• How to search a MySQL database for a specific string

  - by Nadia

  I am trying to set up a search feature on my site that will only return exact matches to keyword entered by the user. So if the user searches "dog" I don't want an article titled "Doggy Style" to appear in the search results (just an example I don't really have an article by that name). This of course does exactly that: SELECT * FROM articles WHERE article_title LIKE '%$searchQuery%' $searchQuery here is a PHP variable taken from the user's input form. So is there any way to return only exact matches?

• Efficiently generate a 16-character, alphanumeric string

  - by ensnare

  I'm looking for a very quick way to generate an alphanumeric unique id for a primary key in a table. Would something like this work? def genKey(): hash = hashlib.md5(RANDOM_NUMBER).digest().encode("base64") alnum_hash = re.sub(r'[^a-zA-Z0-9]', "", hash) return alnum_hash[:16] What would be a good way to generate random numbers? If I base it on microtime, I have to account for the possibility of several calls of genKey() at the same time from different instances. Or is there a better way to do all this? Thanks.

• PHP equivalent to JavaScript's string split method

  - by m4k00

  I'm working with this on JavaScript: <script type="text/javascript"> var sURL = "http://itunes.apple.com/us/app/accenture-application-for/id415321306?uo=2&mt=8&uo=2"; splitURL = sURL.split('/'); var appID = splitURL[splitURL.length - 1].match(/[0-9]*[0-9]/)[0]; document.write('<br /><strong>Link Lookup:</strong> <a href="http://ax.itunes.apple.com/WebObjects/MZStoreServices.woa/wa/wsLookup?id=' + appID + '&country=es" >Lookup</a><br />'); </script> This script takes the numeric ID and gives me 415321306. So my question is how can I do the same thing but using PHP. Best regards.

• Ruby: backslash all non-alphanumeric characters in a string

  - by HBlend

  I have a script where I need to take a user's password and then run a command line using it. I need to backslash all (could be more then one) non-alphanumeric characters in the password. I have tried several things at this point including the below but getting no where. This has to be easy, just missing it. Tried these and several others: password = password.gsub(/(\W)/, '\\1') password = password.gsub(/(\W)/, '\\\1') password = password.gsub(/(\W)/, '\\\\1')

• Compressing a hex string in Ruby/Rails

  - by PreciousBodilyFluids

  I'm using MongoDB as a backend for a Rails app I'm building. Mongo, by default, generates 24-character hexadecimal ids for its records to make sharding easier, so my URLs wind up looking like: example.com/companies/4b3fc1400de0690bf2000001/employees/4b3ea6e30de0691552000001 Which is not very pretty. I'd like to stick to the Rails url conventions, but also leave these ids as they are in the database. I think a happy compromise would be to compress these hex ids to shorter collections using more characters, so they'd look something like: example.com/companies/3ewqkvr5nj/employees/9srbsjlb2r Then in my controller I'd reverse the compression, get the original hex id and use that to look up the record. My question is, what's the best way to convert these ids back and forth? I'd of course want them to be as short as possible, but also url-safe and simple to convert. Thanks!

• SQL Server Concatinate string column value to 5 char long

  - by mrp

  Scenario: I have a table1(col1 char(5)); A value in table1 may '001' or '01' or '1'. Requirement: Whatever value in col1, I need to retrive it in 5 char length concatenate with leading '0' to make it 5 char long. Technique I applied: select right(('00000' + col1),5) from table1; I didn't see any reason, why it doesn't work? but it didn't. Can anyone help me, how I can achieve the desired result?

• How to string multiple TextReaders together?

  - by Ken

  I have 3 TextReaders -- a combination of StreamReaders and StringReaders. Conceptually, the concatenation of them is a single text document. I want to call a method (not under my control) that takes a single TextReader. Is there any built-in or easy way to make a concatenating TextReader from multiple TextReaders? (I could write my own TextReader subclass, but it looks like a fair amount of work. In that case, I'd just write them all out to a temp file and then open it with a single StreamReader.) Is there an easy solution to this that I'm missing?

