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.
