alias

I have a doubt and question regarding alias in sql. If i want to use the alias in same query can i use it. For eg: Consider Table name xyz with column a and b select (a/b) as temp , temp/5 from xyz Is this possible in some way ? You are talking about giving an identifier to an expression in a query and then reusing that identifier in other parts of the query? That is not possible in Microsoft SQL Server which nearly all of my SQL experience is limited to. But you can however do the following. SELECT temp, temp / 5 FROM ( SELECT (a/b) AS temp FROM xyz ) AS T1 Obviously that example isn't

So "cs" will be mapped to "/College/" so that I can run the command "cd cs"? I believe you are asking about how to create a symbolic link (or symlink) like: ln -s College cs Although, there are other ways to speed up your workflow, such as setting the CDPATH: export CDPATH=.:~/:/College/ Or you could even make "cs" an alias that will perform the action "cd /College/": alias cs='cd /College/' If you did the above, you would type cs instead of cd cs to get there. See also ln - man page for the ln command from the POSIX 2004 standard symlink - man page for the C function to create symlinks from

I have a reasonable number of nodes (roughly 60,000) (:Document {title:"A title"}) Given a title, I want to find the matching node, if it exists. The problem is that the title I'm given is not consistent. That is, sometimes the beginning of a new word is Capital, sometimes it is all lower case. Sometimes Key-Words are combined with Kebab case, sometimes they are written normally as key words. To compensate for that I use apoc and the Levenshtein distance between the given title and every node and only accept a node as a match if it is below some threshold: MATCH (a:Document) WHERE apoc.text

I just ran into this message: $ git add . warning: You ran 'git add' with neither '-A (--all)' or '--ignore-removal', whose behaviour will change in Git 2.0 with respect to paths you removed. Paths like 'README.md' that are removed from your working tree are ignored with this version of Git. * 'git add --ignore-removal <pathspec>', which is the current default, ignores paths you removed from your working tree. * 'git add --all <pathspec>' will let you also record the removals. Run 'git status' to check the paths you removed from your working tree. I think setting --all is a pretty sane default
