Hey,

The insert command is used to load the data Hive table. Inserts can be done to a table or a partition.

  • INSERT OVERWRITE:- This command is used to overwrite the existing data in the table or partition.
  • INSERT INTO:- This command is used to append the data into existing data in a table.
