  • [php,mysql] insert only adds upto 1000 records and ignoresall records after that.

    - by user560559
    Hello i have a large database where the client stores personal messages and fire email notifications [if allowed by the users]. certain users have the option of sending messages to their entire network of friends. some users have over 5000 friends in their network so if they select the whole network they'll be sending messages to over 5000 friends and system will store all the messages into a table. the problem is this that it does not insert more than 1000 records and ignores all inserts after the first 1000. i have increased the packet size, bulk_insert_buffer_size but still no luck. since the system stores some of the info in another table for reports, every insert returns its new message id. due to this i can not use the "insert into table (column1,column2) values (value1,value2) , (value1,value2)....etc." table engine is innodb, mysql version is 5.1.3 and is hosted on amazon web services. all i want is to fix this issue of inserting more than 1000 records at a time. as mentioned earlier, it works fine but only up to 1000 records and simply ignores all the records after that. i'm using php foreach(){} to insert message for each friend and if email is available, send notification to the user. this foreach(){} also inserts the same record in another table [with only 3 columns] for generating reports. thank you in advance for all the help and support. WMA.

  • Implementing Tagging System with PHP and mySQL. Caching help!!!

    - by Hamid Sarfraz
    With reference to this post: http://stackoverflow.com/questions/2122546/how-to-implement-tag-counting I have implemented the suggested 3 table tagging system completely. To count the number of Articles per tag, i am using another column named tagArticleCount in the tag definition table. (other columns are tagId, tagText, tagUrl, tagArticleCount). If i implement realtime editing of this table, so that whenever user adds another tag to article or deletes an existing tag, the tag_definition_table is updated to update the counter of the added/removed tag. This will cost an extra query each time any modification is made. (at the same time, related link entry for tag and article is deleted from tagLinkTable). An alternative to this is not allowing any real time editing to the counter, instead use CRONs to update counter of each tag after a specified time period. Here comes the problem that i want to discuss. This can be seen as caching the article count in database. Can you please help me find a way to present the articles in a list when a tag is explored and when the article counter for that tag is not up to date. For example: 1. Counter shows 50 articles, but there are infact 55 entries in the tag link table (that links tags and articles). 2. Counter shows 50 articles, but there are infact 45 extries in the tag link table. How to handle these 2 scenerios given in example. I am going to use APC to keep cache of these counters. Consider it too in your solution. Also discuss performance in the realtime / CRONNED counter updates.

  • INSERT..ON DUPLICATE KEY UPDATE - but NOT using the duplicate key to compare.

    - by calumbrodie
    I am trying to solve a problem I have inherited with poor treatment of different data sources. I have a user table that contains BOTH good and evil users. create table `users`( `user_id` int(13) NOT NULL AUTO_INCREMENT , `email` varchar(255) , `name` varchar(255) , PRIMARY KEY (`user_id`) ); In this table the primary key is currently set to be user_id. I have another table ('users_evil') which contains ONLY the evil users (all the users from this table are included in the first table) - the user_id's on this table do NOT correspond to those in the first table. I want to have all my users in one table, and simply flag which are good and which are evil. What I want to do is alter the user table and add a column ('evil') which defaults to 0. I then want to dump the data from my 'users_evil') table and then run an INSERT..ON DUPLICATE KEY UPDATE with this data into the first table (setting 'evil'=1 where the emails match) The problem is that the 'PK' is set to the user_id and not the 'email'. Any suggestions, or even another strategy to successfully achive this. Can I run this statement but treat another column as PK only for the duration of the statement.

  • MySQL ORDER BY returns things in (apparently) random order !?

    - by Luke H
    The following query: SELECT DISTINCT ClassName FROM SiteTree ORDER BY ClassName is returning things in no apparent order! I get the same result whether I quote column/table names, or use DISTINCT or not, or add ASC or DESC. I assumed the indexes might be broken, or something like this, so tried dropping and recreating. Also tried REPAIR TABLE and CHECK TABLE. The table collation is set to latin1_swedish_ci. All the textual columns are set to use UTF-8 and collation is set to utf8_general_ci What could be causing this?

