PHP - Can Multiple Entries In A Mysql Table Column Cause Server To Crash?
Here is one of those purely conceptual questions, which involves no code. I'm trying to create a select query which among other things, allows a user of a website to search other members who fall within a particular age range. I have a column in the table where the members' information are stored which records their ages. Which brings us to the problem. On any given day, a member's age may increase by one year compared to what it was the previous day, hence the need to update this column periodically. I can't think of any way to automatically update this column on a daily basis. So my solution is to run an initial update query every time a member tries to search other members based on age, which updates the age column for all other members, before running the select query which eventually retrieves the desired age range. This leads to the second problem. Imagine there are thousands of users using the website. At any given instance, there could be hundreds of members, trying to search others based on age. This means hundreds of users will be updating a single column (the age column) in one table at the same time. Is this feasible? Can it cause the server to crash? Or is there really a more reasonable way to do all of this? Thank you all for taking your time to read this. Appreciate any responses.

Thanks for the reply Dear All, I have attached here with a schema, of MySql DB format i am refering to for the topic i need help on. I want to know what is the best way to achieve this problem / task. I have a profile table, and a category table, and a table to map profiles to category. Which allows me to define/add into the category_profile_mapping table, profile ids against a category id. Each category can have anywhere between 2 to 1,00,000 profiles mapped to it. I have another table called sms_out. hence on the site, when i select a category and submit the form value with message, i want to know what is the best way to populate sms_out with MSISDN from the table "Profile" and the message from the form. The list of MSISDN will be based on the category id selected, hence the profile id's will be available in the category_profile_mapping table. I am bad at explaining the problem, however incase you folks need more info do let me know. i shall be glad to provide the same to .. all of you guys who are willing to help me PS: I am asking this question, cuz i want to knw the best solution to achieve this, when there is entries in millions to be done at one form submit.

A have been working with CS-Cart and had so much trouble trying to update product combinations so I searched for help on the data feeds I am using and found that there was a script that would update my products for os-commerce, this has worked out even worse. All I really need is for a script to update one column called amount in a Mysql table by referring to the product_code column, Eg If product_code NS324 is= to 5 ad 5 to the amount column. This sounds simple but I think it might be complex. Here is the Table Generated b\: phpM\Admin 3.4.9 / M\SQL 5.5.20-log SQL quer\: SELECT * FROM `cscart_product_options_inventor\` LIMIT 0, 30 ; Rows: 30 Column1-----------Column2---------------Column3--------------Column4----------Column5-------Column6-------Column7 product_id-----product_code---------combination_hash-----combination-------amount----------temp-----------position --29813--------------NS3455----------- --1447985068-----------738_3059-----------0-----------------N-------------------0 So if I can update the amount column using the product_code would solve all of my problems. So this is what I need to do, I need to add an amount to the amount column related to the product_code NS3455 or update amount or even replace amount it don't matter. Due to the nature of the feeds I receive I cannot use product_id or combination_hash or combination. Please help me do this. Lets see who is the clever one. Thanks for you time Hi all, I have a table... id | Name | Downloads | 01 | tom | 5 02 | thomas | 2 03 | tommy | 15 I need a button in my page whcih on submit would resent the 'downloads' column so all values are set to 0, Is this possible and how if it is? Thanks for any advice Hey all I'm working on an auction website. I've added a new column to the 'Auctions' table, however the 'sell.php' page now does not work with this new column (I've deleted the column and tested again and it works, so that's definitely the cause). The new column can not be in a separate table as it needs to pull 'id' values from the 'Auctions' table for various functions. My question to you is, is there any PHP snippet I can use to tell sell.php to stop reading the 'Auctions' table once it reaches the column I've added? The new column is called 'shipped' if that's of any relevance. Below is some of the PHP I'm working on on the sell.php page. #//Populate arrays $UPLOADED_PICTURES[] = $file; $UPLOADED_PICTURES_SIZE[] = filesize($image_upload_path.session_id()."