• How do I create this array? (PHP)

  - by jpjp

  I am a little stuck on how to create this array. My data: category_id | category_name 1 bikes 2 cars 3 books 4 computers Array: $category=array(); $query = "SELECT * FROM categories ORDER BY name ASC"; $result = $db->query($query); $category=array('category_id'=>$category_id, 'category_name'=>$category_name); while ($row = $result->fetch_array()){ $category_id=$row['category_id']; $category_name=$row['name']; } I want to create an array so that I can echo the data in a radio list like... <input type='radio' value='<?PHP echo $category['category_id']; ?>' name='category[]'><?PHP echo $category['category_name']; ?> o bikes o cars o books o computers The problem is that the array only consists of one pair (1, bikes) and not all the data. How can I make an array with all the data? Thanks!

• Preventing SQL injecting in a database class

  - by Josh

  I'm building a database class and thought it'd be a good idea to incorporate some form of SQL injection prevention (duh!). Here's the method that runs a database query: class DB { var $db_host = 'localhost'; var $db_user = 'root'; var $db_passwd = ''; var $db_name = 'whatever'; function query($sql) { $this->result = mysql_query($sql, $this->link); if(!$this->result) { $this->error(mysql_error()); } else { return $this->result; } } } There's more in the class than that but I'm cutting it down just for this. The problem I'm facing is if I just use mysql_real_escape_string($sql, $this->link); then it escapes the entire query and leads to a SQL syntax error. How can I dynamically find the variables that need to be escaped? I want to avoid using mysql_real_escape_string() in my main code blocks, i'd rather have it in a function. Thanks.

• partial string matching - R

  - by DonDyck

  I need to write a query in R to match partial string in column names. I am looking for something similar to LIKE operator in SQL. For e.g, if I know beginning, middle or end part of the string I would write the query in format: LIKE 'beginning%middle%' in SQL and it would return matching strings. In pmatch or grep it seems I can only specify 'beginning' , 'end' and not the order. Is there any similar function in R that I am looking for? For example, say I am looking in the vector: y<- c("I am looking for a dog", "looking for a new dog", "a dog", "I am just looking") Lets say I want to write a query which picks "looking for a new dog" and I know start of the string is "looking" and end of string is "dog". If I do a grep("dog",y) it will return 1,2,3. Is there any way I can specify beginning and end in grep?

• Why delete and recreate a querydef object when you can just change the .SQL property?

  - by dblE

  Do you remember the venerable old Microsoft Query by Form (QBF) VBA example from back in the day link that recommended that you delete an existing query and then recreate it dynamically?: On Error Resume Next db.QueryDefs.Delete ("qryResults") On Error GoTo 0 Set qdf = db.CreateQueryDef("qryResults", "SELECT p.*... Why not just change the SQL property of the querydef object? qdf.SQL = "SELECT p.*... I am wondering if anyone knows why the MS engineers wrote an example that suggests that you delete and then recreate a query instead of simply changing the SQL property? I would guess that the act of deleting and recreating objects over time could contribute to corruption and bloating in your front end, not to mention changing the SQL property is so much simpler. Does anyone have more insight into this?

• How do I select the most recent entry in mysql?

  i want to select the most recent entry from a table and see if that entry is exactly the same as the one the user is trying to enter.

• How can I write my code to attempt a database action but continue executing code on failure?

  - by Chris

  Simple question I guess, I want to use PHP to write an update to an existing row in my database, if it doesn't happen I want to log the failure but continue executing the code. While it would be nice to have records of failures to track down issues, that the update failed isn't that important to my user, nor will it affect the running of any other code; the query is simply for a 'cosmetic' but entirely unnecessary piece of information. My database class's query function is set to die on failure, could I modify that or is there another way of doing it without altering my standard query code?

• Complex SQL queries (DELETE)?

