Reference documentation and code samples for the Cloud Spanner V1 Client class UpdateDatabaseDdlRequest.
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.
Each batch of statements is assigned a name which can be used with the Operations API to monitor progress. See the operation_id field for more details.

getOperationId
If empty, the new update request is assigned an
automatically-generated operation ID. Otherwise, operation_id
is used to construct the name of the resulting
Operation.
Specifying an explicit operation ID simplifies determining
whether the statements were executed in the event that the
UpdateDatabaseDdl call is replayed,
or the return value is otherwise lost: the database and
operation_id
fields can be combined to form the
name of the resulting
longrunning.Operation: <database>/operations/<operation_id>
.
operation_id
should be unique within the database, and must be
a valid identifier: [a-z][a-z0-9_]*
. Note that
automatically-generated operation IDs always begin with an
underscore. If the named operation already exists,
UpdateDatabaseDdl returns
ALREADY_EXISTS
.
Generated from protobuf field string operation_id = 3;
