What is the query language used by Hive?

The query language for Hive is called HiveQL (Hive Query Language), which is similar to traditional SQL but also contains certain Hive-specific features and syntax and is used for querying and analyzing data within Apache Hive.

Using HiveQL, users can write SQL-like queries to retrieve, transform, and analyze data from Hive tables. HiveQL supports common SQL operations such as SELECT, WHERE, GROUP BY, ORDER BY, while also providing support for big data processing in the Hadoop ecosystem, such as MapReduce tasks, partitioned tables, storage formats, etc. Using HiveQL makes it convenient to leverage Hive for large-scale data processing and analysis.
