updateDatabaseDdl(String instanceId, String databaseId, Iterable<String> statements, String operationId)

public abstract OperationFuture<Void,UpdateDatabaseDdlMetadata> updateDatabaseDdl(String instanceId, String databaseId, Iterable<String> statements, String operationId)

Enqueues the given DDL statements to be applied, in order but not necessarily all at once, to the database schema at some point (or points) in the future. The server checks that the statements are executable (syntactically valid, name tables that exist, etc.) before enqueueing them, but they may still fail upon later execution (e.g., if a statement from another batch of statements is applied first and it conflicts in some way, or if there is some data-related problem like a NULL value in a column to which NOT NULL would be added). If a statement fails, all subsequent statements in the batch are automatically cancelled.

If an operation already exists with the given operation id, the operation will be resumed and the returned future will complete when the original operation finishes. See more information in com.google.cloud.spanner.spi.v1.GapicSpannerRpc#updateDatabaseDdl(String, Iterable, String)

Example to update the database DDL.


 String instanceId = my_instance_id;
 String databaseId = my_database_id;
 dbAdminClient.updateDatabaseDdl(instanceId,
     databaseId,
     Arrays.asList("ALTER TABLE Albums ADD COLUMN MarketingBudget INT64"),
     null).waitFor();

Parameters

Name	Description
instanceId	`String`
databaseId	`String`
statements	`Iterable<String>`
operationId	`String` Operation id assigned to this operation. If null, system will autogenerate one. This must be unique within a database abd must be a valid identifier a-zA-Z*.

Returns

Type	Description
OperationFuture<Void,UpdateDatabaseDdlMetadata>

Exceptions

Type	Description
SpannerException
