  • Facebook Page Statuses API

    - by Simon R
    I've got a curl function in php which posts a status update to our facebook page. However, when I post the update it makes the status appear from me personally rather than me the group. Does anyone know how you can post as administrator of the group. The script is as follows; $xPost['access_token'] = "[key]" $xPost['message'] = "Posting a message test."; $query = http_build_query($xPost); $ch = curl_init('https://graph.facebook.com/broadland/feed'); curl_setopt($ch, CURLOPT_VERBOSE, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 120); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $query); curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_CAINFO, NULL); curl_setopt($ch, CURLOPT_CAPATH, NULL); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); $result = curl_exec($ch);

  • JBoss database connection pool configuration

    - by Qben
    I am facing an connection pool issue in my clustered JBoss installation. From time to time one of my connection pools will hit the roof and I get a lot of these in my logfile. java.sql.SQLException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); The odd thing is that I can see in the JMX console that the ConnectionCount hit the roof, but at the same time InUseConnectionCount is often quite small. The problem will resolve itself after a couple of minutes but during recovery phase my application will not work (for obvious reasons). The question is if this indicate an error in the configured timeouts of the connections (I pretty much use defaults), or if my pool is simply too small to handle the peaks. Under normal operation I would say I use ~40% of the configured max number of connections. The reason I just don't increase the max number of connection is that if I actually used up all connections I suspect that InUseConnectionCount would hit the roof. Hence I suspect I might have more issues than just a too small pool size. Maybe InUseConnectionCount has decreased at the time I check jmx-console and it actually do hit the roof? I tend to collect data every second minute. Any hints are more than welcome.

  • Recommended approach for error handling with PHP and MYSQL

    - by iama
    I am trying to capture database (MYSQL) errors in my PHP web application. Currently, I see that there are functions like mysqli_error(), mysqli_errno() for capturing the last occurred error. However, this still requires me to check for error occurrence using repeated if/else statements in my php code. You may check my code below to see what I mean. Is there a better approach to doing this? (or) Should I write my own code to raise exceptions and catch them in one single place? What is the recommended approach? Also, does PDO raise exceptions? Thanks. function db_userexists($name, $pwd, &$dbErr) { $bUserExists = false; $uid = 0; $dbErr = ''; $db = new mysqli(SERVER, USER, PASSWORD, DB); if (!mysqli_connect_errno()) { $query = "select uid from user where uname = ? and pwd = ?"; $stmt = $db->prepare($query); if ($stmt) { if ($stmt->bind_param("ss", $name, $pwd)) { if ($stmt->bind_result($uid)) { if ($stmt->execute()) { if ($stmt->fetch()) { if ($uid) $bUserExists = true; } } } } if (!$bUserExists) $dbErr = $db->error(); $stmt->close(); } if (!$bUserExists) $dbErr = $db->error(); $db->close(); } else { $dbErr = mysqli_connect_error(); } return $bUserExists; }

  • Why does this sql statement keep saying it is a boolean and not a paramter? (php/Mysql)

    - by ggfan
    In this statement, I am trying to see if there if the latest posting in the database that has the exact same title, price, city, state, detail. If there is, then it would say to the user that the exact post has been already made; if not then insert the posting into the dbc. (This is one type of check so that users can't accidentally post twice. This may not be the best check, but this statement error is annoying me, so I want it to work :)) Why won't this sql work? I think it's not letting the title=$title and not getting the value in the $title... ERROR: mysqli_num_rows() expects parameter 1 to be mysqli_result, boolean given in postad.php on line 365 //there is a form that users fill out that has title, price, city, etc <form> blah blah </form> //if users click submit, then does all the checks and if all okay, insert to dbc if (isset($_POST['submit'])) { // Grab the pposting data from the POST and gets rid of any funny stuff $title = mysqli_real_escape_string($dbc, trim($_POST['title'])); $price = mysqli_real_escape_string($dbc, trim($_POST['price'])); $city = mysqli_real_escape_string($dbc, trim($_POST['city'])); $state = mysqli_real_escape_string($dbc, trim($_POST['state'])); $detail = mysqli_real_escape_string($dbc, trim($_POST['detail'])); if (!is_numeric($price) && !empty($price)) { echo "<p class='error'>The price can only be numbers. No special characters, etc</p>"; } //Error problem...won't let me set title=$title, detail=$detail, etc. //this statement after all the checks so that none of the variables are empty $query="Select * FROM posting WHERE user_id={$_SESSION['user_id']} AND title=$title AND price=$price AND city=$city AND state=$state AND detail=$detail"; $data = mysqli_query($dbc, $query); if(mysqli_num_rows($data)==1) { echo "You already posted this ad. Most likely caused by refreshing too many times."; } }

