この用語は、コマンドの実行中にモデルが更新される回数を指します。コマンドを安全に実行するために、何らかのスコープのトランザクションが必要かどうかを判断します。
数え方は以下のとおり:
Count | Description |
---|---|
| This command performs no updates |
| Indicates that only one model is updated by this command (and its subcommands). Also, the success or failure of that update corresponds to the success or failure of the command. It should not be possible for the update to succeed while the command fails. Execution is not considered transactionally unsafe |
| Any number greater than 1 indicates that execution is transactionally unsafe, and an XA transaction will be required |