  • Shrink a cell (in an absolutely-positioned ASP.NET table) to fit its contents?

    - by Giffyguy
    My webpage currently looks like this: <asp:Table runat="server" style="position: absolute; left: 0%; top: 82%; right: 0%; bottom: 0%; width: 100%; height: 18%" CellPadding="0" CellSpacing="0" GridLines="Both"> <asp:TableRow> <asp:TableCell> Content1 </asp:TableCell> <asp:TableCell Width="2.5%"> </asp:TableCell> <asp:TableCell > Content2 </asp:TableCell> </asp:TableRow> </asp:Table> But I need it to look like this: "Content1" is of unknown size, and the table will have to adjust to fit it in, but without taking any unnecessary space away from "Content2." I can't use "display: table" because it isn't supported in IE7 and such, so I'm pretty much stuck using a regular table element unless there is something better out there that is supported in older browsers. Does anyone know how this can be accomplished?

    - by understack
    I've this sample table and I want to make header row of table visible all the time. Header row should scroll with horizontal scrollbar and shouldn't scroll with vertical scrollbar. table: <div style="width:800px; height:150px;overflow:scroll;margin:50px auto;"> <table style="width:1600px" border="1"> <thead style=""> <tr> <th style="width:800px">id_1</th> <th style="width:800px">id_2</th> </tr> </thead> <tbody style=""> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> <tr><td>1200</td><td>1200</td></tr> </tbody> </table> </div> How can I do this with css only? Suggestions in this and this thread didn't seem to work, possibly due to presence of scrollbars.

  • Is it possible to inspect the contents of a Table Value Parameter via the debugger?

    - by Stephen Edmonds
    Does anyone know if it is possible to use the Visual Studio / SQL Server Management Studio debugger to inspect the contents of a Table Value Parameter passed to a stored procedure? To give a trivial example: CREATE TYPE [dbo].[ControllerId] AS TABLE( [id] [nvarchar](max) NOT NULL ) GO CREATE PROCEDURE [dbo].[test] @controllerData [dbo].[ControllerId] READONLY AS BEGIN SELECT COUNT(*) FROM @controllerData; END DECLARE @SampleData as [dbo].[ControllerId]; INSERT INTO @SampleData ([id]) VALUES ('test'), ('test2'); exec [dbo].[test] @SampleData; Using the above with a break point on the exec statement, I am able to step into the stored procedure without any trouble. The debugger shows that the @controllerData local has a value of '(table)' but I have not found any tool that would allow me to actual view the rows that make up that table.

  • How should I solve this MySql problem (PHP) ? (Beginner)

    - by Camran
    I have several tables in a MySql database. I have a classifieds website, and at the bottom I display the users last visited classifieds. I do this by storing the ID:s of the ads to an array in the cookie. Now, my db is made up like this kindof: Main Table: // Stores global information, ie these fields have to be filled out in every record, never be blank ID Price category Seller Item Table: // Stores descriptive info about whats for sale ID AD_ID (FK) //This is the same as ID in the MAIN TABLE Color Size Mileage etc My problem is that I need to know what category the ad is in, in order to query mysql for the right information I think. So I need two variables, but the cookie only has one (ID) stored. Offcourse I could make two queries, first one just matching the ID to the main_table and fetch the category from the Main_table. Then make the second query and fetch all other info from the right table. Here is an example if the category was Vehicles: SELECT * FROM main_table, vehicles_table, WHERE main_table.id=$id_from_cookie AND main_table.ad_id=vehicles_table.ad_id As you can see above, I need the category to write in what table to check, right? But I think there must be a smarter way, like fetching them in one single query using only one variable (id from cookie)? How should I do this? Understand? Let me know if you need more input... Thanks

  • What is the best practise for relational database tables in mysql?

    - by George
    Hi, I know, there is a lot of info on mysql out there. But I was not really able to find an answer to this specific and actually simple question: Let's say I have two tables: USERS (with many fields, e.g. name, street, email, etc.) and GROUPS (also with many fields) The relation is (I guess?) 1:n, that is ONE user can be a member of MANY groups. What I dis, is create another table, named USERS_GROUPS_REL. This table has only two fields: us_id (unique key of table USERS) and gr_id (unique key of table GROUPS) In PHP I do a query with join. Is this "best practice" or is there a better way? Thankful for any hint!

