<div class="method">
    <code class="details" id="create">create(parent, body, x__xgafv=None)</code>
  <pre>Creates a new Cloud Spanner database and starts to prepare it for serving.
The returned long-running operation will
have a name of the format `<database_name>/operations/<operation_id>` and
can be used to track preparation of the database. The
metadata field type is
CreateDatabaseMetadata. The
response field type is
Database, if successful.

Args:
  parent: string, Required. The name of the instance that will serve the new database.
Values are of the form `projects/<project>/instances/<instance>`. (required)
  body: object, The request body. (required)
    The object takes the form of:

{ # The request for CreateDatabase.
    "extraStatements": [ # An optional list of DDL statements to run inside the newly created
        # database. Statements can create tables, indexes, etc. These
        # statements execute atomically with the creation of the database:
        # if there is an error in any statement, the database is not created.
      "A String",
    ],
    "createStatement": "A String", # Required. A `CREATE DATABASE` statement, which specifies the ID of the
        # new database.  The database ID must conform to the regular expression
        # `a-z*[a-z0-9]` and be between 2 and 30 characters in length.
        # If the database ID is a reserved word or if it contains a hyphen, the
        # database ID must be enclosed in backticks (`` ` ``).

Returns:
  An object of the form:

    { # This resource represents a long-running operation that is the result of a
      # network API call.
    "metadata": { # Service-specific metadata associated with the operation.  It typically
        # contains progress information and common metadata such as create time.
        # Some services might not provide such metadata.  Any method that returns a
        # long-running operation should document the metadata type, if any.

        # available.
    "response": { # The normal response of the operation in case of success.  If the original
        # method returns no data on success, such as `Delete`, the response is
        # `google.protobuf.Empty`.  If the original method is standard
        # `Get`/`Create`/`Update`, the response should be the resource.  For other
        # methods, the response should have the type `XxxResponse`, where `Xxx`
        # is the original method name.  For example, if the original method name
        # is `TakeSnapshot()`, the inferred response type is
        # `TakeSnapshotResponse`.
      "a_key": "", # Properties of the object. Contains field @type with type URL.
    },
    "name": "A String", # The server-assigned name, which is only unique within the same service that
        # originally returns it. If you use the default HTTP mapping, the
        # `name` should have the format of `operations/some/unique/name`.
    "error": { # The `Status` type defines a logical error model that is suitable for different # The error result of the operation in case of failure or cancellation.
        # programming environments, including REST APIs and RPC APIs. It is used by
        # [gRPC](https://github.com/grpc). The error model is designed to be:
        #
        # - Simple to use and understand for most users
        # - Flexible enough to meet unexpected needs
        #
        # # Overview
        #
        # The `Status` message contains three pieces of data: error code, error message,
        # and error details. The error code should be an enum value of
        # google.rpc.Code, but it may accept additional error codes if needed.  The
        # error message should be a developer-facing English message that helps
        # developers *understand* and *resolve* the error. If a localized user-facing
        # error message is needed, put the localized message in the error details or
        # localize it in the client. The optional error details may contain arbitrary
        # information about the error. There is a predefined set of error detail types
        # in the package `google.rpc` which can be used for common error conditions.
        #
        # # Language mapping
        #
        # The `Status` message is the logical representation of the error model, but it
        # is not necessarily the actual wire format. When the `Status` message is
        # exposed in different client libraries and different wire protocols, it can be
        # mapped differently. For example, it will likely be mapped to some exceptions
        # in Java, but more likely mapped to some error codes in C.
        #
        # # Other uses
        #
        # The error model and the `Status` message can be used in a variety of
        # environments, either with or without APIs, to provide a
        # consistent developer experience across different environments.
        #
        # Example uses of this error model include:
        #
        # - Partial errors. If a service needs to return partial errors to the client,
        #     it may embed the `Status` in the normal response to indicate the partial
        #     errors.
        #
        # - Workflow errors. A typical workflow has multiple steps. Each step may
        #     have a `Status` message for error reporting purpose.
        #
        # - Batch operations. If a client uses batch request and batch response, the
        #     `Status` message should be used directly inside batch response, one for
        #     each error sub-response.
        #
        # - Asynchronous operations. If an API call embeds asynchronous operation
        #     results in its response, the status of those operations should be
        #     represented directly using the `Status` message.
        #
        # - Logging. If some API errors are stored in logs, the message `Status` could
        #     be used directly after any stripping needed for security/privacy reasons.
      "message": "A String", # A developer-facing error message, which should be in English. Any
          # user-facing error message should be localized and sent in the
          # google.rpc.Status.details field, or localized by the client.
      "code": 42, # The status code, which should be an enum value of google.rpc.Code.
      "details": [ # A list of messages that carry the error details.  There will be a
          # common set of message types for APIs to use.
        {
          "a_key": "", # Properties of the object. Contains field @type with type URL.

        #
        # - Simple to use and understand for most users
        # - Flexible enough to meet unexpected needs
        #
        # # Overview
        #
        # The `Status` message contains three pieces of data: error code, error message,
        # and error details. The error code should be an enum value of
        # google.rpc.Code, but it may accept additional error codes if needed.  The
        # error message should be a developer-facing English message that helps
        # developers *understand* and *resolve* the error. If a localized user-facing
        # error message is needed, put the localized message in the error details or
        # localize it in the client. The optional error details may contain arbitrary
        # information about the error. There is a predefined set of error detail types
        # in the package `google.rpc` which can be used for common error conditions.
        #
        # # Language mapping
        #
        # The `Status` message is the logical representation of the error model, but it
        # is not necessarily the actual wire format. When the `Status` message is
        # exposed in different client libraries and different wire protocols, it can be
        # mapped differently. For example, it will likely be mapped to some exceptions
        # in Java, but more likely mapped to some error codes in C.
        #
        # # Other uses
        #
        # The error model and the `Status` message can be used in a variety of
        # environments, either with or without APIs, to provide a
        # consistent developer experience across different environments.
        #
        # Example uses of this error model include:
        #
        # - Partial errors. If a service needs to return partial errors to the client,
        #     it may embed the `Status` in the normal response to indicate the partial
        #     errors.
        #
        # - Workflow errors. A typical workflow has multiple steps. Each step may
        #     have a `Status` message for error reporting purpose.
        #
        # - Batch operations. If a client uses batch request and batch response, the
        #     `Status` message should be used directly inside batch response, one for
        #     each error sub-response.
        #
        # - Asynchronous operations. If an API call embeds asynchronous operation
        #     results in its response, the status of those operations should be
        #     represented directly using the `Status` message.
        #
        # - Logging. If some API errors are stored in logs, the message `Status` could
        #     be used directly after any stripping needed for security/privacy reasons.
      "message": "A String", # A developer-facing error message, which should be in English. Any
          # user-facing error message should be localized and sent in the