  • iptables rules to allow HTTP traffic to one domain only

    - by Zenet
    I need to configure my machine as to allow HTTP traffic to/from serverfault.com only. All other websites, services ports are not accessible. I came up with these iptables rules: #drop everything iptables -P INPUT DROP iptables -P OUTPUT DROP #Now, allow connection to website serverfault.com on port 80 iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT #allow loopback iptables -I INPUT 1 -i lo -j ACCEPT It doesn't work quite well: After I drop everything, and move on to rule 3: iptables -A OUTPUT -p tcp -d serverfault.com --dport 80 -j ACCEPT I get this error: iptables v1.4.4: host/network `serverfault.com' not found Try `iptables -h' or 'iptables --help' for more information. Do you think it is related to DNS? Should I allow it as well? Or should I just put IP addresses in the rules? Do you think what I'm trying to do could be achieved with simpler rules? How? I would appreciate any help or hints on this. Thanks a lot!

  • how to find missing rows in oracle

    - by user203212
    Hi, I have a table called 2 tables create table ORDERS ( ORDER_NO NUMBER(38,0) not null, ORDER_DATE DATE not null, SHIP_DATE DATE null, SHIPPING_METHOD VARCHAR2(12) null, TAX_STATUS CHAR(1) null, SUBTOTAL NUMBER null, TAX_AMT NUMBER null, SHIPPING_CHARGE NUMBER null, TOTAL_AMT NUMBER null, CUSTOMER_NO NUMBER(38,0) null, EMPLOYEE_NO NUMBER(38,0) null, BRANCH_NO NUMBER(38,0) null, constraint ORDERS_ORDERNO_PK primary key (ORDER_NO) ); and create table PAYMENTS ( PAYMENT_NO NUMBER(38,0) NOT NULL, CUSTOMER_NO NUMBER(38,0) null, ORDER_NO NUMBER(38,0) null, AMT_PAID NUMBER NULL, PAY_METHOD VARCHAR(10) NULL, DATE_PAID DATE NULL, LATE_DAYS NUMBER NULL, LATE_FEES NUMBER NULL, constraint PAYMENTS_PAYMENTNO_PK primary key (PAYMENT_NO) ); I am trying to find how many late orders each customer have. the column late_days in PAYMENTS table has how many days the customer is late for making payments for any particular order. so I am making this query SELECT C.CUSTOMER_NO, C.lname, C.fname, sysdate, COUNT(P.ORDER_NO) as number_LATE_ORDERS FROM CUSTOMER C, orders o, PAYMENTS P WHERE C.CUSTOMER_NO = o.CUSTOMER_NO AND P.order_no = o.order_no AND P.LATE_DAYS>0 group by C.CUSTOMER_NO, C.lname, C.fname That means, I am counting the orders those have any late payments and late_days0. But this is giving me only the customers who have any orders with late_days0, but the customers who does not have any late orders are not showing up. so if one customer has 5 orders with late payments then it is showing 5 for that customer, but if a customer have 0 late orders,that customer is not selected in this query. Is there any way to select all the customers , and if he has any late orders, it will show the number and also if he does not have any late orders, it will show 0.

  • What's the best way to access a MS Access database using PHP?