• Finding part of a string that a user has sent via POST

  - by blerh

  My users can send links from popular file hosts like Rapidshare, Megaupload, Hotfile and FileFactory. I need to somehow find out what filehost they sent the link from and use the correct class for it appropriately. For example, if I sent a Rapidshare link in a form on my web page, I need to somehow cycle through each file host that I allow until I find the text rapidshare.com, then I know the user has posted a Rapidshare link. Perhaps a PHP example: switch($_POST['link']) { case strstr($_POST['link'], 'rapidshare.com'): // the link is a Rapidshare one break; case strstr($_POST['link'], 'megaupload.com'): // the link is a Megaupload one break; case strstr($_POST['link'], 'hotfile.com'): // the link is a Hotfile one break; case strstr($_POST['link'], 'filefactory.com'): // the link is a Filefactory one break; } However, I know for a fact this isn't correct and I'd rather not use a huge IF statement if I can help it. Does anyone have any solution to this problem? If you need me to explain more I can try, English isn't my native language so it's kinda hard. Thanks all.

• Converting string to datetime

  - by duder

  I'm trying to enter a date in a mysql table `ssdate` datetime The function that produces the date can output it in 3 formats: 1276142400000 Thu Jun 10 00:00:00 GMT-0400 2010 Fri Jun 4 2010 I'm wondering which of these would be easiest to convert to this field format? Since I'm trying to save only the date, is there a better option than datetime that would work with one of these output formats?

  After reading a text file...

• How to compare a string with an option value

  - by user225269

  I have this html form which has options: <tr> <td width="30" height="35"><font size="3">*List:</td> <td width="30"><input name="specific" type="text" id="specific" maxlength="25" value=""> </td> <td><font size="3">*By:</td> <td> <select name="general" id="general"> <font size="3"> <option value="YEAR">Year</option> <option value="ADDRESS">Address</option> </select></td></td> </tr> And I'm trying to have this as the form action: if ('{$_POST["ADDRESS"]}'="ADDRESS") Which will compare if the value in the option in the html form matches the word "Address". If it matches then it will execute this query: $saddress= mysql_real_escape_string($_POST['specific']);<--this is the input form where the user will put the specific address to search. mysql_query("SELECT * FROM student WHERE ADDRESS='$saddress'"); Please I need help in here, I thinks its wrong: if ('{$_POST["ADDRESS"]}'="ADDRESS")

• String or binary data would be truncated -- Heisenberg problem

  - by harpo

  When you get this error, the first thing you ask is, which column? Unfortunately, SQL Server is no help here. So you start doing trial and error. Well, right now I have a statement like: INSERT tbl (A, B, C, D, E, F, G) SELECT A, B * 2, C, D, E, q.F, G FROM tbl ,othertable q WHERE etc etc Note that Some values are modified or linked in from another table, but most values are coming from the original table, so they can't really cause truncation going back to the same field (that I know of). Eliminating fields one at a time eventually makes the error go away, if I do it cumulatively, but — and here's the kicker — it doesn't matter which fields I eliminate. It's as if SQL Server is objecting to the total length of the row, which I doubt, since there are only about 40 fields in all, and nothing large. Anyone ever seen this before? Thanks. UPDATE: I have also done "horizontal" testing, by filtering out the SELECT, with much the same result. In other words, if I say WHERE id BETWEEN 1 AND 100: Error WHERE id BETWEEN 1 AND 50: No error WHERE id BETWEEN 50 AND 100: No error I tried many combinations, and it cannot be limited to a single row.

• Activator.CreateInstance with type name as string and including parameters

  - by Kelly

  I am working in .Net 3.5, looking at all the various constructors for Activator.CreateInstance. I want to create an instance of a class, calling a particular constructor. I do not have the class type, only its name. I have the following, which works, but actually winds up calling the parameterless constructor first, then the one I want. This is not a terribly big deal, but the parameterless constructor calls a rather busy base constructor, and the constructor I want to call does, too. In other words, given a type, calling CreateInstance with parameters is easy (only the last two lines below), but given only a type name, is there a better way than this? ObjectHandle oh = Activator.CreateInstance( "MyDllName", "MyNS." + "MyClassName" ); object o = oh.Unwrap( ); object newObj = Activator.CreateInstance( o.GetType( ), new object[] { param1 } ); return ( IMyDesiredObject )newObject; Thanks!
