How to escape underscore character in PATINDEX pattern argument?

由 坚强是说给别人听的谎言 提交于 2019-11-29 22:37:34
I've found a solution for finding the position of an underscore with PATINDEX : DECLARE @a VARCHAR(10) SET @a = '37_21' PRINT PATINDEX('%_%', @a) -- return 1 (false) PRINT PATINDEX('%!%', REPLACE(@a, '_', '!')) -- return 3 (correct) Have you other ideas? Like a way to escape the underscore character? Curt Hagenlocher I've always done it with brackets: '%[_]%' To match two underscores, each must be bracketed '%[__]%' -- matches single _ with anything after '%[_][_]%' -- matches two consecutive _ Charlie You can escape using the [ and ] characters like so: PRINT PATINDEX('%[_]%', '37_21') 来源：

Escaping the '\' character in the replacement string in a sed expression

由 爷，独闯天下 提交于 2019-11-29 20:35:33
问题 I am trying to take a line of text like 13) Check for orphaned Path entries and change it to (I want the bash color codes to colorize the output, not display on the screen) \033[32m*\033[0m Check for orphaned Path entries with bash color codes to colorize the asterisk to make it stand out more. I have a sed command that does most of that, except it doesn't handle the color codes correctly since it sees them as references to replacement text. What I have so far: sed "s/ *13) \(.*\)/ \033[32m*

Spaces in java execute path for OS X

由 扶醉桌前 提交于 2019-11-29 18:31:12
问题 On OS X, I am trying to .exec something, but when a path contains a space, it doesn't work. I've tried surrounding the path with quotes, escaping the space, and even using \u0020. For example, this works: Runtime.getRuntime().exec("open /foldername/toast.sh"); But if there's a space, none of these work: Runtime.getRuntime().exec("open /folder name/toast.sh"); Runtime.getRuntime().exec("open \"/folder name/toast.sh\""); Runtime.getRuntime().exec("open /folder\\ name/toast.sh"); Runtime

Default escaping in Freemarker

由 三世轮回 提交于 2019-11-29 18:12:01
问题 In Freemarker templates we can use the escape directive to automatically apply an escaping to all interpolations inside the included block: <#escape x as x?html> <#-- name is escaped as html --> Hallo, ${name} </#escape> Is there a way to programmatically achieve a similar effect, defining a default escape applied to all interpolations in the template, including those outside escape directives? Thanks. 回答1: To elaborate on Attila's answer: you can use a class like this one and then wrap your

htaccess rewrite rule with escaped ampersand in $_GET fails

由 时间秒杀一切 提交于 2019-11-29 17:31:11
问题 I am encountering a problem with a get parameter in conjunction with a htaccess rewrite rule. Below is the urlencode()'ed link; the rewrite rule I use to redirect to index.php, and lastly, a print_r($_GET) on the index.php. As you can see, the urlescaped ampersand is not part of the value for variable static, but instead and contrary to my expectation gets interpreted as a variable seperator. Why? Initial link: <a href="static/Game-Tech-%26-Arts-Lab">link</a> .htaccess: RewriteRule ^static/(.