  - by Joe

  Hello all, I'm working with three tables, and for simplicity's sake let's call them table A, B, and C. Both tables A and B have a column called id, as well as one other column, Aattribute and Battribute, respectively. Column c also has an id column, and two other columns which hold values for A.id and B.id. Now, in my code, I have easy access to values for both Aattribute and Battribute, and want to delete the row at C, so effectively I want to do something like this: DELETE FROM C WHERE aid=(SELECT id FROM A WHERE Aattribute='myvalue') AND bid=(SELECT id FROM B WHERE Battribute='myothervalue') But this obviously doesn't work. Is there any way to make a single complex query, or do I have to run three queries, where I first get the value of A.id using a SELECT with 'myvalue', then the same for B.id, then use those in the final query? [Edit: it's not letting me comment, so in response to the first comment on this: I tried the above query and it did not work, I figured it just wasn't syntactically correct. Using MS Access, for what it's worth. ]

  - by user3696018

  I have a database with details of daily sales. To query a database, I have a form in a view with parameters that will query as date of admission, client and others. The result is shown in another view with the daily details of income, and below is a summary of the article do all entered. The summary I wish to transfer to another view, try to view :: composer but only transfer the empty query (I saw it with debug bar). Just appeared an empty view. How I can transfer data from the database without the latter view is empty? The second html view is totaly diferent , only the data is the same.

• Why isn't INT more efficient than UNIQUEIDENTIFIER (according to the execution plan)?

  - by ck

  I have a parent table and child table where the columns that join them together are the UNIQUEIDENTIFIER type. The child table has a clustered index on the column that joins it to the parent table (its PK, which is also clustered). I have created a copy of both of these tables but changed the relationship columns to be INTs instead, have rebuilt the indexes so that they are essentially the same structure and can be queried in the same way. When I query for a known 20 records from the parent table, pulling in all the related records from the child tables, I get identical query costs across both, i.e. 50/50 cost for the batches. If this is true, then my giant project to change all of the tables like this appears to be pointless, other than speeding up inserts. Can anyone provide any light on the situation? EDIT: The question is not about which is more efficient, but why is the query execution plan showing both queries as having the same cost?

• insert into select from other table

  - by user3815079

  I need to add multiple records based on data from another table where the event is the same. I've found on this forum insert into table2(id,name) select "001",first_name from table1 where table1.id="001" as possible solution for my question. So I thought this should be the following syntax: insert into reservations(event,seat) select "99",id from seats where seats.id>0 to add all seats to event 99. However when I run this query mysql gives the message 'MySQL returned an empty resultset (0 rows). (query 0.0028 sec)' and no records were added. I translated the message so could be sligthly different. When I only use the "select "99",id from seats where seats.id0" query, it returns me 1080 rows.

• PHP - if == not working for 0 or ""

  - by user2933212

  I am checking the validation of the request with an if query, if ($request_userid == $userid) { ... } Thats working as expected. But further testing has shown, that if $request_userid or $userid is 0 or "", then the condition is true and the script runs the if query but it shouldn't. I am currently solving it with: if ($userid == "" ) { exit ("exit"); } But I don't think that this is the right way? Can you explain why it doesn’t work with the if query and what would be the correct way to check it?

• SQLite delete the last 25% of records in a database.

  - by Steven smethurst

  I am using a SQLite database to store values from a data logger. The data logger will eventually fills up all the available hard drive space on the computer. I'm looking for a way to remove the last 25% of the logs from the database once it reaches a certain limit. Using the following code: $ret = Query( 'SELECT id as last FROM data ORDER BY id desc LIMIT 1 ;' ); $last_id = $ret[0]['last'] ; $ret = Query( 'SELECT count( * ) as total FROM data' ); $start_id = $last_id - $ret[0]['total'] * 0.75 ; Query( 'DELETE FROM data WHERE id < '. round( $start_id, 0 ) ); A journal file gets created next to the database that fills up the remaining space on the drive until the script fails. How/Can I stop this journal file from being created? Anyway to combined all three SQL queries in to one statement?

