  • Variable in one query is getting into another query in view

    - by Jason Shultz
    I have two foreach statements. The variable from one one is somehow getting into another and i'm not sure how to fix it. Here's my controller: // Categories Page Code function categories($id) { $this->load->model('Business_model'); $data['businessList'] = $this->Business_model->categoryPageList($id); $data['catList'] = $this->Business_model->categoryList(); $data['featured'] = $this->Business_model->frontPageList(); $data['user_id'] = $this->tank_auth->get_user_id(); $data['username'] = $this->tank_auth->get_username(); $data['page_title'] = 'Welcome To Jerome - Largest Ghost Town in America'; $data['page'] = 'category_view'; // pass the actual view to use as a parameter $this->load->view('container',$data); } What happens is categories will only show the businesses in a certain category. The businesses are pulled from the database using the categoryPageList($id) function. Here is that function: function categoryPageList($id) { $this->db->select('b.id, b.busname, b.busowner, b.webaddress, p.thumb, v.title, c.catname, s.specname, p.thumb, c.id'); $this->db->from ('business AS b'); $this->db->where('b.category', $id); $this->db->join('photos AS p', 'p.busid = b.id', 'left'); $this->db->join('video AS v', 'v.busid = b.id', 'left'); $this->db->join('specials AS s', 's.busid = b.id', 'left'); $this->db->join('category As c', 'b.category = c.id', 'left'); $this->db->group_by("b.id"); return $this->db->get(); } And here is the view: <h2>Welcome to Jerome, Arizona</h2> <p>Choose the Category of Business you are interested in:<br/> <?php foreach ($catList->result() as $row): ?> <a href="/site/categories/<?=$row->id?>"><?=$row->catname?></a>, &nbsp; <?php endforeach; ?></p> <table id="businessTable" class="tablesorter"> <thead><tr><th>Business Name</th><th>Business Owner</th><th>Web</th><th>Photos</th><th>Videos</th><th>Specials</th></tr></thead> <?php if(count($businessList) > 0) : foreach ($businessList->result() as $crow): ?> <tr> <td><a href="/site/business/<?=$crow->id?>"><?=$crow->busname?></a></td> <td><?=$crow->busowner?></td> <td><a href="<?=$crow->webaddress?>">Visit Site</a></td> <td> <?php if(isset($crow->thumb)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->title)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->specname)):?> yes <?php else:?> no <?php endif?> </td> </tr> <?php endforeach; ?> <?php else : ?> <td colspan="4"><p>No Category Selected</p></td> <?php endif; ?> </table> The problem occurs here. <?=$crow->id?> should be showing the row id from the business table. Instead, it's showing the row ID of the category table. so, if i'm viewing /site/categories/6 <?=$crow->id?> will show 6 when it should be showing 10 (the row ID of the only business in that category at this time. How can I fix this?

  • OSX Lion - sh: mysql command not found

    - by mkk
    I have pretty simple issue I believe. I have successfully installed mysql etc. I do not have any problems with running "mysql" command from terminal [ bash ]. Suddenly, when my application tried to run mysql command I got error: sh: mysql: command not found.. In terminal, when I type sh and then mysql I can log in to mysql without any problems. I have added mysql to PATH in .bash_profile and I suspect this is why sh cannot see it. I have cp .bash_profile to .profile but it did not do the trick, any ideas how can I fix this issue?

  • How to create a UDF that takes a query string and returns the query's resultset

    - by Martin
    I want to create a stored procedure that takes a simple SELECT statement and return the resultset as a CSV string. So the basic idea is get the sql statement from user input, run it using EXEC(@stmt) and convert the resultset to text using cursors. However, as SQLServer doesn't allow: select * from storedprocedure(@sqlStmt) UDF with EXEC(@sqlStmt) so I tried Insert into #tempTable EXEC(@sqlStmt), but this doesn't work (error = "invalid object name #tempTable"). I'm stuck. Could you please shed some light on this matter? Many thanks EDIT: Actually the output (e.g CSV string) is not important. The problem is I don't know how to assign a cursor to the resultset returned by EXEC. SP and UDF do not work with Exec() while creating a temp table before inserting values is impossible without knowing the input statement. I thought of OPENQUERY but it does not accept variables as its parameters.

