How to rename a table in Hive?

 In Hive, you can rename a table using the ALTER TABLE command. Here's the syntax for renaming a table:

css
ALTER TABLE table_name RENAME TO new_table_name;

Replace table_name with the current name of the table you want to rename, and replace new_table_name with the new name you want to give the table.

Here's an example code snippet:

sql
-- Create a table called my_table
CREATE TABLE my_table (
  id INT,
  name STRING
);

-- Rename the table to new_table
ALTER TABLE my_table RENAME TO new_table;

In this code, we first create a table called my_table with two columns, id and name. Then, we use the ALTER TABLE command to rename the table to new_table.

Note that when you rename a table, Hive only changes the metadata associated with the table. The data stored in the table is not affected by the rename operation.
