hyphen

My question is related to this one . except that my question is more sepcific as it is about whether a hyphen can be used in a query string parameter value. I am parsing $_SERVER['QUERY_STRING'] with PHP. I would like to know whether it is syntactically correct to use hyphens in query string values such as in the following case, or whether hyphens must be escaped in the browser URL. What about underscores? http://example.com/?q1=query-string-value-one&q2=query-string-value-two According to this document hyphens should be OK in all standards-compliant browsers, but I wanted to double check.

I have two strings - each string has many lines like the following: value_1 = "DEFAULT-VLAN" value_2 = "WAN" data = "HOSTNAME = DEFAULT-VLAN" result = string.gsub(data,value_1,value_2) print(result) Result: data = "HOSTNAME = DEFAULT-VLAN" When the hyphen ("-") is deleted from the value it is working. Is there an easy way to solve this? Thanks! - is a magic character in Lua patterns. You need to escape it. Change value_1 = "DEFAULT-VLAN" to: value_1 = "DEFAULT%-VLAN" This is because string.gsub takes a pattern similar to Regex—it does not do a "literal" replacement; this means you need to

I have keywords like "some-or-other" where the hyphens matter in the search through my mysql database. I'm currently using the fulltext function. Is there a way to escape the hyphen character? I know that one option is to comment out #define HYPHEN_IS_DELIM in the myisam/ftdefs.h file, but unfortunately my host does not allow this. Is there another option out there? Edit 3-8-11 Here's the code I have right now: $search_input = $_GET['search_input']; $keyword_safe = mysql_real_escape_string($search_input); $keyword_safe_fix = "*'\"" . $keyword_safe . "\"'*"; $sql = " SELECT *, MATCH(coln1,

Is there a way to easily sort in SQL Server 2005 while ignoring hyphens in a string field? Currently I have to do a REPLACE(fieldname,'-','') or a function to remove the hyphen in the sort clause. I was hoping there was a flag I could set at the top of the stored procedure or something. Access and the GridView default sorting seems to ignore the hypen in strings. I learned something new, just like you as well I believe the difference is between a " String Sort " vs a " Word Sort " (ignores hyphen) Sample difference between WORD sort and STRING sort http://andrusdevelopment.blogspot.com/2007/10

I want to import foo-bar.py. This works: foobar = __import__("foo-bar") This does not: from "foo-bar" import * My question: Is there any way that I can use the above format i.e., from "foo-bar" import * to import a module that has a - in it? you can't. foo-bar is not an identifier. rename the file to foo_bar.py Edit: If import is not your goal (as in: you don't care what happens with sys.modules , you don't need it to import itself), just getting all of the file's globals into your own scope, you can use execfile # contents of foo-bar.py baz = 'quux' >>> execfile('foo-bar.py') >>> baz 'quux' >

May be this question has been answered before but I couldn't find it. I am using a 2/3 yr old MySQL database which has hyphens in its column names. When I try to use these names from my Java code, the names are broken at the hyphen (e.g. air_port becomes air) and thus are not found. I tried replacing hyphens to underscores in my code hoping that the DB might treat them equally but that doesn't work. How can I escape the hyphen or how can I access these columns ? Could this be an issue of the character set being used ? enclose the names within `back-ticks` Do you have hyphens (-) or underscores
