To create a database in Hive and switch to it, you can use the following commands:
- Creating a database:
CREATE DATABASE database_name;
Replace database_name with the name you want to give your database. This command will create a new database in Hive.
- Switching to a database:
USE database_name;
Replace database_name with the name of the database you want to switch to. This command will set the specified database as the current database in Hive.
Once you have switched to a database, any subsequent Hive commands you run will be executed in the context of that database. For example, if you run the command SHOW TABLES; after switching to a database, you will see a list of tables that belong to that database.