    - by Jack Roscoe
    Hi, I need to access some data from an MS Access database and retrieve some data from it using PHP. I've looked around the web, and found the following line which seems to correctly connect to the database: $conn->Open("DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=C:\wamp\www\data\MYDB.mdb"); However, I have tried to retrieve some data in the following way: $query = "SELECT pageid FROM pages_table"; $result = mysqli_query($conn, $query); $amount_of_pages = 0; if(mysqli_num_rows($result) <= 0) echo "No results found."; else while($row = mysqli_fetch_array($result, MYSQL_ASSOC)) $amount_of_pages++; And was presented with the following errors: Warning: mysqli_query() expects parameter 1 to be mysqli, object given in C:\wamp\www\data\index.php on line 19 Warning: mysqli_num_rows() expects parameter 1 to be mysqli_result, null given in C:\wamp\www\data\index.php on line 23 No results found. I don't really understand the connection to the Access database, is there something I should be doing differently? Thanks in advance for any help.

  • How do I iterate through hierarchical data in a Sql Server 2005 stored proc?

    - by AlexChilcott
    Hi, I have a SqlServer2005 table "Group" similar to the following: Id (PK, int) Name (varchar(50)) ParentId (int) where ParentId refers to another Id in the Group table. This is used to model hierarchical groups such as: Group 1 (id = 1, parentid = null) +--Group 2 (id = 2, parentid = 1) +--Group 3 (id = 3, parentid = 1) +--Group 4 (id = 4, parentid = 3) Group 5 (id = 5, parentid = null) +--Group 6 (id = 6, parentid = 5) You get the picture I have another table, let's call it "Data" for the sake of simplification, which looks something like: Id (PK, int) Key (varchar) Value (varchar) GroupId (FK, int) Now, I am trying to write a stored proc which can get me the "Data" for a given group. For example, if I query for group 1, it returns me the Key-Value-Pairs from Data where groupId = 1. If I query for group 2, it returns the KVPs for groupId = 1, then unioned with those which have groupId = 2 (and duplicated keys are replaced). Ideally, the sproc would also fail gracefully if there is a cycle (ie if group 1's parent is group 2 and group 2's parent is group 1) Has anyone had experience in writing such a sproc, or know how this might be accomplished? Thanks guys, much appreciated, Alex

  • nextgen gallery order issue

    - by mro
    Hi, wonder if anyone can help. I think what I'm after won't be solved by any exsiting code in nextgen plugin (in wordpress) due to the custom way I'm using it hence I come to stackoverflow for some opnions. Bascially - I am only really using the admin of nextgen to work with the gallerys etc. The actual meat of the functionality I'm querying the nextgen DB's direct from my code, I would have loved to use the inbuilt gallerys in nextgen, but my spec specifics were so custom I couldn't. My issue is, I need to pull the images from the DB's in the order it is in the admin (ie if a user pulls the sort order around in the drag and drop area). I have noticed however this doesn't affect the image id order in the DB, and wouldn't expect it to - that would be some complex shifting around just to reorder everytime surely. So obviously when I query the DB the order it's looking at is when it was created, by image id, with my filtering on top. I'm wondering though if there is a way I can query that sort order that's determined in the admin somehow, then at least I could sort the array somehow in the code ? does next gen store it's user custom sort order somewhere ? Hope this makes sense :) any thoughts appreciated. Thanks

  • servlet connection to DB

    - by underW
    Initially, after reading books on the subject, I firmly believed that the algorithm for working with a database from a servlet is as follows: create a connection - connect to the database - form a request - send the request to the database - get the query results - process them - close connection - OK. Now, with a better understanding of the practical side, I realized that nobody does it that way, and everything happens through a connection pool according to the following algorithm: initialize the servlet - create a connection pool - a request comes from a user - take a free connection from the pool - form a request - send the request to the database - get the query results - process them - return the connection back to the pool - ok. Now I have this problem: We have 100 users, they are divided into 10 groups, each group has it's own username and password to connect to the database. Moreover, each group may have different rights to the database. How am I supposed to use a connection pool in this situation? If I understand correctly, a pool is nothing more than just a group of similar connections with a single login and password. And here I have 10 pairs of username / password. It looks like I cannot use the pool in this situation. What should I do?