/".$file); } } } $_SESSION["UPLOADED_PICTURES"] = $UPLOADED_PICTURES; $_SESSION["UPLOADED_PICTURES_SIZE"] = $UPLOADED_PICTURES_SIZE; $_SESSION["GALLERY_UPDATED"]=true; if($sessionVars['SELL_action']=='edit') { $sessionVars["OLD_GALLERYFEE"] = $SETTINGS["picturesgalleryvalue"] * count($UPLOADED_PICTURES); } else { $sessionVars["OLD_GALLERYFEE"] = 0; } } } } $with_reserve = $sessionVars["SELL_with_reserve"]; $reserve_price = $sessionVars["SELL_reserve_price"]; $minimum_bid = $sessionVars["SELL_minimum_bid"]; $duration_hours = $sessionVars["SELL_duration_hours"]; $duration_minutes = $sessionVars["SELL_duration_minutes"]; $pict_url=$sessionVars["SELL_pict_url"]; $imgtype = $sessionVars["SELL_file_uploaded"]; $title = $sessionVars["SELL_title"]; $description = stripslashes($sessionVars["SELL_description"]); $pict_url = $sessionVars["SELL_pict_url"]; $atype = $sessionVars["SELL_atype"]; $adultonly = $sessionVars["SELL_adultonly"]; $TPL_item_value = $item_value = $sessionVars["SELL_item_value"]; $TPL_number_of_bids =$number_of_bids=$sessionVars["SELL_number_of_bids"]; $TPL_bid_value = $bid_value = $sessionVars["SELL_bid_value"]; $iquantity = $sessionVars["SELL_iquantity"]; $buy_now = $sessionVars["SELL_with_buy_now"]; $buy_now_price = $sessionVars["SELL_buy_now_price"]; $duration = $sessionVars["SELL_duration"]; $duration_second = $sessionVars["SELL_duration_second"]; $minimum_users = $sessionVars["SELL_minimum_users"]; $relist = $sessionVars["SELL_relist"]; $increments = $sessionVars["SELL_increments"]; $customincrement = $sessionVars["SELL_customincrement"]; $international = ($sessionVars["SELL_international"])?"on":""; $sellcat = $_SESSION['sellcat']; $private = $sessionVars["SELL_private"]; if($private != 'y') $private = 'n'; $sendemail = $sessionVars["SELL_sendemail"]; $txt = $sessionVars["SELL_txt"]; $num = $sessionVars["SELL_num"]; $buy_now_only = $sessionVars["SELL_buy_now_only"]; and... $auction_id=$sessionVars['SELL_auction_id']; } elseif ($sessionVars["SELL_action"] == "reopen") { $query = "UPDATE BPLA_auctions set title = '".addslashes($sessionVars["SELL_title"])."', starts = '".$a_starts."', starts_second = '".$a_starts_second."', description = '".addslashes($sessionVars["SELL_description"])."', pict_url = '".addslashes($sessionVars["SELL_pict_url"])."', category = ".$sessionVars["SELL_sellcat"].", minimum_bid = '".$sessionVars["SELL_minimum_bid"]."', reserve_price = '".(($sessionVars["SELL_with_reserve"]=="yes")?$sessionVars["SELL_reserve_price"]:"0")."', buy_now = '".(($sessionVars["SELL_with_buy_now"]=="yes")?$sessionVars["SELL_buy_now_price"]:"0")."', bn_only = '".$sessionVars["SELL_buy_now_only"]."', auction_type = '".$sessionVars["SELL_atype"]."', adultonly = '".$sessionVars["SELL_adultonly"]."', duration = '".$sessionVars["SELL_duration"]."', duration_second = '".$sessionVars["SELL_duration_second"]."', minimum_users = ".intval($sessionVars["SELL_minimum_users"]).", increment = ".doubleval($sessionVars["SELL_customincrement"]).", international = '".(($sessionVars["SELL_international"])?"1":"0")."', ends = '".$a_ends."', ends_second = '".$a_ends_second."', photo_uploaded = ".(($sessionVars["SELL_file_uploaded"])?"1":"0").", quantity = ".$sessionVars["SELL_iquantity"].", relist=".intval($sessionVars["SELL_relist"]).", relisted=0, closed='0', private='n', item_value = '".$sessionVars["SELL_item_value"]."', number_of_bids = '".$sessionVars["SELL_number_of_bids"]."', bid_value = '".$sessionVars["SELL_bid_value"]."', suspended='".$SUSPENDED."',"; $query .= "current_bid=0, num_bids=0, WHERE id = '".$sessionVars["SELL_auction_id"]."'"; $backtoclosed=true; if($BPLowbidAuction_TESTMODE == 'yes'){ echo $ERR = $ERR_9999; }else{ $res=mysql_query($query); if (!$res) { MySQLError($query); exit; } $auction_id=$sessionVars['SELL_auction_id']; $sessionVars["SELL_auction_id_old"]=$auction_id; $query = "DELETE FROM BPLA_bids WHERE auction='$auction_id'"; $res = @mysql_query($query); if(!$res) { MySQLError($query); exit; } Thanks in advance for any help and replies! Hey Everyone, I'm creating a site that will show images uploaded for certain days working on a job site. Kind of a day-to-day photo journal for the customer. On the site, the user gets here, sees 3 large images, and a series of thumbnails if more than 3 images exist for that day (works fine). However, underneath that I want to display a 3-4 column setup of "Archived Dates" that provide a link to the images of the other dates. I have this working correctly, but the results are displayed as follows: Date 1: Date 2: Date 3: etc.... I want them to display like this; Day 1 Day 4 Day 2 Day 5 Day 3 Day 6 and so on..... in a 3 column format. Here is the code I have right now just looping through to display these link results, not the rest of the page. I am trying to do it tableless right now, but if that isn't the right way to go, please let me know. Thanks to anyone in advance, Nick $SQLRowe = "SELECT DISTINCT RoweImgDate from tblRowe WHERE RoweImgDate !='" . $_GET['date'] .

