The dropIndex Change Type drops an existing index on a column.


You can typically use the dropIndex Change Type when you want to remove the specific index that identifies records in your database.

Once an index has been dropped, all metadata is removed. The index can’t be rebuilt and you must create it again. Also, if you drop a clustered index, the table will lose its identifiers.

Running the dropIndex Change Type

To drop an existing index in your database, follow these steps:

  1. Add the dropIndex Change Type to your changeset with the needed attributes as it is shown in the examples.
  2. Deploy your changeset by running the update command:
  3. liquibase update