  • Fulltext search for django : Mysql not so bad ? (vs sphinx, xapian)

    - by Eric
    I am studying fulltext search engines for django. It must be simple to install, fast indexing, fast index update, not blocking while indexing, fast search. After reading many web pages, I put in short list : Mysql MYISAM fulltext, djapian/python-xapian, and django-sphinx I did not choose lucene because it seems complex, nor haystack as it has less features than djapian/django-sphinx (like fields weighting). Then I made some benchmarks, to do so, I collected many free books on the net to generate a database table with 1 485 000 records (id,title,body), each record is about 600 bytes long. From the database, I also generated a list of 100 000 existing words and shuffled them to create a search list. For the tests, I made 2 runs on my laptop (4Go RAM, Dual core 2.0Ghz): the first one, just after a server reboot to clear all caches, the second is done juste after in order to test how good are cached results. Here are the "home made" benchmark results : 1485000 records with Title (150 bytes) and body (450 bytes) Mysql 5.0.75/Ubuntu 9.04 Fulltext : ========================================================================== Full indexing : 7m14.146s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:11.553524 next run : 0:00:00.168508 Mysql 5.5.4 m3/Ubuntu 9.04 Fulltext : ========================================================================== Full indexing : 6m08.154s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:11.553524 next run : 0:00:00.168508 1 thread, 100000 searchs with single word randomly taken from database : First run : 9m09s next run : 5m38s 1 thread, 10000 random strings (random strings should not be found in database) : just after the 100000 search test : 0:00:15.007353 1 thread, boolean search : 1000 x (+word1 +word2) First run : 0:00:21.205404 next run : 0:00:00.145098 Djapian Fulltext : ========================================================================== Full indexing : 84m7.601s 1 thread, 1000 searchs with single word randomly taken from database with prefetch : First run : 0:02:28.085680 next run : 0:00:14.300236 python-xapian Fulltext : ========================================================================== 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:26.402084 next run : 0:00:00.695092 django-sphinx Fulltext : ========================================================================== Full indexing : 1m25.957s 1 thread, 1000 searchs with single word randomly taken from database : First run : 0:01:30.073001 next run : 0:00:05.203294 1 thread, 100000 searchs with single word randomly taken from database : First run : 12m48s next run : 9m45s 1 thread, 10000 random strings (random strings should not be found in database) : just after the 100000 search test : 0:00:23.535319 1 thread, boolean search : 1000 x (word1 word2) First run : 0:00:20.856486 next run : 0:00:03.005416 As you can see, Mysql is not so bad at all for fulltext search. In addition, its query cache is very efficient. Mysql seems to me a good choice as there is nothing to install (I need just to write a small script to synchronize an Innodb production table to a MyISAM search table) and as I do not really need advanced search feature like stemming etc... Here is the question : What do you think about Mysql fulltext search engine vs sphinx and xapian ?

  • Is there any er diagram tool in Windows that I can use to connect to a MySQL 4.1 database in Unix?

    - by melaos
    I have a few test databases in some Unix SUSE 8 servers and initially the plan was to find some tools which can directly create the ERD straight from the server until someone told me that I can find tools to connect from the Windows PC straight to the Unix MySQL database. So I saw MySQL query analyzer which can do this but unfortunately there are no options to create an ERD. So are there any tools, preferably open source or free which can do this? I've done some basic googling but didn't know what is the exact terms to use to search for this and have so far found nothing useful yet. Updates: I just found out that the latest version of workbench doesn't work MySQL 4.1 Enterprise Edition which is the version that I have! And I try to use fabFORCE DBDesigner but I can't even connect at all using that one :( What can work for this version of MySQL?

  • Using SVN with a MySQL database ran by xamp - yes or no? (and how?)

