• Build a Sitemap but webpages don't use links

  - by THX1138.6

  Folks I am trying to build a sitemap (we need one badly) for a huge multi-page web app. Technically its not much more than a collection of php/MySQL web forms that use javascript instead of traditional linkage to access the many pages. >td width="100" align="center" ONMOUSEOVER="this.className='bgover'" ONMOUSEOUT="this.className='bgout'" onclick="location.href='../main.php'">Main Page</td> Above is code sample of how the links are currently managed. I know I can search through the various pages, nearly a 1000, and find these "location.href" variables and that will help me a sitemap for each section. But maybe there is an easier way? WE use Trac and SVN so perhaps I am going about this the wrong way? Any advice would be appreciated.

• Uploading a Website

  - by 01010011

  Hi, This is my first time building a website and using CodeIgniter for a school project. I was wondering whether you have any tips on uploading CI to a free web host , my database, free webhosting and basic security tips. Can I just upload the entire CI folder? Or do I have to upload individual files (God no!)? What are my options? What about my MySQL database - do I just upload my mysqldump to the webhost? Also, can you recommend a good free webhost. I was thinking about 000webhost. Any basic tips on security would also be appreciated (I've implemented many of the form_validation rules like xss_clean for starters) Any other suggestions will be more than welcome. Thanks!

• Are indexes good or bad for a large database?

  - by gmemon

  Hello All, I read on MySQL Performance Blog that when tables are large, it is better to scan full tables, instead of using indexes. I have a table with tens of millions of rows. When conducting queries, if I use no indexes, then queries are 24 times slower than with indexes. I know lot of things may cause this (e.g., are rows stored sequentially), but can you please give me some hints what might be happening? Or how I should start examining this issue? I want to understand when use of indexes is preferred and when it's not Thanks

• Is this SQL select code following good practice?

  - by acidzombie24

  I am using sqlite and will port to mysql (5) later. I wanted to know if I am doing something I shouldnt be doing. I tried purposely to design so I'll compare to 0 instead of 1 (I changed hasApproved to NotApproved to do this, not a big deal and I haven't written any code). I was told I never need to write a subquery but I do here. My Votes table is just id, ip, postid (I don't think I can write that subquery as a join instead?) and that's pretty much all that is on my mind. Naming conventions I don't really care about since the tables are created via reflection and is all over the place. select id, name, body, upvotes, downvotes, (select 1 from UpVotes where IPAddr=? AND post=Post.id) as myup, (select 1 from DownVotes where IPAddr=@0 AND post=Post.id) as mydown from Post where flag = '0' limit ?, ?"

• Scraping html WITHOUT uniquie identifiers using python

  - by Nicholas Law

  I would like to design an algorithm using python that scrapes thousands of pages like this one and this one, gathers all the data and inserts it into a MySQL database. The script will be run on a weekly or bi-weekly basis to update the database of any new information added to each individual page. Ideally I would like a scraper that is easy to work with for table structured data but also data that does not have unique identifiers (ie. id and classes attributes). Which scraper add-on should I use? BeautifulSoup, Scrapy or Mechanize? Are there any particular tutorials/books I should be looking at for this desired result? In the long-run I will be implementing a mobile app that works with all this data through querying the database.

• Hyperlinks within a table - '<a href="">'.$row['username'].'</a>'

  - by Taimur

  Hi, I have made a leaderboard table on my site, which returns the users in the MySQL database with the highest scores (score is a separate field). The fields in the leaderboard table are 'rank' 'username' and 'score'. I would like to link each username in the table to it's own profile page. The profile pages are in the format /profile.php?user=$username. How would I go about adding an <a href> within the table (which is echoed in php): echo '<tr><td>' .$a. '</td><td><a href="profile.php?user=' .$row['username']. '">' .$row['username']. '</a></td><td>'.$row['count'].'</td></tr>'; I've tried the above, but it doesn't seem to work. It shows the usernames, but they don't have any hyperlinks. Thanks

• Need Insight - What is the best practice for syncing up a production database that will be used on a

  - by james

  I have a site set up using CakePHP and MySQL and I want to work on a test database without disrupting my live site in case something goes wrong. I have another busy site, but my test site runs off the live database which can be occasionally nerve wracking. What do I do if I change a table name in the test db and I want it changed in the live database? Or if I remove a record from the test database. Is there a way to diff the changes? How do I even merge those changes? How does this interfere with live user edits and things of that nature? Hopefully some of you working devs can share some insight!

