Name Description
table str
Required. The table whose rows will be written.
columns MutableSequence[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 MutableSequence[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].
