To run a flink program from your IDE(we can use either Eclipse or Intellij IDEA(preffered)), you need two dependencies:flink-java / flink-scala and flink-clients (as of february 2016). These JARS can be added using Maven and SBT(if you are using scala). Maven <dependency> <group...
This example is the same as WordCount, but uses the Table API. See WordCount for details about execution and results. Maven To use the Table API, add flink-table as a maven dependency: <dependency> <groupId>org.apache.flink</groupId> <artifactId>flink-table_2.11&...
Maven Add the dependencies flink-java and flink-client (as explained in the JVM environment setup example). The code public class WordCount{ public static void main( String[] args ) throws Exception{ // set up the execution environment final ExecutionEnvironment env = E...

Once the sports2000 database has been installed it's time to run it as a standalone server (and not connect to it as a file). Start proenv (proenv in the startmeny on Windows or /usr/install-directory/bin/proenv on Linux/Unix). This example is from Windows. Linux is the same but you need to change...
Unlike other languages, Python doesn't have a do-until or a do-while construct (this will allow code to be executed once before the condition is tested). However, you can combine a while True with a break to achieve the same purpose. a = 10 while True: a = a-1 print(a) if a<7: ...
