Name

CREATE DATABASE

Description

This statement is used to create a new database (database)

grammar:

CREATE DATABASE [IF NOT EXISTS] db_name
[PROPERTIES ("key"="value", ...)];

PROPERTIES Additional information about the database, which can be defaulted.

  • If you create an Iceberg database, you need to provide the following information in properties:

    PROPERTIES (
    "iceberg.database" = "iceberg_db_name",
    "iceberg.hive.metastore.uris" = "thrift://127.0.0.1:9083",
    "iceberg.catalog.type" = "HIVE_CATALOG"
    )

    illustrate:

    • ceberg.database : the library name corresponding to Iceberg;
    • iceberg.hive.metastore.uris : hive metastore service address;
    • iceberg.catalog.type: The default is HIVE_CATALOG; currently only HIVE_CATALOG is supported, and more Iceberg catalog types will be supported in the future.

Example

  1. Create a new database db_test

    CREATE DATABASE db_test;
  2. Create a new Iceberg database iceberg_test

    CREATE DATABASE `iceberg_test`
    PROPERTIES (
    "iceberg.database" = "doris",
    "iceberg.hive.metastore.uris" = "thrift://127.0.0.1:9083",
    "iceberg.catalog.type" = "HIVE_CATALOG"
    );