    - by Extrakun
    For my current PHP/MySQL project (over a group of 4 to 5 team members), we are using this setup: each developer codes and test on his localhost running xamp, and upload to a test server via SVN. One question that I have now is how to synchronize the MySQL database? I may have added a new table to project and the PHP code references to it, so my other team members would need to access that table for my code (once they got it through SVN) to work. We are not always working in the same office all the time, so having a LAN and a MySQL server in the office is not feasible. So I am toying with 2 solutions Setup a test DB online, and have all the coders will reference to that, even when coding from localhost. Downside: you can't test if you happen not have internet access. Somehow sync the localhost copy of MySQL DB. Is that kind of silly? And if I do consider this, how do I do it? (which folder do I add to SVN?) (I guess a related question is how to automatically update the live MySQL DB from the testing DB, regardless if it is on a remote server or hosted locally via xamp. Any advice regarding that would be welcomed!)

  • Pros/Cons of MySQL vs Postgresql for production Ruby on Rails environment?

    - by cakeforcerberus
    I will soon be switching from sqlite3 to either postgres or mysql. What should I consider when making this decision? Is mysql more suited for Rails than postgres in some areas and/or vice versa? Or, as I somewhat suspect, does it not really matter either way? Another factor that might play into my decision is the availability of tools to data pump my test data from the sqlite3 db to my new one. Is there anything that ActiveRecord provides natively to do this or any decent plugins/gems to help with this task? BONUS: How do I pronounce "Postgresql" and sound like I know what I'm talking about? :) Thanks Greg Smith for providing the following link that shows the most common pronunciations: http://www.postgresql.org/community/survey.33 UPDATE: Reference this question for more: http://stackoverflow.com/questions/110927/do-you-recommend-postgresql-over-mysql FYI: I ended up using MySQL. There is a neat plugin called yamldb that really saved me some time with the data transfer from my sqlite db to my new mysql one. Instructions on how to install and use it can be found here: http://accidentaltechnologist.com/ruby/change-databases-in-rails-with-yamldb/ Thanks Tom

  • Possible to recover mysql root pass with sudo server access?

    - by jonathonmorgan
    I've inherited development for a website on vps hosting, and have login info for a user with sudo privileges, but don't have the password for the mysql root user. After digging around a little, it looks like the only way to fix this is to stop mysql (something like this: http://waoewaoe.wordpress.com/2010/02/03/recover-reset-mysql-root-password/). But because the website it's serving is currently in production, I'm hoping you guys can enlighten me to any potential consequences (or let me know if there's typically a file where the password would be accessible). a) during the time mysql is stopped, information in the database won't be accessible, right -- even by other users? b) will resetting the root password have any impact on other users after mysql has restarted? Will their username/passwords still be valid? The current application is using an account with limited privileges to read/write to the database, and while 5min downtime in the middle of the night would probably go unnoticed, half a day while I tie up loose ends/figure out what I screwed up will land in me hot water. Thanks in advance for your help!

  • Getting content from PHP: Trouble with POST and query.

    - by vgm64
    Apologies for my longest question on SO ever. I'm trying to interface with a php frontend for a mysql database in ROOT (a CERN framework in C++ for high energy physics analysis). To start off with, I tried to get this php interface to play nice with wget and curl first because I'm more familiar with them. The following command works: wget --post-data "hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases;" http://some.host.edu/log/log_query_matlab.php The results are: database1 database2 That's good. If I leave out the --post-data then I get the result: Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 6 i'm dead! Access denied for user 'admin'@'localhost' (using password: NO) Warning: mysql_query() [function.mysql-query]: Access denied for user 'admin'@'localhost' (using password: NO) in /log/log_query_matlab.php on line 29 Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /log/log_query_matlab.php on line 29 I have access to the php script (read only), but the error itself isn't too important. What matters it that using ROOT, I use a function called as socket.SendRaw(message, message.Length()) (socket is a TSocket) and this gives me the same "error" as wget without the post data switch if my "message" is "POST http://some.host.edu/log/log_query_matlab.php?hostname=localhost:3306&un=joeuser&pw=psswd&myquery=show_spazio_databases" This may be in vain, but does someone knows a way I should format the "message" that includes something that is equivalent to the --post-data switch. Or, is there a standard way to format POST requests in a single line (I've seen multi-line stuff. Is that right?) Sorry I'm clueless! PS. The mysql query is show databases but the space has been replaced with _spazio_, Italian for space. The author of the db and php interface requires it (and various replacements for symbols), but has anyone seen this before? Trying to troubleshoot that was terrible!