• Installer not being updated ( probably because of Windows 7 file cache )

  - by Sithu Kyaw

  I'm creating an installer for my Visual FoxPro application using ISTool and Inno Setup. It is ok for me for the first time. But, I updated my code and re-built the EXE file. Then, compiled the installer again. I found that my update was not compiled into the installer and I did not see the update in my running application. I noticed that the EXE file, which was built by VFP, was updated properly. It seems the installation script did not output the updated file. But, when I changed folder names, it did work. I don't want to change folder names whenever I run that installation script. It is not a good idea actually. I think it is because of Windows 7 cache system. Mine is Windows 7 Home Premium Service Pack 1. For example, My previous output file is located at C:\path\to\myinstaller.exe When I compile the installation script, the output file there should be overwritten, but it was not as expected. Although I deleted the file, it did not work. When I changed to output file path as C:\newpath\to\myinstaller.exe, I got the fix, but it is not a solution what I'm looking for. Does anyone how to do that? [Edit] I found that the installed directory was not updated properly. For example, I installed the program to C:\Program files\MyInstalledApp When I run the installer again, that installation directory should be overwritten, but failed. Thus, I got to uninstall the app before I re-install it. Is there any fix for this?

• Openconnect for Cisco VPN doesn't recognize private key file - asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag

  - by Alexander Skwar

  I'm trying to use my Synology DS212 NAS box also act as VPN gateway to my companies VPN. Sadly, they only use Cisco ASA and to complicate stuff even further, we've got to use personal certificates (which is of course more secure, but more complicate to get going…). So I compiled OpenConnect v4.06 from http://www.infradead.org/openconnect/. As a very basic test, I tried to build a connection by manually invoking openconnect, passing along the key and cert files, like so: /lib/ld-linux.so.3 --library-path /opt/lib \ /opt/openconnect/sbin/openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 It fails :( Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Using client certificate '/[email protected]/OU=Company VPN' 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Loading private key failed (see above errors) Loading certificate failed. Aborting. Failed to open HTTPS connection to <ip> Failed to obtain WebVPN cookie When I run the same command with the same cert/key files on a Ubuntu 12.04 box, it works: openconnect \ --certificate=$VPN_CFG/alexander.crt \ --sslkey=$VPN_CFG/alexander.key \ --cafile=$VPN_CFG/Company_VPN_CA.crt \ --user=alexander --verbose <ip>:443 Attempting to connect to <ip>:443 Using certificate file $VPN_CFG/alexander.crt Extra cert from cafile: '/CN=Company AG VPN CA/O=Company AG/L=Zurich/ST=ZH/C=CH' SSL negotiation with <ip> Server certificate verify failed: self signed certificate Certificate from VPN server "<ip>" failed verification. Reason: self signed certificate Enter 'yes' to accept, 'no' to abort; anything else to view: yes Connected to HTTPS on <ip> GET https://<ip>/ […] Well… The error on the NAS is this: 5919:error:0D0680A8:asn1 encoding routines:ASN1_CHECK_TLEN:wrong tag:tasn_dec.c:1315: Any ideas, what's causing this? On Syno, I use OpenConnect 4.06. On Ubuntu, I just compiled and installed to a custom location OpenConnect 4.06 as well. Thanks, Alexander

• QT Creator 64-bit Snow Leopard

  - by quadelirus

  I have a bunch of libraries that I need to link against that I installed via macports. They are 64-bit libraries. I'm working on an application written with QT Creator and the .pro is set up. I downloaded the QT SDK for Mac OS X, but it is 32-bit and so the compiled code won't link against the 64-bit binaries that I got from macports. Ok. So I downloaded the QT SDK source and built from source using -arch x86_64. Now I have a 64-bit version of the SDK (I think) but it didn't build a QT Creator app. So. I need to know one of 4 things: Either, 1.) I'm guessing that a simple make command will convince the QT SDK to build the creator for me. If this is true, then what is the command (make creator?). barring that, I need to know 2.) The easiest way to get MacPorts to redownload the libraries that I installed with a 32-bit version (I keep seeing a "+universal" mentioned, but I haven't seen it on a line, and simply calling ports +universal install XYZ doesn't seem to work--perhaps I need to uninstall and reinstall the package?). Also, is this a stupid idea? or 3.) Someone who actually has a prebuilt 64-bit QT SDK installer so I don't have to mess with this. It is ridiculous that QT doesn't already have this available, in my opinion--SL has been out since, what, last August? 4--and this would take the cake.) I don't understand why I can't simply put a "compile-for-64-bit stupid" command directly into the QT pro file and have it build. There isn't really a reason why a compiler compiled in 32-bits couldn't compile to 64-bits is there? Thanks.

