Expand description
A modification to one or more Cloud Spanner rows. Mutations can be applied to a Cloud Spanner database by sending them in a Commit call.
This type is not used in any activity, and only used as part of another schema.
Fields§
§insert: Option<Write>
Insert new rows in a table. If any of the rows already exist,
the write or transaction fails with error ALREADY_EXISTS
.
replace: Option<Write>
Like insert, except that if the row already exists, it is
deleted, and the column values provided are inserted
instead. Unlike insert_or_update, this means any values not
explicitly written become NULL
.
insert_or_update: Option<Write>
Like insert, except that if the row already exists, then its column values are overwritten with the ones provided. Any column values not explicitly written are preserved.
update: Option<Write>
Update existing rows in a table. If any of the rows does not
already exist, the transaction fails with error NOT_FOUND
.
delete: Option<Delete>
Delete rows from a table. Succeeds whether or not the named rows were present.