  • MySQL, replacing &nbsp; with... nothing (delete those, please!)

    - by javipas
    I'm trying to purge my WordPress content from "false" carriage return (CR). These are caused after a migration of my content, that now presents from time to time a &nbsp; code that makes the web rendering engine to "paint" a CR where I would like to be nothing. The paragraphs seem to have a double CR because of this, and look too far apart. I'd like to be able to make a MySQL query in order to get rid of that strings, but at the moment I haven't found the key. What I've tried is UPDATE wp_posts set post_content = replace (post_content,'&nbsp;',' '); But i get <p> </p> where before were the &nbsp; strings. This seems not the answer at all. Could it have to be with the ampersand, and in that case, should I use something like &amp;nbsp; or something similar?

  • Do I need to buy Mysql cluster enterprise edition?

    - by Arman
    Hello, we have a ms-sql 2008 standard edition. The db became too huge, about 8 10^9 records.the db files are about 4.5tb each. We cannot effort us to get enterprise edition to slice the database. We need partitioning. So the idea is to use Mysql cluster with many datanodes. We already started to move data. I wondered do we need to buy a licens for mysqlcluster?are there performance difference between community edition and commercial one? Thanks Arman.

  • When to increase AWS RDS MySQL Server instance to larger CPU/RAM?

    - by rksprst
    I'm wondering at what stage do I need to increase the image for the RDS MySQL server to a larger CPU/RAM instance. The CPU utilization graph is near 0. The Avg Free Memory is around 150MB. The Avg Swap Usage is 420MB. Read Latency is 0-20ms/op it spikes up randomly. Avg write latency is on average 5ms/op but spikes up to 10-20ms/op. Are there some common rules here that I should follow? Thanks!

  • EBS+RAID10+XFS slower than EBS+RAID10+EXT3 using MySQL?

    - by Johann Tagle
    We're currently using EC2 with 16 EBS volumes in RAID10 configuration for our MySQL data. I know some people don't recommend to put EBS volumes to RAID but that's not what I'm concerned about at the moment. Current format is ext3, but we're experimenting with moving to xfs, given many reports that it is faster. However, we're actually experiencing a performance degradation when the partition was converted to xfs - a benchmark run with inserts, updates, selects and deletes was more than 10 seconds slower using xfs. Any idea what could be the problem? Below is the fstab entry (really only changed ext3 to xfs). Database tables are innodb and we are using innodb_file_per_table. /dev/mapper/vg_data-lv_data /data xfs noatime 0 0 Thanks.

  • MySQL Windows vs. Linux: performance, caveats, pros and cons?

    - by gravyface
    Looking for (preferrably) some hard data or at least some experienced anecdotal responses with regards to hosting a MySQL database (roughly 5k transactions a day, 60-70% more reads than writes, < 100k of data per transaction i.e. no large binary objects like images, etc.) on Windows 2003/2008 vs. a Debian-based derivative (Ubuntu/Debian, etc.). This server will function only as a database server with a separate Web server on another physical box; this server will require remote access for management (SSH for Linux, RDP for Windows). I suspect that the Linux kernel/OS will compete less than the Windows Server for resources, but for this I can't be certain. There's also security footprint: even with Windows 2008, I'm thinking that the Linux box can be locked down more easily than the Windows Server. Anyone have any experience with both configurations?

  • Is it faster to create indexes before or after data loading in MySQL?

    - by Josh Glover
    I have a data replication process that drops and recreates a few tables in a target database, then loads them up with data from a source database (running on another host, but that is immaterial to the question at hand). The target database does need primary keys and a few other indexes on its tables, but not during the data loading. I'm currently loading all of the data, then creating the indexes. However, index creation takes a pretty long time--30 minutes of my data loader's 5 and a half hour running time. My intuition tells me that creating the indexes at the end should be faster than creating them first, since the index would need to be rewritten with each insert. Can anyone tell me for sure which way is faster? FWIW, I'm running MySQL 5.1 with InnoDB tables.

