Node.js is an event-based, non-blocking, asynchronous I/O framework that uses Google's V8 JavaScript engine. It is used for developing applications that make heavy use of the ability to run JavaScript both on the client, as well as on server side and therefore benefit from the re-usability of code...

UNION keyword in SQL is used to combine to SELECT statement results with out any duplicate. In order to use UNION and combine results both SELECT statement should have same number of column with same data type in same order, but the length of column can be different.
