# CREATE DATABASE

## Description

    This statement is used to create a new database  
    Syntax:  
        CREATE DATABASE [IF NOT EXISTS] db_name  
        [PROPERTIES ("key"="value", ...)] ;

1. PROPERTIES
    Additional information of a database, can be defaulted.
    1) In case of iceberg, the following information needs to be provided in the properties.
    ```
        PROPERTIES (
            "iceberg.database" = "iceberg_db_name",
            "iceberg.hive.metastore.uris" = "thrift://127.0.0.1:9083",
            "iceberg.catalog.type" = "HIVE_CATALOG"
            )

    ```
    `iceberg.database` is the name of the database corresponding to Iceberg.  
    `iceberg.hive.metastore.uris` is the address of the hive metastore service.  
    `iceberg.catalog.type` defaults to `HIVE_CATALOG`. Currently, only `HIVE_CATALOG` is supported, more Iceberg catalog types will be supported later.

## 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"
        );
        ```
