--- slug: /create-database-of-api --- # create_database - Create a database The `create_database()` function is used to create a new database. :::info * This interface can only be used when you are connected to the database using `AdminClient`. For more information about `AdminClient`, see [Admin Client](../100.admin-client.md). * Currently, when you use `create_database` to create a database, you cannot specify the database properties. The database will be created based on the default values of the properties. If you want to create a database with specific properties, you can try to create it using SQL. For more information about how to create a database using SQL, see [Create a database](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000003977077). ::: ## Prerequisites * You have installed pyseekdb. For more information about how to install pyseekdb, see [Get Started](../../10.pyseekdb-sdk/10.pyseekdb-sdk-get-started.md). * You are connected to the database. For more information about how to connect to the database, see [Admin Client](../100.admin-client.md). * If you are using server mode of seekdb or OceanBase Database, make sure that the connected user has the `CREATE` privilege. For more information about how to check the privileges of the current user, see [View user privileges](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000003980135). If the user does not have this privilege, contact the administrator to grant it. For more information about how to directly grant privileges, see [Directly grant privileges](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000003980140). ## Limitations * In a seekdb instance or OceanBase Database, the name of each database must be globally unique. * The maximum length of a database name is 128 characters. * The name can contain only uppercase and lowercase letters, digits, underscores, dollar signs, and Chinese characters. * Avoid using reserved keywords as database names. For more information about reserved keywords, see [Reserved keywords](https://www.oceanbase.com/docs/common-oceanbase-database-cn-1000000003976774). ## Recommendations * We recommend that you give the database a meaningful name that reflects its purpose and content. For example, you can use `Application Identifier_Sub-application name (optional)_db` as the database name. * We recommend that you create the database and related users using the root user and assign only the necessary privileges to ensure the security and controllability of the database. * You can create a database with a name consisting only of digits by enclosing the name in backticks (`), but this is not recommended. This is because names consisting only of digits have no clear meaning, and queries require the use of backticks (`), which can lead to unnecessary complexity and confusion. ## Request parameters ```python create_database(name, tenant=DEFAULT_TENANT) ``` |Parameter|Type|Required|Description|Example value| |---|---|---|---|---| |`name`|string|Yes|The name of the database to be created. |`my_database`| |`tenant`|string|No
