CREATE DATABASE
CREATE DATABASE creates a new database.
Conceptual framework
Materialize mimics SQL standard’s namespace hierarchy, which is:
- Databases (highest level)
- Schemas
- Tables, views, sources
- Columns (lowest level)
Each layer in the hierarchy can contain elements directly beneath it. In this instance, databases can contain schemas.
For more information, see Namespaces.
Syntax
| Field | Use |
|---|---|
| IF NOT EXISTS | If specified, do not generate an error if a database of the same name already exists. If not specified, throw an error if a database of the same name already exists. (Default) |
| database_name | A name for the database. |
