Hey,

The following examples are simple, common data access queries that work on Hive as well as most SQL compatible RDBMS.

  • Syntax:
SELECT * FROM table;

Retrieves all columns from all rows from a table.

  • Similarly aggregations with GROUP BY and ordering of results are supported as expected,

SELECT col1, col2 FROM table GROUP BY col1, col2 ORDER BY col2 DESC;

These examples show how easy it is for anyone with SQL knowledge to log into a Hive command.
