I made a route for it in the Global.asax: routes.MapPageRoute("article-browse", "article/{id}", "~/Article.aspx"); So the link consists of the article's id which is, obviously, not a very nice, nor SEO friendly link. I would like to display the Article's title in the link, instead of the ID. Do I have to pass the whole title in the parameter (instead of the id) and then make a SQL query

Is there any reason to prefer one way to the other? if (key in object) if (object.hasOwnProperty(key)) 回答1: Be careful - they won't produce the same result. in will also return true if key gets found somewhere in the prototype chain , whereas Object.hasOwnProperty (like the name already tells us), will only return true if key is available on that object directly (its "owns" the property). 回答2: I'l try to explain with another example. Say we have the following object with two properties

(I am using InnoDB so fulltext search not an option) 回答1: There's really no nice solution except concatenating ANDs: SELECT * FROM myTable WHERE title
