  • Speed up csv export when using php from mysql database query

    - by John
    Ok, so i've got a web system (built on codeigniter & running on mysql) that allows people to query a database of postal address data by making selections in a series of forms until they arrive at the selection that want, pretty standard stuff. They can then buy that information and download it via that system. The queries run very fast, but when it comes to applying that query to the database,and exporting it to csv, once the datasets get to around the 30,000 record mark (each row has around 40 columns of which about 20 are all populated with on average 20 chars of data per cell) it can take 5 or so minutes to export to csv. So, my question is, what is the main cause for the slowness? Is it that the resultset of data from the query is so large, that it is running into memory issues? Therefore should i allow much more memory to the process? Or, is there a much more efficient way of exporting to csv from a mysql query that i'm not doing? Should i save the contents of the query to a temp table and simply export the temp table to csv? Or am i going about this all wrong? Also, is the fact that i'm using Codeigniters Active Record for this prohibitive due to the way that it stores the resultset? Any advice is welcome! Thank you for reading!

  • PHP Export Date range

    - by menormedia
    I have a working database export to xls but I need it to export a particular date range based on the 'closed' date. (See code below). For example, I'd like it to export all 'closed' dates for last month and/or this month (Range: Sept 1, 2012 to Sept 30, 2012 or Oct 1, 2012 to Oct 31, 2012) <?PHP //EDIT YOUR MySQL Connection Info: $DB_Server = "localhost"; //your MySQL Server $DB_Username = "root"; //your MySQL User Name $DB_Password = ""; //your MySQL Password $DB_DBName = "ost_helpdesk"; //your MySQL Database Name $DB_TBLName = "ost_ticket"; //your MySQL Table Name //$DB_TBLName, $DB_DBName, may also be commented out & passed to the browser //as parameters in a query string, so that this code may be easily reused for //any MySQL table or any MySQL database on your server //DEFINE SQL QUERY: //edit this to suit your needs $sql = "Select ticketID, name, company, subject, closed from $DB_TBLName ORDER BY closed DESC"; //Optional: print out title to top of Excel or Word file with Timestamp //for when file was generated: //set $Use_Titel = 1 to generate title, 0 not to use title $Use_Title = 1; //define date for title: EDIT this to create the time-format you need $now_date = DATE('m-d-Y'); //define title for .doc or .xls file: EDIT this if you want $title = "MDT Database Dump For Table $DB_TBLName from Database $DB_DBName on $now_date"; /* Leave the connection info below as it is: just edit the above.

  • How to automate wIntegrate import/export?

    - by Paul Ayling
    Our company uses pic database and wIntegrate 4.02 to interface with. How would I go about automating the .wis files for importing and exporting through wIntegrate? Is there some type of macro, software solution or built in routine I can use? At the moment I manually login to pic using wIntegrate and goto run - querybuilder and select the desired .wis script for importing and exporting data and select ok to run. This is not a solution, it needs to be automated. Anyone? Is there some type of point a click freeware recording software? I hate to do a hack job like that but I'm running out of ideas and no one seems to have worked with this software before...

  • SQL 2000 Backup/Export Process - Can't find SQL 2000 Enterprise Manager, Can't use Mgmt Studio Expre

    - by 1nsane
    I need to make a backup of a client's SQL 2000 database, however there are a few issues preventing me from doing so using the traditional methods. I've tried using SQL Management Studio Express, but the host doesn't give sufficient privileges to create a backup and I'm getting some strange error messages. I've also tried doing the "Generate Scripts" to recreate the schema, then using the DTS Wizard to migrate the data, but the IDs set up with the identity specification property are not consistent with the live database once copied over. This results in some foreign key breakage... If I remember correctly, I was able to use Microsoft SQL 2000 Enterprise Manager to perform the task before, but I can't find this anywhere... it seems Microsoft has pulled most SQL Server 2000 stuff from their site. Does anyone know where I can find a copy of Enterprise Manager (or a trial of SQL Server 2000, which I believe comes with the component)? Or conversely, does anyone know of any other tools (preferably non-commercial) that are capable of mirroring remote SQL Server 2000 DBs? Thanks!

  • pam_exec.so PAM module does not export variable PAM_USER as stated in the documentation

    - by davidparks21
    I'm trying to use the pam_exec.so PAM module to execute a script which needs to know the username/password coming from the application (OpenVPN in this case). I have a script that executes printenv >>afile, but I don't see all the environment variables that the man pages states that pam_exec.so exports (namely PAM_USER I think), I only see the following: PAM_SERVICE=openvpn PAM_TYPE=auth PWD=/usr/local/openvpn/bin SHLVL=1 A__z="*SHLVL I do successfully pick up the password off of STDIN and output it with this same script. But for the life of me I can't get the username. Any thoughts on what I should try next?

    I have a bunch of avi's I am converting to m4v, and I can do this in QuickTime by opening the video and then go 'Save As', select a folder, select the type (iPhone, Movie, etc), blah blah blah. But I have around 100 videos I want to do this with. Command line options? Or batch processing options in the GUI? Enlighten me, please. This is QuickTime X on Snow Leopard.

  • PhpMyAdmin import/export - strange character encoding issues.

    - by John Hunt
    Hello, I'm migrating a site to a new host, and there are a couple of databases on there. There's no SSH access so I'm stuck with phpmyadmin. The issue is that certain characters (namely just whitespace) seems to being corrupt on the new site (same html, and apache doesn't seem to be messing with any encodings - you can see the strange characters have changed when I use less on my linux machine after downloading a table dump from both servers.) The issue isn't as bad if I import into the new database as utf-8 - whitespace characters only have one funny A type symbol instead of two. I've been trying various combinations of character encoding etc to no avail. Exporting from: phpMyAdmin 2.6.2 MySQL 4.1.20 MySQL connection collation: utf8_general_ci MySQL charset: UTF-8 Unicode (utf8) Collation on tables and their fields is: latin1_swedish_ci Importing to: phpMyAdmin - 2.11.9.2 MySQL client version: 5.0.45 MySQL charset: UTF-8 Unicode (utf8) MySQL connection collation: utf8_general_ci The import sql has this kind of thing in it: ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=192 ; I get the impression this is actually a bug or something with mysqldump as nothing seems to work.. does anyone have any insight into this? Cheers, John.

    - by mxg
    Hi everyone! I tried to export an Excel file into PDF, but it looks horrible. I need at least that one row form Excel to be saved into a one row in PDF. I know that it is not so simple, because Excel does no have any page size. At least, they could make some estimations. Can anyone recommend me how to save in MS Office an excel file into PDF, to have a normal look? Thanks in Advance!

  • Printing the second page from a Calc sheet

    - by Luke
    I've created a simple invoice document in LibreOffice Calc and it consists of 2 pages. I have defined the print range for my document as: $A$1:$D$33,$D$34:$D$35 My first page holds the actual invoice information the second page is a single merged cell holding terms and conditions text (wrapped to the cell width). The second page is defined by a row break. When I export the sheet as a PDF the first page comes out great but the second page with the terms text is all wrong. On the left hand side I see a portion of text (looks like a single column) and when I select the text inside the PDF I can see it go of the page somewhere to the left. I get the same result in a print preview. I'm at a complete loss on how to approach this problem and any insight is much appreciated.

  • Best way to export an icon from photoshop?

    - by Mudtail
    Hi, I'm writing a program to notify me of new email. It's mostly complete, I'm just working on the notifyicon code now. It's supposed to display the usual application icon with a box containing the count of unread emails inside it. I created icons for this in photoshop, exported them as 16x16 transparent PNGs, then converted them into windows ico files using ConvertIcon.com. Given that the image was 16x16 and the WinXP system tray uses 16x16 icons, I would assume the images would work. HOWEVER, when I start the application and get an email, the icon's all blurry: http://cyndle.com/bPJ7

  • Take a psd and export all the layers into separate image files without using Photoshop

    - by Darren
    This is my first question here and I'm not sure if this is the appropriate site for my question, but here it goes. If this is not the correct site, please direct me to the correct one. I have a psd file. I simply want to extract the layers from it into separate image files. I do not have Photoshop and I've already used up the free Photoshop trial. I am running Mountain Lion on a MacBook Pro. I have installed Gimp, but I can't figure out how to do what I want. I have searched using Google, but have been completely unable to find a tutorial showing me how to do this. I would really appreciate instructions or a link to an appropriate tutorial. I have seen some answers here, but they simply say use Gimp, which doesn't help me.