• Apache 2.2, worker mpm, mod_fcgid and PHP: Can't apply process slot

  - by mopoke

  We're having an issue on an apache server where every 15 to 20 minutes it stops serving PHP requests entirely. On occasions it will return a 503 error, other times it will recover enough to serve the page but only after a delay of a minute or more. Static content is still served during that time. In the log file, there's errors reported along the lines of: [Wed Sep 28 10:45:39 2011] [warn] mod_fcgid: can't apply process slot for /xxx/ajaxfolder/ajax_features.php [Wed Sep 28 10:45:41 2011] [warn] mod_fcgid: can't apply process slot for /xxx/statics/poll/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php There is RAM free and, indeed, it seems that more php processes get spawned. /server-status shows lots of threads in the "W" state as well as some FastCGI processes in "Exiting(communication error)" state.

• Follow cursor location from kile to evince.

  - by D Connors

  I know the title is probably not very clear, so I'll try to be as clear as possible here. I'm running xubuntu on my netbook, and I'm using kile for my latex editing. Since kile is native to kde, I had to manually set it to open pdfs and dvis on evince instead of okular. Now, last time I played around with LaTeX I was using TeXnic center on windows, and it had a very neat feature. Whenever I hit "QuickBuild", not only would it open the output .dvi file, but it would also show me exactly the piece of text I was editing. That is, if I were editing line 13 of the 7th of my document, when I compiled it, the dvi viewer would automatically take me to line 13 on the 7th page of the document, so I wouldn't have to scroll all the way down to it every time I compiled the .tex file. I'm guessing this is a pretty standard feature, and kile probably supports it. But since I don't know what it's called, I'm trying to be clear as to what I'm talking about. Problem is, this feature is not working for me right now, and I'm guessing it's either because evince does not support it, or because I have to manually configure it. Which one is it? And how do I manually configure it, if that's the case?

• How can I set Vim to obey accents of my spoken language?

  - by naxa

  When pressing w or e in sentences with accents (written in my native language), such as the first one (marked **) here: **Éj-mélybol fölzengo** - csing-ling-ling - száncsengo. Száncsengo - csing-ling-ling - tél csendjén halkan ring. [1] the characters o, ö, among others [2], make my gVim think they are word-ends so it stops on them (in Normal mode). gVim stops on the positions marked with _ where it shouldn't: Éj-mélyb_ol f_ölzeng_o. I would like to set gVim so it properly handle words even when containing accents and other local characters. But where do I set this? I use it on Win32, vim v 7.3.46.

• SSH traffic over openvpn connection freezes when I cat a file

  - by user42055

  I have an openvpn (version 2.1_rc15 at both ends) connection setup between two gentoo boxes using shared keys. it works fine for the most part. I use mysql, http, ftp, scp over the vpn with no problems. But when I ssh from the client to the server over the vpn, weird things happen. I can login, i can execute some commands. But if i try to run an ncurses application like top, or i try to cat a file, the connection will stall and I'll have to sever the ssh session. I can, for example, execute "echo blah; echo .; echo blah" and it will output the three lines of text over the ssh session fine. But if i execute "cat /etc/motd" the session will freeze the moment I press enter. I compiled openvpn 2.1.1 on my mac and copied over my config directory from my gentoo client. The mac connected and ssh sessions worked fine without freezing. I then compiled it on my older gentoo box (2.6.26 kernel) which I am retiring due to a dying hard drive, and ssh over it also works perfectly. Why does it fail on my brand new gentoo box ? I've tried compiling three different kernels in case it was that, but other than that there should be no difference between my older and my newer gentoo boxes that I can think of. Any suggestions on what's wrong ?

