reserved-words

问题 rails 2.3.4, sqlite3 I'm trying this Production.find(:all, :conditions => ["time > ?", start_time.utc], :order => "time DESC", :limit => 100) The condition works perfectly, but I'm having problems with the :order => time DESC . By chance, I discovered that it worked at Heroku (testing with heroku console), which runs PostgreSQL. However, locally, using sqlite3, new entries will be sorted after old ones, no matter what I set time to. Like this ( output has been manually stripped ): second

Closed 5 years ago . I know that I can just browse the web for these words but is there a way to just let Ruby do it for me? You don't have to give me a whole program, just some hints to let me go about it. Thanks in advance. 回答1: Well, you can always take a look at the ruby's source code: keywords. 回答2: You can't get

问题 After renaming my function the code stopped working. That new name scrollIntoView seems to be clashing with the element.scrollIntoView() method. <div onmousedown="scrollIntoView('id001')"/> function scrollIntoView(id) { alert(id); } I've created a simple test case https://jsfiddle.net/mgtn215y/ which has shown my function is simply ignored in favor of element.scrollIntoView() even it is not called on element attributes do not match The solution is obvious - to use a different function name.

问题 So I just spent what felt like an hour debugging why I was receiving a client-side 404 and a server-side System.Web.Http.HttpResponseException on System.Web.Http.dll!System.Web.Http.Dispatcher.DefaultHttpControllerSelector.SelectController(System.Net.Http.HttpRequestMessage request) + 0x33f byte ; no matter what I tried I could not get my ApiController derivative to receive requests. In the end, after trying to convert it to a regular Controller to no effect, it occurred to me to change the

问题 I need to Escape a reserved word to use it as an identifier in Delphi. I thought that was accomplished by using the ampersand "&", but that doesn't seem to be working right. Any other suggestions? 回答1: I found the doc page (search for Extended Syntax ) on it, and it should be ampersand. Figured out the problem. The ampersand works for compiling and error insight, but not code completion. Good to know. I had to add an _ suffix to get code completion to work, then change it back afterwords. I

问题 I have the following code in controllers/list.php: <?php class List extends Controller { function index() { echo "hi"; } } ?> However, trying to access it gives me the following PHP error: Parse error : syntax error, unexpected T_LIST, expecting T_STRING in /var/www/sitename/htdocs/system/application/controllers/list.php on line 3 Renaming the file to "example.php" and replacing "class List" with "class Example" works perfectly fine... my first thought was maybe "List" was a reserved name,

问题 I need to validate the Name of a SQL column, which is created programmatically... There whould be 2 validation rules: The Name shouldn't be a C# keyword The Name shouldn't be a SQL keyword (SQL Server 2008 R2) The solution for 1st rule it's nice: The CSharpCodeProvider class has the IsValidIdentifier method which makes the implementation of validation easy. (ex: string myColumnName = "blabla"; var isValid = _cSharpCodeProvider.IsValidIdentifier(myColumnName); ) The solution for 2nd rule it's

问题 I've been working on a personal project and have the below code in a new class that I have created: @property (readonly, getter = isFriend) BOOL friend; There doesn't seem to be anything wrong with it and when I build it, it works compiles absolutely fine but when we look at this line of code in the xcode IDE it looks like My question is why does the xcode IDE seem to think that the word friend is a keyword/reserved-word? 回答1: Presumably because friend is a reserved word in C++.