  • Fixing an SQL where statement that is ugly and confusing

    - by Mike Wills
    I am directly querying the back-end MS SQL Server for a software package. The key field (vehicle number) is defined as alpha though we are entering numeric value in the field. There is only one exception to this, we place an "R" before the number when the vehicle is being retired (which means we sold it or the vehicle is junked). Assuming the users do this right, we should not run into a problem using this method. (Right or wrong isn't the issue here) Fast forward to now. I am trying to query a subset of these vehicle numbers (800 - 899) for some special processing. By doing a range of '800' to '899' we also get 80, 81, etc. If I cast the vehicle number into an INT, I should be able to get the right range. Except that these "R" vehicles are kicking me in the butt now. I have tried where vehicleId not like 'R%' and cast(vehicleId as int) between 800 and 899 however, I get a casting error on one of these "R" vehicles. What does work is where vehicleId not between '800' and '899' and cast(vehicleId as int) between 800 and 899', but I feel there has to be a better way and less confusing way. I have also tried other variations with HAVING and a sub-query all producing a casting error.

    I'm a PHP beginner and lately i've been having a problem with my source code. Here it is: <html> <head> <title> Bot </title> <link type="text/css" rel="stylesheet" href="main.css" /> </head> <body> <form action="bot.php "method="post"> <lable>You:<input type="text" name="intrebare"></lable> <input type="submit" name="introdu" value="Send"> </form> </body> </html> <?php //error_reporting(E_ALL & ~E_NOTICE); mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("robo") or die(mysql_error()); $intrebare=$_POST['intrebare']; $query = "SELECT * FROM dialog where intrebare like '%$intrebare%'"; $result = mysql_query($query) or die(mysql_error()); $row = mysql_fetch_array($result) or die(mysql_error()); ?> <div id="history"> <?php foreach($row as $rows){ echo "<b>The robot says: </b><br />"; echo $row['raspuns']; } ?> </div> It returns me the result x6 times. This problem appeared when I've made that foreach because I wanted the results to stuck on the page one by one after every sql querry. Can you please tell me what seems to be the problem? Thanks!

  • Programming logic best practice - redundant checks

    - by eldblz
    I'm creating a large PHP project and I've a trivial doubt about how to proceed. Assume we got a class books, in this class I've the method ReturnInfo: function ReturnInfo($id) { if( is_numeric($id) ) { $query = "SELECT * FROM books WHERE id='" . $id . "' LIMIT 1;"; if( $row = $this->DBDrive->ExecuteQuery($query, $FetchResults=TRUE) ) { return $row; } else { return FALSE; } } else { throw new Exception('Books - ReturnInfo - id not valid.'); } } Then i have another method PrintInfo function PrintInfo($id) { print_r( $this->ReturnInfo($id) ); } Obviously the code sample are just for example and not actual production code. In the second method should I check (again) if id is numeric ? Or can I skip it because is already taken care in the first method and if it's not an exception will be thrown? Till now I always wrote code with redundant checks (no matter if already checked elsewhere i'll check it also here) Is there a best practice? Is just common sense? Thank you in advance for your kind replies.

  • Paging using Linq-To-Sql based on two parameters in asp.net mvc...

    - by Pandiya Chendur
    As two parameters i say currentPage and pagesize .....I thus far used sql server stored procedures and implemented paging like this, GO ALTER PROCEDURE [dbo].[GetMaterialsInView] -- Add the parameters for the stored procedure here @CurrentPage INT, @PageSize INT AS BEGIN -- SET NOCOUNT ON added to prevent extra result sets from -- interfering with SELECT statements. SET NOCOUNT ON; SELECT *,ROW_NUMBER() OVER (ORDER BY Id) AS Row FROM ( SELECT *,ROW_NUMBER() OVER (ORDER BY Id) AS Row FROM InTimePagingView ) AS InTimePages WHERE Row >= (@CurrentPage - 1) * @PageSize + 1 AND Row <= @CurrentPage*@PageSize SELECT COUNT(*) as TotalCount FROM InTimePagingView SELECT CEILING(COUNT(*) / CAST(@PageSize AS FLOAT)) NumberOfPages FROM InTimePagingView END Now i am using Linq-to-sql and i use this, public IQueryable<MaterialsObj> FindAllMaterials() { var materials = from m in db.Materials join Mt in db.MeasurementTypes on m.MeasurementTypeId equals Mt.Id where m.Is_Deleted == 0 select new MaterialsObj() { Id = Convert.ToInt64(m.Mat_id), Mat_Name = m.Mat_Name, Mes_Name = Mt.Name, }; return materials; } Now i want to return the records,TotalCount where i use Total count to generate pagenumbers..... Is this possible... Any suggestion... EDIT: Just found this... NorthWindDataContext db = new NorthWindDataContext(); var query = from c in db.Customers select c.CompanyName; //Assuming Page Number = 2, Page Size = 10 int iPageNum = 2; int iPageSize = 10; var PagedData = query.Skip((iPageNum - 1) * iPageSize).Take(iPageSize); ObjectDumper.Write(PagedData);

