parentheses

Was wondering whether anyone would know why do we use the parentheses in this SQL: So, the format goes as follows: Name,location and department of the service of the employees whose name starts with A or B. (A rough translation from French). I answered the following way: SELECT service.nom_serv, localite.ville, localite.departemen FROM service, localite, employe WHERE service.code_loc=localite.code_loc AND employe.service=service.code_serv AND ((employe.nom LIKE 'A%') OR (employe.nom LIKE 'B%')) Basically, where the last AND is concerned for the WHERE, couldn't I simply do without the

How I can do custom Java annotation with no attribute name inside parentheses? I don't want this: @annotation_name(att=valor) . I just want like in Servlets, i.e: @WebServlet("/main") Define the annotation with an attribute named value , then the attribute name can be omitted: @interface CustomAnnotation { String value(); } This can be used like so: @CustomAnnotation("/main") // ...

I'm having a really tough time solving this problem with JavaScript You are given a string s that consists of English letters, punctuation marks, whitespace characters and brackets. It is guaranteed that the brackets in s form a regular bracket sequence. Your task is to reverse the strings in each pair of matching parenthesis, starting from the innermost one. Example For string "s = a(bc)de" the output should be reverseParentheses(s) = "acbde". Input/Output [time limit] 4000ms (js) [input] string s A string consisting of English letters, punctuation marks, whitespace characters and brackets.

I've been trying to make this work but to no avail I tried a few variations but I know it's a simple thing I'm missing and I don't want to go using Replace to achieve it. var item = "Brake(45X)" Regex searchTerm = new Regex(@"\((.*)\)"); var value = (searchTerm.Match(item).Groups.Count > 0) ? searchTerm.Match(item).Groups[0].Value : string.Empty; Some people accuse me of using zero width assertions all the

I have a simple question regarding the use of parentheses in Python conditional statements. The following two snippets works just the same but I wonder if this is only true because of it's simplicity; >>> import os, socket >>> if ((socket.gethostname() == "bristle") or (socket.gethostname() == "rete")): ...

DEBUG = False ... else: ... DEBUG = True ... >>> DEBUG Could anyone help shed some light on this? Are
