Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ insert	Google\Cloud\Spanner\V1\Mutation\Write Insert new rows in a table. If any of the rows already exist, the write or transaction fails with error ALREADY_EXISTS.
↳ update	Google\Cloud\Spanner\V1\Mutation\Write Update existing rows in a table. If any of the rows does not already exist, the transaction fails with error NOT_FOUND.
↳ insert_or_update	Google\Cloud\Spanner\V1\Mutation\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. When using insert_or_update, just as when using insert, all NOT NULL columns in the table must be given a value. This holds true even when the row already exists and will therefore actually be updated.
↳ replace	Google\Cloud\Spanner\V1\Mutation\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. In an interleaved table, if you create the child table with the ON DELETE CASCADE annotation, then replacing a parent row also deletes the child rows. Otherwise, you must delete the child rows before you replace the parent row.
↳ delete	Google\Cloud\Spanner\V1\Mutation\Delete Delete rows from a table. Succeeds whether or not the named rows were present.
