replace][google.spanner.v1.Mutation.replace] operations.
Attributes
| Name | Description |
| table |
str
Required. The table whose rows will be written. |
| columns |
Sequence[str]
The names of the columns in `table][google.spanner.v1.Mutation.Write.table]` to be written. The list of columns must contain enough columns to allow Cloud Spanner to derive values for all primary key columns in the row(s) to be modified. |
| values |
Sequence[google.protobuf.struct_pb2.ListValue]
The values to be written. ``values`` can contain more than one list of values. If it does, then multiple rows are written, one for each entry in ``values``. Each list in ``values`` must have exactly as many entries as there are entries in `columns][google.spanner.v1.Mutation.Write.columns]` above. Sending multiple lists is equivalent to sending multiple ``Mutation``\ s, each containing one ``values`` entry and repeating `table][google.spanner.v1.Mutation.Write.table]` and `columns][google.spanner.v1.Mutation.Write.columns]`. Individual values in each list are encoded as described `here][google.spanner.v1.TypeCode]`. |
