align="center" height="18"> <?php echo "<img id='image_shadowCoaches' src=" . $image . ">"; ?><br /> <?php echo "<div id='Coaches_Detail'>".$firstname." ".$lastname."</div>" ?> <?php echo "<div id='Coaches_DetailLower'>".$position."</div>" ?> </td> </tr> </table> <?php } ?> Hi I'm trying to find the max value in 3 columns, new_date, reply_date and finalized_date in my table: Code: [Select] $test = safe_query("SELECT MAX(new_date) FROM (SELECT new_date AS new_date FROM ".PREFIX."cup_challenges UNION SELECT reply_date FROM ".PREFIX."cup_challenges UNION SELECT finalized_date FROM ".PREFIX."cup_challenges) AS maxval"); Did some research and have no idea what is wrong/if the above is correct? The page breaks below this code. I have some code that selects one column from mysql table. However when I try to add more it doesn't work.
First the working code....
$query = "SELECT `profile_privacy` FROM `users` WHERE `user_username` = '$username'"; $result = mysql_query($query) or die($query."<br/><br/>".mysql_error()); $profile_privacy = mysql_result($result, 0);And here is where I have added another column.... $query = "SELECT `profile_privacy`, `profile_pictures` FROM `users` WHERE `user_username` = '$username'"; $result = mysql_query($query) or die($query."<br/><br/>".mysql_error()); $profile_privacy = mysql_result($result, 0); $profile_pictures = mysql_result($result, 1);What have I done wrong? Many thanks, I'm wanting to output data into two columns. I've searched for this in a few places. A vast majority of the search results deal with getting data from multiple columns, and the the ones that deal with what I'm looking for don't really have any solutions attached to them. I'm not fully worried about the columns being equal length. The data is broken up into a certain number of rows in a given year. I have about 12 years, probably 6-8 rows per year. I just don't know how to get it into different columns. I don't care if it goes left to right then down or down then left to right. If there has been a solution to that here already, feel free to point me in that direction. Point me in any applicable direction, I'd fine with. I just can't locate anywhere what trigger would cause that. I create a post just now but cannot seem to find it to add to it. Anyhow, I have 2 tables, I need to multiply qty from the one table to the mass from the other to get a total, which I have achieved with this code:
$sql_total_mass = "
SELECT jobs_assembly.assemble_qty, jobs.mass,
(jobs_assembly.assemble_qty * jobs.mass) AS 'sum'
FROM jobs_assembly
LEFT JOIN jobs on jobs_assembly.jobs_id = jobs.id
LEFT JOIN job_names ON jobs.job_names_id = job_names.job_id
WHERE jobs_assembly.assemble_date = '$link_date'
ORDER BY job_names.job_name, jobs.assembly
";
$result_total_mass = mysqli_query($conn, $sql_total_mass);
if (mysqli_num_rows($result_total_mass) > 0) {
while($row_total_mass = mysqli_fetch_assoc($result_total_mass)) {
echo $row_total_mass['sum'].'<br />';
} //while
} //if
Now I need to take all these totals and make a grand total. So basically add all the results from $row_total_mass[‘sum’] together and show it.
I have a search set up to search a table for the text entered in a textbox, I have two columns in the table, one with the first name of people, and the second with their last names, I am wondering how I can search both, so for instance: I type in the search field: Roger Smith in the database it would look like: First_name-----|-----Last_name -------------------|------------------- Roger------------|-------Smith my current query is: Code: [Select] $query = mysql_query("SELECT * FROM users WHERE fname LIKE '%$find%' OR lname LIKE '%$find%'"); But if I type both parts of the name it doesn't return anything. works fine if I just search for "Roger" OR "Smith". 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 ambiguousThese 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 Not sure if this is the right forum, but I have a database that I will need to populate with a large number of rows (2000+). I have written a PHP script that uploads individual entries. Is it possible to use something like a spreadsheet where I can set out the rows/columns as they will appear in the database, and then upload in one go rather than uploading each row individually? Thanks for any observations and/or help. Hi, I need help to check multiple rows for many columns, so that the script won't re-insert a duplicate entry. For eg: $isRowExist=mysql_query("SELECT (field1,field2) from table1 WHERE field1='$f1' AND field2='$f2' "); if(mysql_num_rows($isRowExist)==1) print "already in table1!"; else //proceed to insert into table table1 *BUT I tried this and it says mysql_num_rows expects resource, and this warning only shows when I have multipel columns I want to compare (it works just fine with one column in the WHERE clause above) Please help! Im having problems with this code in my search button script. I get the following error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource Here's the code I use on my search form. Code: [Select] <form method="post" action="srch_all.php"><input type=text name='search' size=15 maxlength=255><br><input type=submit></form> and here's the code I'm using to perform the search query: Code: [Select] if ($search) // perform search only if a string was entered. { mysql_connect($host, $user, $pass) or die ("Problem connecting to Database"); $srch="%".mysql_real_escape_string($search)."%"; $query = "select * from database WHERE column1 LIKE '$srch' or column2 LIKE '$srch' or column3 LIKE '$srch' or column4 LIKE '$srch' ORDER BY column1, column2 DESC, column3 ASC"; $result = mysql_db_query("database_name", $query); if(mysql_num_rows($result)==0) { print "<h2>Your search returned 0 Results</h2>"; } else if ($result) { <restult data stuff here>.. Cheers Hi There, I have an SQL query that returns 10 rows, which I want to echo over 2 columns and 5 rows, however, I want rows 1-5 on the left hand column and rows 6-10 on the right hand side. Is there an easy way to do this? Normally I would do a fetch_array but, that would place the rows in order of, left, right, left, right - if that makes sense? Table is a standard table with 2 columns and 5 rows. Thanks Matt Well I have a script file that was originally written like this: Code: [Select] $query = "UPDATE ".$prefix."users SET nickname='".$nickname."' WHERE username='".$loggedinname."'"; mysql_query($query); $query = "UPDATE ".$prefix."users SET gender='".$gender."' WHERE username='".$loggedinname."'"; mysql_query($query); $query = "UPDATE ".$prefix."users SET color='".$color."' WHERE username='".$loggedinname."'"; mysql_query($query); $query = "UPDATE ".$prefix."users SET profile='".$profile."' WHERE username='".$loggedinname."'"; mysql_query($query); $query = "UPDATE ".$prefix."users SET favpet='".$favpet."' WHERE username='".$loggedinname."'"; mysql_query($query); $query = "UPDATE ".$prefix."users SET about='".$about."' WHERE username='".$loggedinname."'"; mysql_query($query); I tried to simplify it by rewriting the following codes below, but unfortunately it did not work. It wouldnt give any errors, but the columns aint updated at all: Code: [Select] mysql_query("UPDATE ".$prefix."users SET nickname='".$nickname."' , gender='".$gender."' , color='".$color."' , profile='".$profile."' , favpet='".$favpet."' , about='".$about."' , WHERE username='".$loggedinname."'"); Did I make any mistake rewriting the codes? Or is it actually impossible to update six columns using only one mysql_query? Please help... This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=313325.0 |
