Drop Multiple Tables In Hive

Using a Script

If you have a large number of tables to drop, it may be more convenient to write a script to automate the process. You can create a script that loops through a list of table names and executes the DROP TABLE statement for each table. Here’s an example of a script that drops three tables, table1, table2, and table3:

#!/bin/bash


tables=("table1" "table2" "table3")

for table in "$tables[@]" do hive -e "DROP TABLE $table;" done

Running the script will drop all three tables in Hive without having to manually type out the DROP TABLE statement for each table.

Conclusion

Dropping multiple tables in Hive can be done efficiently using either the DROP TABLE statement or a script to automate the process. Whether you have a few tables to delete or a large number, these methods make it easy to clean up your Hive environment and manage your tables effectively.