  • Why is MySQL with InnoDB doing a table scan when key exists and choosing to examine 70 times more ro

    - by andysk
    Hello, I'm troubleshooting a query performance problem. Here's an expected query plan from explain: mysql> explain select * from table1 where tdcol between '2010-04-13:00:00' and '2010-04-14 03:16'; +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ | 1 | SIMPLE | table1 | range | tdcol | tdcol | 8 | NULL | 5437848 | Using where | +----+-------------+--------------------+-------+---------------+--------------+---------+------+---------+-------------+ 1 row in set (0.00 sec) That makes sense, since the index named tdcol (KEY tdcol (tdcol)) is used, and about 5M rows should be selected from this query. However, if I query for just one more minute of data, we get this query plan: mysql> explain select * from table1 where tdcol between '2010-04-13 00:00' and '2010-04-14 03:17'; +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ | 1 | SIMPLE | table1 | ALL | tdcol | NULL | NULL | NULL | 381601300 | Using where | +----+-------------+--------------------+------+---------------+------+---------+------+-----------+-------------+ 1 row in set (0.00 sec) The optimizer believes that the scan will be better, but it's over 70x more rows to examine, so I have a hard time believing that the table scan is better. Also, the 'USE KEY tdcol' syntax does not change the query plan. Thanks in advance for any help, and I'm more than happy to provide more info/answer questions.

    I manipulated some data from MySQL and the resulting dictionary "data" (print data) displays something like this : {'1': ['1', 'K', abc, 'xyz', None, None, datetime.date(2009, 6, 18)], '2': ['2', 'K', efg, 'xyz', None, None, None, None], '3': ['3', 'K', ijk, 'xyz', None, None, None, datetime.date(2010, 2, 5, 16, 31, 2)]} How do I create a table and insert these values in a MySQL table? In other words, how do I dump them to MySQL or CSV? Not sure how to deal with datetime.date and None values. Any help is appreciated.

  • LINQ Query using UDF that receives parameters from the query

    - by Ben Fidge
    I need help using a UDF in a LINQ which calculates a users position from a fixed point. int pointX = 567, int pointY = 534; // random points on a square grid var q = from n in _context.Users join m in _context.GetUserDistance(n.posY, n.posY, pointX, pointY, n.UserId) on n.UserId equals m.UserId select new User() { PosX = n.PosX, PosY = n.PosY, Distance = m.Distance, Name = n.Name, UserId = n.UserId }; The GetUserDistance is just a UDF that returns a single row in a TVP with that users distance from the points deisgnated in pointX and pointY variables, and the designer generates the following for it: [global::System.Data.Linq.Mapping.FunctionAttribute(Name="dbo.GetUserDistance", IsComposable=true)] public IQueryable<GetUserDistanceResult> GetUserDistance([global::System.Data.Linq.Mapping.ParameterAttribute(Name="X1", DbType="Int")] System.Nullable<int> x1, [global::System.Data.Linq.Mapping.ParameterAttribute(Name="X2", DbType="Int")] System.Nullable<int> x2, [global::System.Data.Linq.Mapping.ParameterAttribute(Name="Y1", DbType="Int")] System.Nullable<int> y1, [global::System.Data.Linq.Mapping.ParameterAttribute(Name="Y2", DbType="Int")] System.Nullable<int> y2, [global::System.Data.Linq.Mapping.ParameterAttribute(Name="UserId", DbType="Int")] System.Nullable<int> userId) { return this.CreateMethodCallQuery<GetUserDistanceResult>(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), x1, x2, y1, y2, userId); } when i try to compile i get The name 'n' does not exist in the current context

  • MySQL query very slow on Amazon RDS but really fast on my laptop?

