# POST /v1/{+parent}/databases

`POST /v1/{+parent}/databases`

Creates a new Spanner database and starts to prepare it for serving. The returned long-running operation will have a name of the format `/operations/` and can be used to track preparation of the database. The metadata field type is CreateDatabaseMetadata. The response field type is Database, if successful.

## Path parameters

- `parent` string, required

## Request body

- CreateDatabaseRequest — The request for CreateDatabase.
  - `createStatement` 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 (`` ` ``).
  - `extraStatements` string[] — Optional. A 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.
  - `encryptionConfig` EncryptionConfig — Encryption configuration for a Cloud Spanner database.
    - `kmsKeyName` string — The Cloud KMS key to be used for encrypting and decrypting the database. Values are of the form `projects//locations//keyRings//cryptoKeys/`.
    - `kmsKeyNames` string[] — Specifies the KMS configuration for one or more keys used to encrypt the database. Values are of the form `projects//locations//keyRings//cryptoKeys/`. The keys referenced by `kms_key_names` must fully cover all regions of the database's instance configuration. Some examples: * For regional (single-region) instance configurations, specify a regional location KMS key. * For multi-region instance configurations of type `GOOGLE_MANAGED`, either specify a multi-region location KMS key or multiple regional location KMS keys that cover all regions in the instance configuration. * For an instance configuration of type `USER_MANAGED`, specify only regional location KMS keys to cover each region in the instance configuration. Multi-region location KMS keys aren't supported for `USER_MANAGED` type instance configurations.
  - `databaseDialect` 'DATABASE_DIALECT_UNSPECIFIED' | 'GOOGLE_STANDARD_SQL' | 'POSTGRESQL' — Optional. The dialect of the Cloud Spanner Database.
  - `protoDescriptors` string, byte — Optional. Proto descriptors used by `CREATE/ALTER PROTO BUNDLE` statements in 'extra_statements'. Contains a protobuf-serialized [`google.protobuf.FileDescriptorSet`](https://github.com/protocolbuffers/protobuf/blob/main/src/google/protobuf/descriptor.proto) descriptor set. To generate it, [install](https://grpc.io/docs/protoc-installation/) and run `protoc` with --include_imports and --descriptor_set_out. For example, to generate for moon/shot/app.proto, run ``` $protoc --proto_path=/app_path --proto_path=/lib_path \ --include_imports \ --descriptor_set_out=descriptors.data \ moon/shot/app.proto ``` For more details, see protobuffer [self description](https://developers.google.com/protocol-buffers/docs/techniques#self-description).
