Hive CRUD Operations Guide

Hive is a data warehouse tool that allows you to manipulate data using HiveQL, a language similar to SQL. Here are some common methods for adding, deleting, updating, and querying data in Hive.

1. Add (INSERT) data: Insert data into a table using the INSERT INTO statement.

INSERT INTO table_name (column1, column2, ...)
VALUES (value1, value2, ...);

1. Delete data: Use the DELETE FROM statement to remove data from a table.

DELETE FROM table_name WHERE condition;

1. Update data: Use the UPDATE statement to update data in a table.

UPDATE table_name SET column1 = value1, column2 = value2 WHERE condition;

1. Retrieve data from a table using the SELECT statement.

SELECT column1, column2, ... FROM table_name WHERE condition;

These are commonly used CRUD operations in Hive, and you can choose the appropriate method based on your specific needs and data operations.
