Package database is an auto-generated package for the Cloud Spanner API.
Cloud Spanner is a managed, mission-critical, globally consistent and scalable relational database service.
Example usage
To get started with this package, create a client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := database.NewDatabaseAdminClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close()
The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.
Using the Client
The following is an example of making an API call with the newly created client.
ctx := context.Background() // This snippet has been automatically generated and should be regarded as a code template only. // It will require modifications to work: // - It may require correct/in-range values for request initialization. // - It may require specifying regional endpoints when creating the service client as shown in: // https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options c, err := database.NewDatabaseAdminClient(ctx) if err != nil { // TODO: Handle error. } defer c.Close() req := &databasepb.ListDatabasesRequest{ // TODO: Fill request struct fields. // See https://pkg.go.dev/cloud.google.com/go/spanner/admin/database/apiv1/databasepb#ListDatabasesRequest. } it := c.ListDatabases(ctx, req) for { resp, err := it.Next() if err == iterator.Done { break } if err != nil { // TODO: Handle error. } // TODO: Use resp. _ = resp }
Use of Context
The ctx passed to NewDatabaseAdminClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.
To close the open connection, use the Close() method.

BackupIterator
type BackupIterator struct {
// Response is the raw response for the current page.
// It must be cast to the RPC response type.
// Calling Next() or InternalFetch() updates this value.
Response interface{}
// InternalFetch is for use by the Google Cloud Libraries only.
// It is not part of the stable interface of this package.
//
// InternalFetch returns results from a single call to the underlying RPC.
// The number of results is no greater than pageSize.
// If there are no more results, nextPageToken is empty and err is nil.
InternalFetch func(pageSize int, pageToken string) (results []*databasepb.Backup, nextPageToken string, err error)
// contains filtered or unexported fields
}
BackupIterator manages a stream of *databasepb.Backup.
func (*BackupIterator) Next
func (it *BackupIterator) Next() (*databasepb.Backup, error)
Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

Poll also fetches the latest metadata, which can be retrieved by Metadata.
If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.