I am basically wanting to give my first column a 'NOT NULL AUTO_INCREMENT' and give each row it's own 'id'. The issue I am having is that the script I am using truncates the whole SQL table with a CSV file that is cron'd daily to update data.
I am currently using this script:
<?php $databasehost = "localhost"; $databasename = ""; $databasetable = ""; $databaseusername=""; $databasepassword = ""; $fieldseparator = ","; $lineseparator = "\n"; $enclosedbyquote = '"'; $csvfile = "db-core/feed/csv/csv.csv"; if(!file_exists($csvfile)) { die("File not found. Make sure you specified the correct path."); } try { $pdo = new PDO("mysql:host=$databasehost;dbname=$databasename", $databaseusername, $databasepassword, array( PDO::MYSQL_ATTR_LOCAL_INFILE => true, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION ) ); } catch (PDOException $e) { die("database connection failed: ".$e->getMessage()); } $pdo->exec("TRUNCATE TABLE `$databasetable`"); $affectedRows = $pdo->exec(" LOAD DATA LOCAL INFILE ".$pdo->quote($csvfile)." REPLACE INTO TABLE `$databasetable` FIELDS OPTIONALLY ENCLOSED BY ".$pdo->quote($enclosedbyquote)." TERMINATED BY ".$pdo->quote($fieldseparator)." LINES TERMINATED BY ".$pdo->quote($lineseparator)." IGNORE 1 LINES"); echo "Loaded a total of $affectedRows records from this csv file.\n"; ?>Is it possible to amend this script to ignore my first column and truncate all of the data in the table apart from the first column? I could then give all of the rows in the first column their own ID's any idea how I could do this? I am still very nooby so please go easy on me I have a form where a user can duplicate part of a form like below: I've named the fields with the HTML arrays (ie. "fieldName[]") and came up with this: //--> CONTROLLERS $system_controllers_qty = $_POST['system_controllers_qty']; $system_controllers_make = $_POST['system_controllers_make']; $system_controllers_model = $_POST['system_controllers_model']; $system_controllers_serial_no = $_POST['system_controllers_serial_no']; for ($i = 0; $i < count($system_controllers_qty); $i++) { echo "qty " . clean($system_controllers_qty[$i]) . "<br/>"; echo "make " . clean($system_controllers_make[$i]) . "<br/>"; echo "model " . clean($system_controllers_model[$i]) . "<br/>"; echo "serial_no " . clean($system_controllers_serial_no[$i]) .

Is it possible to make this all into 1 giant query or am I better off doing each query separately? Each section is a different table. have a database with a column of datatype EM (multiple selection, say apples, oranges, grapes) I want to have a form with checkboxes for those values (apples, oranges, grapes etc) so one can select a breakfast basket type that contains for example, oranges and grapes. It would pull from the database those baskets with those selection of fruits (specified in the column 'Fruits', which is a EM datatype column. (I have a multiple selection when entering the values for the column.) Can it be done? Should I make another table with FruitNames? I have a kind of search and react on my site. The user can search for a number in a column as below $search = mysqli_real_escape_string($link, $_POST["query"]); $query = "SELECT * FROM $table[$i] WHERE oemnr LIKE '".$search."%' ORDER BY model";
The code works fine but I want to expand the function to get match for other numbers also. The oemnr column today can be 12345 which shows up if the user type 12.... I want to expand the oemnr column as 12345/03124/34713, numbers separated with / or another character. If the user type 03... or 34... I want to find and show 12345 because it is on the same row and corresponds to the numbers on the same row. Is it possible to do in mysql? In php that kind of operation can be done with the explode function but I don't know how to use with mysql. Edited February 14 by jiggaHello, For starters I'm not sure if what I want to do is possible, but if it is I would like your input. I have a script that will show a number of fields to fill out in a second form based on the number the user puts into the first from. the problem is that only the last one saves into the database and not all of them. Code: [Select] <form auction="index.php" method="post"> System Name: <input type="text" name="systemname"> Number of E-sites: <input type="text" name="events"> Number of Sigs: <input type="text" name="sigs"><br> <input type="reset" name="reset" value="Reset"> <input type="submit" name="start" value="Start"> </form> <form auction="index.php" method="post"> <?php $events = $_POST['events']; $system = $POST['systemname']; if (isset($_POST['start'])) { $num = $_POST['sigs']; $i = 0; While ($i < $num) { echo "Sig ID: <input type=text name=sigid>"; echo "Type: <input type=text name=type>"; echo "Name: <input type=text name=name>"; echo "Notes: <input type=text name=notes>"; echo "<br>"; $i++; } } ?> <input type="submit" name="enter" value="Enter"> </form> <?php $sigid = $_POST['sigid']; $type = $_POST['type']; $name = $_POST['name']; $notes = $_POST['notes']; mysql_connect('xt', 'x', 'x'); mysql_select_db('wormhole'); if (isset($_POST['enter'])) { $query = "INSERT INTO sites VALUES ('$system','$events','$sigid','$type','$name','$notes')"; mysql_query($query); } ?> How do I get it so all the data saves, lets say that $num = 5, I want all 5 to save not just the last one.

