As mentioned in Basics, the term
database is mapped to
schema in Polypheny. To select a database, the following command can be used:
If the database does not already exist, it gets created automatically.
Similarly, to generate a collection the following command can be used:
db.createCollection( <name>, <options> )
If the collection already exists this command is a no-op.
To generate a new view the following syntax is used, if the collection does not exist an error is thrown:
db.createView( <view>, <source>, <pipeline>, <options> )
The following command removes the complete database, so it should be used with care:
To drop a specific collection and all its content the following command is used:
db.collection.drop( <options> )
To rename a collection use the following command:
db.collection.renameCollection( <target>, <dropTarget> )