• Enabling mod_wsgi in Apache for a Django app on Gentoo

  - by hobbes3

  I installed Apache, Django, and mod_wsgi on Gentoo using emerge (on Amazon EC2). I know that the mod_wsgi is configured in /etc/apache2/modules.d/70_mod_wsgi.conf: <IfDefine WSGI> LoadModule wsgi_module modules/mod_wsgi.so </IfDefine> # vim: ts=4 filetype=apache So in my /etc/conf.d/apache I added the WSGI module: APACHE2_OPTS="-D DEFAULT_VHOST -D INFO -D SSL -D SSL_DEFAULT_VHOST -D LANGUAGE -D WSGI" But when I try to list the loaded module, mod_wsgi isn't listed. root ~ # apache2 -M | grep wsgi Syntax OK I also know that mod_wsgi isn't loading properly because the Apache configuration file doesn't recognize WSGIScriptAlias. By the way for Django to work I need to include a custom Apache configuration file. Where should I insert the line below? Include "/var/www/localhost/htdocs/mysite/apache/apache_django_wsgi.conf" I currently have that in the httpd.conf file but I feel like that file will get reseted whenever I upgrade Gentoo or related package. EDIT: it seems the mod_wsgi file is located in /usr/lib64/apache2/modules/mod_wsgi.so.

• Linux drivers for laser printer Konica Minolta Magicolor 4750DN

  - by user51166

  I would like to install the konica minolta magicolor 4750DN in Linux (debian 64 bits, I know it's not really supported but that's not the issue right now) but all the manual says is "put the CD rom in and copy the drivers and PPD file". However I did not get the CD ! On their "fantastic" internet site (...) there are only available drivers for Windows and Mac OSX. I tried to extract the ppd file from the .dmg file for MacOSX 10.7 but, if the PPD file works, a compiled file (only mac compiled, MACH 4 architectures says the "file" command) does not (obviously "cannot execute binary file", since I'm trying to run a Mac file on Linux). Is there anybody who has the same printer that could lend me the Linux drivers on the CD ROM ? Couldn't find them anywhere on the internet. Any way to execute a Mach (or BSD) binary file on Linux (I don't think is possible, although some "emulators" may exist). Thank you very much. I buyed this printer even because it was advertised as "Linux compatible", only to get this bad surprise. I would be grateful if you could help me solve this problem.

  - by jdg

  I have a new install of VIM from the automatic windows installer: gvim73_46.exe I have Python 2.7 (32 bit) installed. If I open gvim, and type: :set python? I get E518: Unknown option. If I try typing: :python 'hello' Vim crashes. What could be wrong? Here are the contents of :version in case they are helpful, although python is installed, and it is using Python 2.7. I also checked, and C:\Windows\System32\python27.dll is where it should be... I am really lost here. Does anyone have any ideas as to what is going wrong?

• Mutual piping on linux

  - by user21919

  I would like the output of A to be input for B and at the same time the output of B to be the input for A, is that possible? I tried the naïve thing: creating named pipes for A (pipeA) and B (pipeB) and then: pipeB | A | pipeA & pipeA | B | pipeB & But that does not work (pipeB is empty and switching the order would not help either). Any help would be appreciated. Example: Command A could be compiled form of this C program: #include <stdio.h> int main() { printf("0\n"); int x = 0; while (scanf("%d", &x) != EOF) { printf("%d\n", x + 1); } return 0; } Command B could be compiled form of this C program: #include <stdio.h> int main() { int x = 0; while (scanf("%d", &x) != EOF) { printf("%d\n", x + x); } return 0; }
