What does the CreateOrUpdate Entity Action do when the Id Input Parameter is not null?

The CreateOrUpdate Entity Action is designed to facilitate the management of records in a database with ease. When the Id Input Parameter is provided and is not null, this action interprets that the user intends to update an existing record in the database rather than creating a new one.

In practice, if the Id corresponds to a valid record, the action retrieves that record and applies the changes specified in the other parameters to update it with the new values. This streamlined functionality allows developers to handle record modifications efficiently, encapsulating both creation and update processes within a single action but distinctly identifying when the update operation should occur.

While it is true that the action can also create a new record when the Id is null (indicating that no existing record can be found), its primary role when an Id is provided is to perform the update operation on the existing data linked to that Id. This understanding of the CreateOrUpdate action is essential for effective data manipulation in the OutSystems platform.

Understanding this is crucial for developers to ensure they utilize the functionality of the platform fully, promoting efficiency and reducing the likelihood of errors in record management tasks.