• Adding a child node to a JSON node dynamically

  - by Sai

  I have to create a nested multi level json depending on the resultset that I get from MYSQL. I created a json object initially. Now I want to add child nodes to the already child nodes in the object. d = collections.OrderedDict() jsonobj = {"test": dict(updated_at="today", ID="ID", ads=[])} for rows1 in rs: jsonobj['list']["ads"].append(dict(unit = "1", type ="ad_type", id ="123", updated_at="today", x_id="111", x_name="test")) cur.execute("SELECT * from f_test") rs1 = cur.fetchall() for rows2 in rs1: propertiesObj = [] d["name"]="propName" d["type"]="TypeName" d["value"]="Value1" propertiesObj.append(d) jsonobj['play_list']["ads"].append() Here in the above line I want to add another child node to [play_list].[ads] which is a array list again. the output should look like the following [list].[ads].[preferences].

• usage of intval & real_escape_string when sanitizing integers

  - by paulus

  dear All. I'm using integer PKs in some tables of mysql database. Before input from PHP script, I am doing some sanitizing, which includes intval($id) and $mysqli-real_escape_string(). The queries are quite simple insert into `tblproducts`(`supplier_id`,`description`) values('$supplier_id','$description') In this example, $description goes through real_escape_string(), while $supplier_id only being intval()'ed. I'm just curious, if there're any situations, when I need to apply both intval and real_escape_string to integer I'm inserting into DB? So basically do I really need to use? $supplier_id = intval($mysqli->real_escape_string($supplier_id)); Thank you.

• How to fetch a random record from SQLite database?

• How do I ensure data consistency in this concurrent situation?

  - by MalcomTucker

  The problem is this: I have multiple competing threads (100+) that need to access one database table Each thread will pass a String name - where that name exists in the table, the database should return the id for the row, where the name doesn't already exist, the name should be inserted and the id returned. There can only ever be one instance of name in the database - ie. name must be unique How do I ensure that thread one doesn't insert name1 at the same time as thread two also tries to insert name1? In other words, how do I guarantee the uniqueness of name in a concurrent environment? This also needs to be as efficient as possible - this has the potential to be a serious bottleneck. I am using MySQL and Java. Thanks

• How to update existing record if the one being saved has the same key?

  - by Pavel Shved

  MySQL has a very nice option for INSERT statement, which is particularly helpful for join tables without the id column. It inserts a record, but, instead of throwing an error if its key clashed with the existing one, that record is updated. Here's an example: INSERT INTO table (key1,key2,data) VALUES (1,2,3) ON DUPLICATE KEY UPDATE c=3; How to achieve the same with ActiveRecord? The code looks like this: class Model < ActiveRecord::Base belongs_to :key1 belongs_to :key2 end record = Model.new record.key1 = key1 record.key2 = key2 record.data = 'new data' record.WHAT? #Inserts or updates `data` for the existing record

• Resources for dashboard app backend design

  - by Nix

  I am looking for examples of code/data/infrastructure design for a dashboard-style webapp. I am designing an interface for staff and faculty at a university to access departmental resources and be alerted of cyclical processes, events, deadlines, etc. Technologies I am working with: apache tomcat 6 and a mySQL database, JSP (including JSTL), bootstrap 3, and javascript/jquery. I have basic experience most of these technologies building smaller web apps but was hoping someone could direct me towards a book or other resource that discusses how to design the db architecture (and maybe how to template) for a dashboard, esp. for something like a notification systems. Any suggestions?

• Sum up values in SQL once all values are available

  - by James Brown

  I have events flowing into a MySQL database and I need to group and sum the events to transactions and store away into another table. The data looks like: +----+---------+------+-------+ | id | transid | code | value | +----+---------+------+-------+ | 1 | 1 | b | 12 | | 2 | 1 | i | 23 | | 3 | 2 | b | 34 | | 4 | 1 | e | 45 | | 5 | 3 | b | 56 | | 6 | 2 | i | 67 | | 7 | 2 | e | 78 | | 8 | 3 | i | 89 | | 9 | 3 | i | 90 | +----+---------+------+-------+ The events arrive in batches and I would like to create the transaction by summing up the values for each transid, like: select transid, sum(value) from eventtable group by transid; but only after all the events for that transid have arrived. That is determined by the event with the code e (b for the beginning, e for the end and i for varying amount of intermediates). Being a novice in SQL, how could I implement the requirement for the existance of the end code before the summing?

• How is this website fixing the encoding ??

  - by Tal Galili

  Hi all, I am trying to turn this text: ×וויר. העתיד של רשתות חברתיות והתקשורת ×©×œ× ×• Into this text: ?????. ????? ?? ????? ??????? ???????? ???? Somehow, this website: http://www.pixiesoft.com/flip/ Can do it, and I would like to know how I might be able to do it myself (with whatever programming language or software) Just saving the file as UTF8 won't do it. My motivation for this question is that I have a friend's exported XML file with the garbled text which I want to turn into corrected Hebrew text file. The XML export was originally garbled by MySQL import and exports, but I don't have the information needed to fix it or traceback the problem. Thanks.

