35 DATABASE

CREATE DATABASE

Creates a new database.

CREATE DATABASE [IF NOT EXISTS] db_name [ON CLUSTER cluster] [ENGINE = engine(...)]

Clauses

IF NOT EXISTS

If the db_name database already exists, then ClickHouse doesn’t create a new database and:

  • Doesn’t throw an exception if clause is specified.
  • Throws an exception if clause isn’t specified.

ON CLUSTER

ClickHouse creates the db_name database on all the servers of a specified cluster. More details in a Distributed DDL article.

ENGINE

MySQL allows you to retrieve data from the remote MySQL server. By default, ClickHouse uses its own database engine. There’s also a lazy engine.