  • Handout export to word from PowerPoint are too big :(

    - by nickjohn
    EDITED i am using power point lectures. i want to mail merge speaker data into the respective lecture. now thats not possible with ppt as far i know, so i have to convert these lectures to handout by using power point option "publishMS word handouts" and use word mail merger. this is good since it will keep the comments/notes added in slides in handouts aswell. but these exported handouts in word remain actual slides and retain link to original ppt rather than simply get exported as images. so the file size gets verrry big 10mb ppt = 212mb doc=88mb docx Is there any option to convert handouts exported from power point to word as images? i simply cant save them as pngs from powerpoint since that will not include the comments data. Thanks

  • Does exportfs disrupt users already utilizing those filesystems?

    - by CptSupermrkt
    I need to modify a servers /etc/exports file to export to an additional host. After modifying this file, for it to take effect (i.e. for the additional host to have access to the designated filesystem), I believe I have to run "exportfs" on the server exporting the filesystem. Does this disrupt users who are currently using filesystems that are exported from that serving host? I'm hoping to add this new host "silently", without disruption. Any additional advice related to this, common traps, things to be careful of, etc. would be appreciated if you have any. Edit: just in case...uname -a returns 2.6.32-358.18.1.el6.x86_64 #1 SMP Fri Aug 2 17:04:38 EDT 2013 x86_64 x86_64 x86_64 GNU/Linux

  • Photoshop How to save selection to PNG

    - by Aniti
    I have a largish PSD file with a couple of hundred layers, that I would like to extract selected areas from into PNG files. Areas can consist of a couple of layers. Being new to Photoshop, I have been using the following workaround. Duplicate needed layers into a new scratch PSD file of same size, TRIM to transparency, Save As PNG, undo TRIM, hide layers, rinse and repeat... I suppose I could do it without the scratch file and just crop selection, Save As PNG and undo, but there must be a nicer method. What other ways are there to accomplish this export of a selected area to PNG? EDIT: This is on Windows Xp running Photoshop CS3 Extended

  • SQL Server 2008 R2 Writing To Text File

  • Export 1 year of CVS to another repo?

    - by John Dibling
    We have a CVS repo with many years of history. It has become huge and unwieldly, so we would like to split this singe repo in to two repos: The main repo would have 1 year's worth of history, up to and including present day. This is where all dev work would take place. An archive repo would have the complete history, up to the point where the main repo would take over. This would be read-only, and only used to look at historical changes. Given that we are starting with one huge, monolithic CVS repo, is it possible to split it up in this way? How can this be accomplished?

  • Export files to remote server using TortoiseSVN

    - by Matt
    Hi, I'm using TortoiseSVN to keep revisions of my code. When I commit changes, I take note of what files have changed and upload them to my server using FTP. Here's my workflow: Edit files on local computer (eg. files in C:\Users\Me\web) Commit changes to local repository using rightclick- TortoiseSVN- SVN Commit. Take the files, open FileZilla (FTP client) and upload the files to a remote server. I was wondering if there was a way in which I could omit step 3 from my workflow. Basically I would like the changed files to be automatically uploaded to the remote server when I commit a version to the repository. Information about my computer environment: Windows 7 Ultimate x64 with TortoiseSVN x64 Notepad++ text editor Files edited are PHP, CSS, JS, HTML, etc. Server is running Linux with PHP 5.2 and MySQL. FileZilla is used to upload files. I can connect to the server via SSH if that is needed. Thank you in advance.

  • MySQL gzipped Export in PhpMyAdmin has wrong size in Mozilla

    - by Michal Gow
    That is really strange. I am using PhpMyAdmin 2.11.9.6 on Linux hosting. While I am Exporting databases using "gzipped" compression in Mozilla, I am getting files which have size of uncompressed database, but they seems to be downloading in incredible speed (10 times quicker than is possible using my ISP). So at the end: for database of 10M size I am getting 10M gzip downloaded in miniseconds it has indeed shown 10M size on drive it is corrupted Zip compression is working just fine (I am getting file with cca 1M size with fine content of compressed database) And the weirdest thing: that is happening for Mozilla Firefox (13.0.1) only, Internet Explorer 9 is downloading correct gzipped files... Any hint?

  • Where to export a truly global environment variable?

    - by Socio
    I want to set an environment variable that will be visible to all processes launched by Upstart. This is on a CentOS system, but I presume the same applies to Ubuntu given that they both use Upstart. Somewhere in /etc/init/ perhaps? Note that adding it in /etc/profile.d only applies to login shells. I want all processes (e.g cron, rc.local, etc) to see it. Obviously I'd prefer not to edit existing sys config files if it can be avoided.
