PyOrient Client - db_drop()

This method removes a database from the connected OrientDB server.

Dropping Databases

In certain situations, you may want to remove a full database from the OrientDB Server. For instance, if you create a temporary database in memory for certain operations or if you want to provide the user with the ability to uninstall the database with the application, without removing OrientDB itself.

Syntax

client.db_drop(<db-name>)

• <db-name> Defines the database to remove.

Example

Consider the example of the smart home database. In developing your application, you may want to frequently reset the database to a clean state. This allows you to move forward with a new implementation without having to worry about an obsolete schema causing problems for you.

# Reset Database
def reset_db(client, name):

   # Remove Old Database
   client.db_drop(name)

   # Create New Database
   client.db_create(name, 
      pyorient.DB_TYPE_GRAPH, 
      pyorient.STORAGE_TYPE_PLOCAL)

Here, the function receives the client and the database name. It deletes the given database and creates a new one with the same name.