I'm a noob trying to reverse engineer code. I have a script that can retrieve values from a MySQL database (based on a session login that recognizes which user you are) and places those values into the text fields of a form, pre-populating the form. Code: [Select] <?php mysql_connect('localhost', 'db', 'password'); mysql_select_db('users'); $id = mysql_real_escape_string($_SESSION['userid']); $select = "SELECT * FROM user_info WHERE md5(Member_No) = '$id';"; $query = mysql_query($select); if ($row = mysql_fetch_array($query)) { ?> <form> FIRST name: <input type="text" name="First" value="<?php echo stripslashes($row['First']); ?>" LAST name: <input type="text" name="Last" value="<?php echo stripslashes($row['Last']); ?>" > Birthday: <input type="text" name="Birthday" value="<?php echo stripslashes($row['Birthday']); ?>" <input type="submit" value="Submit"> </form> <?php } ?> I want to be able to connect to that same database and update ALL the values (3 in the example above) with the single click of the form button. I think I was told some time ago that it's not possible to update all the values at once? Thanks, ~Wayne Hi, I want to build into my html table that populates my database table to have a column for checkboxes with a delete button that takes the user to another page to confirm the deletion by outputting a message: Are you sure you want to delete ____, followed by a for loop to see how many checked records to get its ID in order to get its appropriate name. So I have a submit button with name attribute of "delete0" and the values of the input type of checkbox is $row['ID'], for some reason, I get the notice: "Notice: Undefined index: modifyArray in C:\display.php" and modifyArray is the name I give to the checkbox attribute (please see this in my display.php below) Here is my display.php Code: [Select] <table border="border"> <!--NB: checkbox form for multiple delete/update/insert--> <form method="post" action=""> <input type='submit' value='DELETE' name='delete0' /> <?php session_start(); require 'bellSessionDisconnect.inc'; require 'bellConnect.inc.php'; $result=mysql_query("SELECT ID, Image, Name, Manufacturer, Price, Description, SimSupport FROM bellProducts"); //phpinfo(); //NB: print table headings if(mysql_num_rows($result))//if there is at least one entry in bellProducts, make a table { //$counter+=1; print "<table border='border'>"; print "<tr> <th>ID</th> <th>Select entries to modifiy</th> <th>Image</th> <th>Name</th> <th>Manufacturer</th> <th>Price</th> <th>Description</th> <th>SimSupport</th> <th colspan='2' align='center'>Modify</th> </tr>"; //NB: now output each row of records while($row=mysql_fetch_assoc($result)) { //extract($row); "<tr align='center'> <td>$row[ID]</td> <td><input type='checkbox' name='modifyArray[]' value='$row[ID]' /></td> <td>"; if(!empty($row['Image'])) { $curImage=$row['Image']; } else if(empty($row['Image'])) { $curImage='fileUploadIcon.jpg'; //$title="please upload item image"; } print "<img src=$curImage width='70px' height='90px' /> </td> <td> $row[Name] </td> <td> $row[Manufacturer] </td> <td> $$row[Price]</td> <td align='left'>$row[Description]</td> <td>$row[SimSupport]</td> <td><a href='bellUploadForm.php?ID=$row[ID]'>UPLOAD IMAGE</a></td> <td><a href='bellUpdateForm.php?ID=$row[ID]'>UPDATE</a></td> </tr>"; //}//END INNER IF }//END WHILE }//END BIG IF ?> <?php if(array_key_exists('delete0', $_POST)) { $modifyArray=$_POST["modifyArray"]; if(!empty($modifyArray)) { header("Location: http://localhost/bellDeleteForm.php"); exit(); } } ?> </form> </table> I will worry about redirecting to bellDeleteForm.php to confirm the records the user wants to delete after I get this going, please help!!! thanks |
