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.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

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.CopyBackupRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/spanner/admin/database/apiv1/databasepb#CopyBackupRequest.
}
op, err := c.CopyBackup(ctx, req)
if err != nil {
	// TODO: Handle error.
}

resp, err := op.Wait(ctx)
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.

Types

type BackupIterator added in v1.3.0 

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)

RestoreDatabase create a new database by restoring from a completed backup. The new database must be in the same project and in an instance with the same instance configuration as the instance containing the backup. The returned database [long-running operation][google.longrunning.Operation] has a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id>, and can be used to track the progress of the operation, and to cancel it. The metadata field type is RestoreDatabaseMetadata. The response type is Database, if successful. Cancelling the returned operation will stop the restore and delete the database. There can be only one database being restored into an instance at a time. Once the restore operation completes, a new restore operation can be initiated, without waiting for the optimize operation associated with the first restore to complete.

func (*DatabaseAdminClient) UpdateDatabase added in v1.46.0 

func (c *DatabaseAdminClient) UpdateDatabase(ctx context.Context, req *databasepb.UpdateDatabaseRequest, opts ...gax.CallOption) (*UpdateDatabaseOperation, error)

UpdateDatabase updates a Cloud Spanner database. The returned [long-running operation][google.longrunning.Operation] can be used to track the progress of updating the database. If the named database does not exist, returns NOT_FOUND.

While the operation is pending: 

The database’s
reconciling
field is set to true.

Cancelling the operation is best-effort. If the cancellation succeeds,
the operation metadata’s
cancel_time
is set, the updates are reverted, and the operation terminates with a
CANCELLED status.

New UpdateDatabase requests will return a FAILED_PRECONDITION error
until the pending operation is done (returns successfully or with
error).

Reading the database via the API continues to give the pre-request
values.

Upon completion of the returned operation: 

The new values are in effect and readable via the API.

The database’s
reconciling
field becomes false.

The returned [long-running operation][google.longrunning.Operation] will have a name of the format projects/<project>/instances/<instance>/databases/<database>/operations/<operation_id> and can be used to track the database modification. The metadata field type is UpdateDatabaseMetadata. The response field type is Database, if successful.

Example 
package main

import (
	"context"

	database "cloud.google.com/go/spanner/admin/database/apiv1"

	databasepb "cloud.google.com/go/spanner/admin/database/apiv1/databasepb"
)

	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.UpdateDatabaseRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/spanner/admin/database/apiv1/databasepb#UpdateDatabaseRequest.
	}
	op, err := c.UpdateDatabase(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}

	resp, err := op.Wait(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*DatabaseAdminClient) UpdateDatabaseDdl 

func (c *DatabaseAdminClient) UpdateDatabaseDdl(ctx context.Context, req *databasepb.UpdateDatabaseDdlRequest, opts ...gax.CallOption) (*UpdateDatabaseDdlOperation, error)

UpdateDatabaseDdl updates the schema of a Cloud Spanner database by creating/altering/dropping tables, columns, indexes, etc. The returned [long-running operation][google.longrunning.Operation] will have a name of the format <database_name>/operations/<operation_id> and can be used to track execution of the schema change(s). The metadata field type is UpdateDatabaseDdlMetadata. The operation has no response.