    - by Luc
    I would love to know if anybody knows why this is happening. i've just migrated over to Amazon RDS for our website and our biggest query which takes .2 seconds to execute on my macbook takes 1.3 seconds to execute on the most expensive RDS instance. Obviously i've disabled query cache (and tested this) on my local computer and both databases are exactly the same. InnoDB, both have the same indexes etc. It's costing us a fortune ($2000 per month) for the fastest RDS instance and i'm losing faith quickly. any ideas?

  • mysql - how do I load data from a different configuration...

    - by Ronedog
    I'm not sure if this will make sense, but I'll give it a shot. My hard drive went down and I had to reinstall the os along with all my webserver configuration,etc. I kept a backup of the mysql database, but it doesn't contain all the tables...I added a couple tables after my last backup. I have access to the hard drive and the directory where the mysql data files are stored from the failed hard drive, but I don't know how to retrieve the data into my new mysql database. Is it even possible to get the raw data files from mysql and load them into a different instance? I'd even be happy if there was some way for phpmyadmin to show the data files, then I could dump out to a backup txt file, and reload them into my new configuration. Any help will be appreciated. thanks.

  • How can I have MySQL write outfiles as a different user?

    - by David Locke
    I'm working with a MySQL query that writes into an outfile. I run this query once every day or two and so I want to be able to remove the outfile without having to resort to su or sudo. The only way I can think of making that happen is to have the outfile written as owned by someone other than the mysql user. Is this possible? Edit: I am not redirecting output to a file, I am using the INTO OUTFILE part of a select query to output to a file. If it helps: mysql --version mysql Ver 14.12 Distrib 5.0.32, for pc-linux-gnu (x86_64) using readline 5.2

  • In MySQL how can I tell what character set a particular table is using?

    - by muudscope
    I have a large mysql table that I think might be using the wrong character set. If so I'll need to change it using ALTER TABLE mytable CONVERT TO CHARACTER SET utf8 But since this is a very large table, I'd rather not run this command unless I have to. So my question is, how can I ask mysql what the character set is on a particular table? I can call status in mysql to see the database's character set, but that doesn't necessarily mean all the tables have the same character set, right?

  • Recreation of DB using "mysql mydb < mydb.sql" is really slow when the table has tens of millions of

    - by Jian Lin
    It seems that a MySQL database that has a table with tens of millions of records will get a big INSERT INTO statement when the following mysqldump some_db > some_db.sql is done to back up the database. (is it 1 insert statement that handles all the records?) So when reconstructing the DB using mysql some_db < some_db.sql then the CPU is hardly busy (about 1.8% usage by the mysql process... I don't see a mysqld either?) and also the hard disk doesn't seem to be too busy... Last time, the whole restore process took 5 hours. Is there a way to make it faster? Such as, when doing mysqldump, can it break the INSERT statement into shorter ones, so that the mysql doesn't need to parse the line so hard when restoring the DB?

  • How can I check if a binary string is UTF-8 in mysql?

    - by Piotr Czapla
    I've found a Perl regexp that can check if a string is UTF-8 (the regexp is from w3c site). $field =~ m/\A( [\x09\x0A\x0D\x20-\x7E] # ASCII | [\xC2-\xDF][\x80-\xBF] # non-overlong 2-byte | \xE0[\xA0-\xBF][\x80-\xBF] # excluding overlongs | [\xE1-\xEC\xEE\xEF][\x80-\xBF]{2} # straight 3-byte | \xED[\x80-\x9F][\x80-\xBF] # excluding surrogates | \xF0[\x90-\xBF][\x80-\xBF]{2} # planes 1-3 | [\xF1-\xF3][\x80-\xBF]{3} # planes 4-15 | \xF4[\x80-\x8F][\x80-\xBF]{2} # plane 16 )*\z/x; But I'm not sure how to port it to MySQL as it seems that MySQL don't support hex representation of characters see this question. Any thoughts how to port the regexp to MySQL? Or maybe you know any other way to check if the string is valid UTF-8? UPDATE: I need this check working on the MySQL as I need to run it on the server to correct broken tables. I can't pass the data through a script as the database is around 1TB.
