CreateDatabaseCommand

case class CreateDatabaseCommand(databaseName: String, ifNotExists: Boolean, path: Option[String], comment: Option[String], props: Map[String, String]) extends LogicalPlan with RunnableCommand with Product with Serializable

A command for users to create a new database.

It will issue an error message when the database with the same name already exists, unless 'ifNotExists' is true. The syntax of using this command in SQL is:

CREATE (DATABASE|SCHEMA) [IF NOT EXISTS] database_name
  [COMMENT database_comment]
  [LOCATION database_directory]
  [WITH DBPROPERTIES (property_name=property_value, ...)];
