我傻眼了,这个问题还没有被有意义地问过.如何在SQL中创建等效函数,LTRIM或仅RTRIM用于回车和换行,仅在字符串的开头或结尾处.
显然REPLACE(REPLACE(@MyString,char(10),''),char(13),'')删除所有回车和新换行.这不是我想要的.我只是想删除前导或尾随的.
首先,这不是重复:为什么谷歌搜索通过谷歌api返回不同的结果到网页搜索？也没有任何其他"谷歌搜索API返回意外结果"的问题,我已经能够找到.
我正在编写一个使用Google网络搜索API的小型JavaScript程序.我正在为我的购买页面创建自定义链接,该页面应该引导用户访问我们经销商网站上的正确页面,以便在他们点击"购买地点"时购买他们上次查看的产品.我使用document.referrer的javascript方法,然后解析URL以确定用户上次访问我网站上的哪个页面.
然后我创建一个合适的查询字符串,将网站限制为特定的经销商,告诉谷歌只返回一个结果然后运行查询.然后我使用URL将特定div href中的HTML重写为第一个(也是唯一的)搜索结果.我基本上模仿了Google曾经拥有的"我感觉很幸运"按钮的功能,但是以这样的方式构建查询,以便我得到我正在寻找的结果.
好的,所以既然你知道我在做什么以及为什么我这样做,这就是事情变得奇怪的事情:我得到的大部分结果都很完美.他们返回第一个搜索结果.其中一些(和它总是相同的)返回第二个搜索结果.
以下是您可以自行复制并粘贴到Code Playground的代码,以查看我所指的问题:
