Deletes a database from a specified PolarDB cluster.

  • The cluster must be in the Running state and unlocked. Otherwise, the specified database cannot be deleted.
  • The delete operation is performed in an asynchronous manner. It may take a long time to delete a large database. A success response for this operation only indicates that the request to delete the database is sent. You must confirm that the database does not exist in the cluster to determine that the database has been deleted.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