  • Pass variable to Info Window in FusionTableLayer

    - by user1030205
    I am building a web application that includes a Google Map layered with data from a Google Fusion Table. I have defined the info window for the markers in the Fusion Table and all is rendering as expected, but I have one issue. I need to pass a session variable from my web application to be included in the links that are defined in the info window, but can't seem to find a way to do this. Below is the javascript I am currently using to render the map: var myOptions = { zoom: 10, mapTypeId: google.maps.MapTypeId.ROADMAP, center: new google.maps.LatLng( 40.4230,-98.7372) } map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); // Weather weatherLayer = new google.maps.weather.WeatherLayer({ temperatureUnits: google.maps.weather.TemperatureUnit.FAHRENHEIT }); weatherLayer.setMap(map); //Hobby Stores var storeLayer = new google.maps.FusionTablesLayer({ query: { select: "col2", from: "3991553" }, map: map, supressInfoWindows: true }); //Club Sites var siteLayer = new google.maps.FusionTablesLayer({ query: { select: "col13", from: "3855088" }, styles: [{ markerOptions: { iconName: "airports" }}], map: map, supressInfoWindows: true }); I'd like to be able to pass some type of parameter in the call to google.maps.FusionTableLayer that passes a value to be include in the info window, but can't find a way to do this. To view the actual page, visit www.dualrates.com. Enter your zipcode and select one of the airport markers to see the info window. You may have to zoom the map out to see an airfield.

  • creating new instance fails PHP

    - by as3isolib
    I am relatively new to PHP and having some decent success however I am running into this issue: If I try to create a new instance of the class GenericEntryVO, I get a 500 error with little to no helpful error information. However, if I use a generic object as the result, I get no errors. I'd like to be able to cast this object as a GenericEntryVO as I am using AMFPHP to communicate serialize data with a Flex client. I've read a few different ways to create constructors in PHP but the typical 'public function Foo()' for a class Foo was recommended for PHP 5.4.4 //in my EntryService.php class public function getEntryByID($id) { $link = mysqli_connect("localhost", "root", "root", "BabyTrackingAppDB"); if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT * FROM Entries WHERE id = '$id' LIMIT 1"; if ($result = mysqli_query($link, $query)) { // $entry = new GenericEntryVO(); this is where the problem lies! while ($row = mysqli_fetch_row($result)) { $entry->id = $row[0]; $entry->entryType = $row[1]; $entry->title = $row[2]; $entry->description = $row[3]; $entry->value = $row[4]; $entry->created = $row[5]; $entry->updated = $row[6]; } } mysqli_free_result($result); mysqli_close($link); return $entry; } //my GenericEntryVO.php class <?php class GenericEntryVO { public function __construct() { } public $id; public $title; public $entryType; public $description; public $value; public $created; public $updated; // public $properties; } ?>

  • How to backup Servers to an SSH-Host with low traffic and access to versions and encryption?

