Use Case When a user goes to my website, they will be confronted with a search box much like SO. They can search for results using plan text. ".net questions", "closed questions", ".net and java", etc.. The search will function a bit different that SO, in that it will try to as much as possible of the schema of the database rather than a straight fulltext search. So ".net questions" will only search for .net questions as opposed to .net answers (probably not applicable to SO case, just an example here), "closed questions" will return questions that are closed, ".net and java" questions will

There are a lot of questions at this site with the problems while compiling c++ template code. One of the most common solutions to such problems is to add typename (and, less frequently, template ) keyword in the right places of the program code: template<typename T> class Base { public: typedef char SomeType; template<typename U> void SomeMethod(SomeType& v) { // ... } }; template<typename T> class Derived : public Base<T> { public: void Method() { typename Base<T>::SomeType x; // ^^^^^^^^ this->template SomeMethod<int>(x); // ^^^^^^^^ } }; Whether there is a code that compiles both with and

Is null is a keyword in Java? Warrior No.It is not a keyword. Jon Skeet Not according to the Java Language Specification list of keywords . On the other hand, this doesn't compile: int null = 10; The rules for identifiers specify that: An identifier is an unlimited-length sequence of Java letters and Java digits, the first of which must be a Java letter. An identifier cannot have the same spelling (Unicode character sequence) as a keyword (§3.9), boolean literal (§3.10.3), or the null literal (§3.10.7). I'm not sure what the benefit of making it not-a-keyword is, to be honest. Marc Gravell Not

This code does not compile for me on gcc version 4.3.2 (Debian 4.3.2-1.1) main(){ int unix; } I've checked the C keywords list and "unix" is not one of them. Why am I getting the following error? unix.c:2: error: expected identifier or ‘(’ before numeric constant Anybody? pmg unix is not a identifier reserved by the Standard. If you compile with -std=c89 or -std=c99 the gcc compiler will accept the program as you expected. From gcc manual ( https://gcc.gnu.org/onlinedocs/cpp/System-specific-Predefined-Macros.html ), the emphasis is mine. ... However, historically system-specific macros have

Is there any rule for the SQLite's column name? Can it have characters like '/'? Can it be UTF-8? http://www.sqlite.org/lang_keywords.html that has a complete list! enjoy! J. Polfer Can it have characters like '/'? All examples are from SQlite 3.5.9 running on Linux. If you surround the column name in double quotes, you can: > CREATE TABLE test_forward ( /test_column INTEGER ); SQL error: near "/": syntax error > CREATE TABLE test_forward ("/test_column" INTEGER ); > INSERT INTO test_forward("/test_column") VALUES (1); > SELECT test_forward."/test_column" from test_forward; 1 That said, you