  • How to efficiently dump a huge MySQL innodb database?

    - by Jagbir
    I got an Ubuntu 10.04 production MySQL database server where total size of database is 260 GB while size of root partition is itself 300 GB where DB is stored, essentially means around 96% of / is full and there's no space left for storing dump/backup etc. No other disk is attached to server as of now. My task is to migrate this database to other server sitting in different datacenter. Question is how to do that efficiently with minimum downtime? I'm thinking in line of: Request to attach an extra drive to server and take a dump in that drive. Transfer dump to new server, restore it and make new server slave of existing one to keep data in sync When migration is needed, break replication, update slave config to accept read/write requests and make old server read-only so it won't entertain any write requests and tell app developers to update there config with new IP address for db. What's your suggestions to improve this or any alternate better approach for this task?

  • windows VPS running apache and mysql, php scripts running slow.. but cpu usage is 1-3%..

    - by Roeland
    So every night I run some cron jobs. It requires probably about 20 min to process all the records. I gather the script does something like 10,000 sql queries. I figure this task was just that intense and needs time to complete, but I looked at CPU and memory usage, and it is super low. Cpu usage is between 1-3% and once in a while will bounce to 50ish for 2-3 seconds. This VPS is running windows 2003 server with Apache and MySQL. Does this sound right?

  • Why is this MySQL FULLTEXT query returning 0 rows when matching rows are present?

    - by Don MacAskill
    I have a MySQL table with 200M rows which has a FULLTEXT index on two columns (Title,Body). When I do a simple FULLTEXT query in the default NATURAL LANGUAGE mode for some popular results (they'd return 2M+ rows), I'm getting zero rows back: SELECT COUNT(*) FROM itemsearch WHERE MATCH (Title, Body) AGAINST ('fubar'); But when I do a FULLTEXT query in BOOLEAN mode, I can see the rows in question do exist (I get 2M+ back, depending): SELECT COUNT(*) FROM itemsearch WHERE MATCH (Title, Body) AGAINST ('+fubar' IN BOOLEAN MODE); I have some queries which return ~500K rows which are working fine in either mode, so if it's result size related, it seems to crop up somewhere between 500K and a little north of 2M. I've tried playing with the various buffer size variables, to no avail. It's clearly not the 50% threshold, since we're not getting 100M rows back for any result. Any ideas?

  • MySQL: how to convert many MyISAM tables to InnoDB in a production database?

    - by Continuation
    We have a production database that is made up entirely of MyISAM tables. We are considering converting them to InnoDB to gain better concurrency & reliability. Can I just alter the myISAM tables to InnoDB without shutting down MySQL? What are the recommend procedures here? How long will such a conversion take? All the tables have a total size of about 700MB There are quite a large number of tables. Is there any way to apply ALTER TABLE to all the MyISAM tables at once instead of doing it one by one? Any pitfalls I need to be aware of? Thank you

  • After creating a mysql user with all privileges, the user cannot create databases in phpMyAdmin and only sees information_schema table

    This is a recurring problem for some reason... Using mysql 5.5, I am simply trying to create a user that can connect to the database remotely, have access to all databases, and create databases. I have created a user using: create user 'dev'@'%' identified by 'abcdefg'; then granted all permissions using: GRANT ALL ON *.* to 'dev'@'192.168.%' IDENTIFIED BY 'abcdefg' WITH GRANT OPTION; and the result is that the user cannot create databases, and can only see information_schema database for some reason.

  • How can I speed up a MySQL retore from a dump file?

    - by Dave Forgac
    I am restoring a 30GB database from a mysqldump file to an empty database on a new server. When running the SQL from the dump file, the restore starts very quickly and then starts to get slower and slower. Individual inserts are now taking 15+ seconds. The tables are MyISAM. The server has no other active connections. SHOW PROCESSLIST; only shows the insert from the restore (and the show processlist itself). Does anyone have any ideas what could be causing the dramatic slowdown? Are there any MySQL variables that I can change to speed the restore while it is progressing?