    - by leto
    Hello, I've not run backups for the past dont't remember anymore years for my personal stuff until waking up lately and realising contrary to my prior belief: Actually. I care! :) Now I have a central data server at home where I want to attach an external media to, to which I want to save backups of my most important stuff, like years of self-written scripts, database dumps, you name it. I've tinkered with rsync+ssh over the last two years, also tried tar over ssh, but don't know the simplest and most easy to maintain way to do it yet. Heres my workload: A typical LAMP-Server (<5GB Data) which I'd like to backup fully so lots of small files connected via 10Mbit My personal stuff (<750GB Data) from a Mac connected via GE My passwords in an encrypted container (100Mb) from OpenBSD connected via serial-PPP My E-Mail from the last ten years (<25GB) as Maildir which I need to keep in readable format Some archives (tar.*) which I need to backup only once and keep in readable format (Deleted my ideas, as I'm here for suggestions) What I need: 1. Use an ssh-tunnel for data transfer 2. Be quick with lots of small files 3. Keep revisions 4. Be sure the data I save is not corrupted 5. Intelligent resume functions and be able to deal with network congestion :) 6. Compressed and optionally encrypted storage 7. Be able to extract data from backup easily (filesystem like usage would be nice) How would and with what software would you backup this stuff? Hints to tools that can help solve only part of my problem (like encryption) also greatly appreciated. Greets

    Hi, I don't understand why I'm not getting the message as "username already exits" if type the username which is already in database. If the username in a server, then it is returning the value as "1" otherwise empty, and despite of successfully getting the value from the server based on username is present or not, and assigning the value to variable "x", I'm unable to get message when I pass already exist username. May I know? $(document).ready(pageInit); function pageInit() { $('#1').bind('blur',go); } function go() { var value = $('#1').val(); var x = 0; $.post('just.do',{username:value},function(data){ x = data; } ); if(x) { $('#para').show(); $('#para').html("Username already exits"); return false; } else { $('#para').hide(); return true; } }; EDIT: This is what I'm doing in post request in servlets: String user1 = request.getParameter("username"); if(user != null) { String query = "Select * from users where user_name="+"\""+user+"\""; b = db.doExecuteQuery(stmt,query); if(b) { out.write("1"); } }

  • How to fix a damaged/corrupted NTFS filesystem/partition without losing the data on it?

    - by Gareth
    I was going to install Fedora 15 along side my Windows 7 Starter on my Acer Apire One D255E and at some point during the resizing of the NTFS partition (the one with Windows on it) the setup failed. Now I cannot access this partition from any OS. When I tried to access it from a Fedora install running on a USB flashdrive I get this error: Error mounting: mount exited with exit code 12: Failed to read last sector (452534271): Invalid argument HINTS: Either the volume is a RAID/LDM but it wasn't setup yet, or it was not setup correctly (e.g. by not using mdadm --build ...), or a wrong device is tried to be mounted, or the partition table is corrupt (partition is smaller than NTFS), or the NTFS boot sector is corrupt (NTFS size is not valid). Failed to mount '/dev/sda5': Invalid argument The device '/dev/sda5' doesn't seem to have a valid NTFS. Maybe the wrong device is used? Or the whole disk instead of a partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around? It doesn't make a lot of sense to me but I was really hoping it would to someone and they can give me a way to restore the partition without losing everything on it (I have a lot of important notes from various classes on there)? Cheers.

Right now, after each submission it creates 3 records for album table and 3 records for images. I need it to be one record for album and 3 for images, plus to link images to the album. I hope it all makes sense... Here is my structure. TABLE `albums` ( `id` int(11) NOT NULL auto_increment, `title` varchar(50) NOT NULL, `fullname` varchar(40) NOT NULL, `email` varchar(100) NOT NULL, `created_at` datetime NOT NULL, `theme_id` int(11) NOT NULL, `description` int(11) NOT NULL, `vote_cache` int(11) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=20 ; TABLE `images` ( `id` int(11) NOT NULL auto_increment, `album_id` int(11) NOT NULL, `name` varchar(30) NOT NULL, and my code function create_album($params) { db_connect(); $query = sprintf("INSERT INTO albums set albums.title = '%s', albums.email = '%s', albums.discuss_url = '%s', albums.theme_id = '%s', albums.fullname = '%s', albums.description = '%s', created_at = NOW()", mysql_real_escape_string($params['title']), mysql_real_escape_string($params['email']), mysql_real_escape_string($params['theme_id']), mysql_real_escape_string($params['fullname']), mysql_real_escape_string($params['description']) ); $result = mysql_query($query); if(!$result) { return false; } $album_id = mysql_insert_id(); return $album_id; } if(!is_uploaded_file($_FILES['userfile']['tmp_name'][$i])) { $warning = 'No file uploaded'; } elseif is_valid_file_size($_FILES['userfile']['size'][$i])) { $_POST['album']['theme_id'] = $theme['id']; create_album($_POST['album']); mysql_query("INSERT INTO images(name) VALUES('$newName')"); copy($_FILES['userfile']['tmp_name'][$i], './photos/'.$original_dir.'/' .$newName.'.jpg');

  • Large Product catalog with statistics - alternatives to Sql Server?

