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

Create a new database db_test
```
CREATE DATABASE db_test;
```

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"
);
