Which command type cannot be used with the Program Command shape?

The Program Command shape in Boomi is designed to execute commands or scripts in order to perform operations on data, typically aimed at modifying or interacting with that data in some fashion. The key to understanding the correct answer lies in recognizing the purpose and function of the various command types associated with this shape.

INSERT, UPDATE, and DELETE commands are all data manipulation commands that are intended to change the state of data within a database. These commands allow the user to add new records, change existing records, and remove records, respectively. Thus, they align well with the capabilities of the Program Command shape, which can be used to perform these types of operations directly.

On the other hand, the SELECT command is primarily a query operation used to retrieve or read data from a database without modifying it. Since the Program Command shape is typically associated with executing commands that lead to data modification, using it with a SELECT command would be inappropriate. This is because the shape is not intended for fetching data but for executing commands that alter it.

Therefore, the SELECT command cannot be executed using the Program Command shape, making it the correct choice for this question.
