MySQL Drop Index

Last Updated: 25 June, 2023

To drop an index in MySQL, we can use the DROP INDEX statement.

Here's the syntax:

 DROP INDEX index_name ON table_name;

Replace index_name with the name of the index we want to drop, and table_name with the name of the table where the index is defined.

For example,

if we have an index called idx_customer_email defined on a table called customers, we can drop it using the following command:

  DROP INDEX idx_customer_email ON customers;

Make sure we have the necessary privileges to modify the table structure. Dropping an index can affect the performance of our queries, so be cautious and consider the impact before removing any indexes.

Note: Dropping an index removes it from the table, but it doesn't delete the data stored in the table.
