Examples of com.datastax.driver.core.Session.execute()

com.datastax.driver.core.Session.execute()
Executes the provided query. This is a convenience method for {@code execute(new SimpleStatement(query))}. @param query the CQL query to execute. @return the result of the query. That result will never be null but canbe empty (and will be for any non SELECT query). @throws NoHostAvailableException if no host in the cluster can becontacted successfully to execute this query. @throws QueryExecutionException if the query triggered an executionexception, i.e. an exception thrown by Cassandra when it cannot execute the query with the requested consistency level successfully. @throws QueryValidationException if the query if invalid (syntax error,unauthorized or any other validation problem).