    - by Eric P
    I am building UI for a large product catalog (millions of products). I am using Sql Server, FreeText search and ASP.NET MVC. Tables are normalized and indexed. Most queries take less then a second to return. The issue is this. Let's say user does the search by keyword. On search results page I need to display/query for: First 20 matching products (paged, sorted) Total count of matching products for paging List of stores only of matching products List of brands only of matching products List of colors only of matching products Each query takes about .5 to 1 seconds. Altogether it is like 5 seconds. I would like to get the whole page to load under 1 second. There are several approaches: Optimize queries even more. I already spent a lot of time on this one, so not sure it can be pushed further. Load products first, then load the rest of the information using AJAX. More like a workaround. Will need to revise UI. Re-organize data to be more Report friendly. Already aggregated a lot of fields. I checked out several similar sites. For ex. zappos.com. Not only they display the same information as I would like in under 1 second, but they also include statistics (number of results in each category). The following is the search for keyword "white" http://www.zappos.com/white How do sites like zappos, amazon make their results, filters and stats appear almost instantly?

  • How can I get a list of modified records from a SQL Server database?

    - by Pixelfish
    I am currently in the process of revamping my company's management system to run a little more lean in terms of network traffic. Right now I'm trying to figure out an effective way to query only the records that have been modified (by any user) since the last time I asked. When the application starts it loads the job information and caches it locally like the following: SELECT * FROM jobs. I am writing out the date/time a record was modified ala UPDATE jobs SET Widgets=@Widgets, LastModified=GetDate() WHERE JobID=@JobID. When any user requests the list of jobs I query all records that have been modified since the last time I requested the list like the following: SELECT * FROM jobs WHERE LastModified>=@LastRequested and store the date/time of the request to pass in as @LastRequest when the user asks again. In theory this will return only the records that have been modified since the last request. The issue I'm running into is when the user's date/time is not quite in sync with the server's date/time and also of server load when querying an un-indexed date/time column. Is there a more effective system then querying date/time information?

  • MySQL Datefields: duplicate or calculate?

    - by Konerak
    We are using a table with a structure imposed upon us more than 10 years ago. We are allowed to add columns, but urged not to change existing columns. Certain columns are meant to represent dates, but are put in different format. Amongst others: * CHAR(6): YYMMDD * CHAR(6): DDMMYY * CHAR(8): YYYYMMDD * CHAR(8): DDMMYYYY * DATE * DATETIME Since we now would like to do some more complex queries, using advanced date functions, my manager proposed to d*uplicate those problem columns* to a proper FORMATTED_OLDCOLUMNNAME column using a DATE or DATETIME format. Is this the way to go? Couldn't we just use the STR_TO_DATE function each time we accessed the columns? To avoid every query having to copy-paste the function, I could still work with a view or a stored procedure, but duplicating data to avoid recalculation sounds wrong. Solutions I see (I guess I prefer 2.2.1) 1. Physically duplicate columns 1.1 In the same table 1.1.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.1.2 Maintained by a trigger on each modification 1.2 In a separate table 1.2.1 Added by each script that does a modification (INSERT/UPDATE/REPLACE/...) 1.2.2 Maintained by a trigger on each modification 2. On-demand transformation 2.1 Each query has to perform the transformation 2.1.1 Using copy-paste in the source code 2.1.2 Using a library 2.1.3 Using a STORED PROCEDURE 2.2 A view performs the transformation 2.2.1 A separate table replacing the entire table 2.2.2 A separate table just adding the date-fields for the primary keys Am I right to say it's better to recalculate than to store? And would a view be a good solution?