• Attention all SQL gods! Query help needed.

  - by gurun8

  I need a little help putting together a SQL query that will give me the following resultsets: and The data model looks like this: The tricky part for me is that the columns to the right of the "Product" in the resultset are really columns in the database but rather key/value pairs spanned across the data model. Table data is as follows: My apologies in advance for the image heavy question and the image quality. This just seemed like the easiest way to convey the information. It'll probably take someone less time to write the query statement to achieve the results. By the way, the "product_option" table image is truncated but it illustrated the general idea of the data structure. The MySQL server version is 5.1.45.

• Getting Popular Topics on a Custom Made Forum

  - by Navarr

  For this website we're working on, we're trying to get the most popular topics (based on how many posts have been made in them within the last 24 hours). We have a medium to large based forum, and the current MySQL query looks like this: SELECT `forums_topics`.*, ( SELECT COUNT(`id`) FROM `forums_posts` WHERE `postdate` > (UNIX_TIMESTAMP()-60*60*24) AND `topicid`=`forums_topics`.`id` ) AS `trendy_threads` FROM `forums_topics` WHERE `deleted`=0 ORDER BY `trendy_threads` DESC,`postdate` DESC LIMIT 3 This unfortunately causes an SQL timeout with just one query and Error 500's. How can we get this information as quickly and as efficiently as possible?

• Resizing iframe height using javascript issue

  - by Camran

  I have an iframe which content is a php-file, and that php-file displays some mysql records. The more records, the larger the iframe height should get, otherwise it wont show all of the information in the iframe. Here is a code I have for dynamically setting the iframe height, from the iframes content (the php file): var x = document.body.scrollHeight; x = x + 20 + 'px'; window.parent.document.getElementById("iframe001").style.height=x; iframe001 is the iframe I am referring to above. I am adding 20px of height extra because of borders etc... Now, sometimes this resizing works, sometimes it doesn't. Does anybody know why it works sometimes. If I alert the 'x' variable, it shows different values sometimes, but most times it works. Any other ways you know of setting the iframes height from the content of the iframe? Thanks

• Why in the hell is this happening?

  - by user202411

  I just can't understand why is my database (mysql) behaving like this! My console shows that the record is created properly (please, notice the "remote_id" value): Tweet Create (0.3ms) INSERT INTO `tweets` (`remote_id`, `text`, `user_id`, `twitter_account_id`) VALUES (12325438258, 'jamaica', 1, 1) But when I check the record, it shows that the remote_id is 2147483647 intead of the provided value (12325438258 in the example above)... This table has many entries, but this field is always written with 2147483647... It was supposed to fill this space with an unique id (which I guarantee you is being generated properly).

• SQL Query taking too long

  - by user345426

  I am trying to optimize the SQL query listed below. It is basically a search engine code that retrieves products based on the products name. It also checks products model number and whether or not it is enabled. This executes in about 1.6 seconds when I run it directly through the phpMyAdmin tool but takes about 3 seconds in total to load in conjunction with the PHP file it is placed in. I need to add a category search functionality and now that is crashing the MySQL server, HELP!

• Any dynamic database frontend tool from which you can update directly?

  - by Enjoy coding

  Hi Gurus, This is with reference to this question where I got one tabular report format. I need to update the user entered values correctly back to the same table rows. I am in the process of doing this by using general form post data methods by using some logics which I think will not be easy to maintain. So, just out of curiosity, Is there a front end creator javascript libraries or frameworks which can create the front end for any query's resultset and updates the corresponding rows when the user updates them from front end. This need not have all the full functionality, any one usable, customizable thing will reduce the code maintenance problems. I have googled for some javascript libraris for this but not able to get which will be suitable. Please suggest any useful tools. My environment is Mysql, PHP, JQuery, XAMPP server on Windows. Is JQuery provides one. Thanks in advance.

• Some help needed with a SQL query

  - by Psyche

  Hello, I need some help with a MySQL query. I have two tables, one with offers and one with statuses. An offer can has one or more statuses. What I would like to do is get all the offers and their latest status. For each status there's a table field named 'added' which can be used for sorting. I know this can be easily done with two queries, but I need to make it with only one because I also have to apply some filters later in the project. Here's my setup: CREATE TABLE `test`.`offers` ( `id` INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY , `client` TEXT NOT NULL , `products` TEXT NOT NULL , `contact` TEXT NOT NULL ) ENGINE = MYISAM ; CREATE TABLE `statuses` ( `id` int(10) unsigned NOT NULL AUTO_INCREMENT, `offer_id` int(11) NOT NULL, `options` text NOT NULL, `deadline` date NOT NULL, `added` datetime NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1
