Tarik When you write an implementation file (.cpp, .cxx, etc) your compiler generates a translation unit. This is the source file from your implementation plus all the headers you #included in it. Internal linkage refers to everything only in scope of a translation unit. External linkage refers to things that exist beyond a particular translation unit. … Read more
UPDATE R SET R.status=”0″ FROM dbo.ProductReviews AS R INNER JOIN dbo.products AS P ON R.pid = P.id WHERE R.id = ‘17190’ AND P.shopkeeper=”89137″;
In computer science terms, a Task is a future or a promise. (Some people use those two terms synonymously, some use them differently, nobody can agree on a precise definition.) Basically, a Task<T> “promises” to return you a T, but not right now honey, I’m kinda busy, why don’t you come back later? A Thread … Read more
What you have should work. If, however, the spaces provided are defaulting to… something else? You can use the whitespace regex: str = “Hello I’m your String”; String[] splited = str.split(“\\s+”); This will cause any number of consecutive spaces to split your string into tokens.
I thought this might be useful: There are three places where the timezone might be set in MySQL: In the file “my.cnf” in the [mysqld] section default-time-zone=”+00:00″ @@global.time_zone variable To see what value they are set to: SELECT @@global.time_zone; To set a value for it use either one: SET GLOBAL time_zone=”+8:00″; SET GLOBAL time_zone=”Europe/Helsinki”; SET … Read more
You also have the shortcut option of Dir[“/path/to/search/*”] and if you want to find all Ruby files in any folder or sub-folder: Dir[“/path/to/search/**/*.rb”]

That is allowed by default on MySQL. What is disabled by default is remote root access. If you want to enable that, run this SQL command locally: GRANT ALL PRIVILEGES ON *.* TO ‘root’@’%’ IDENTIFIED BY ‘password’ WITH GRANT OPTION; FLUSH PRIVILEGES; And then find the following line and comment it out in your my.cnf … Read more
Thanks to Dart’s factory constructors, it’s easy to build a singleton: class Singleton { static final Singleton _singleton = Singleton._internal(); factory Singleton() { return _singleton; } Singleton._internal(); } You can construct it like this main() { var s1 = Singleton(); var s2 = Singleton(); print(identical(s1, s2)); // true print(s1 == s2); // true }
There is no combination of LIKE & IN in SQL, much less in TSQL (SQL Server) or PLSQL (Oracle). Part of the reason for that is because Full Text Search (FTS) is the recommended alternative. Both Oracle and SQL Server FTS implementations support the CONTAINS keyword, but the syntax is still slightly different: Oracle: WHERE … Read more
