問題文
A stored procedure compiles with a message that does not prevent the compilation from succeeding, and the developer wants to know where such messages are kept. Which description of compile time warnings is correct?
選択肢
- They report conditions that stop the compilation of the unit, and they are read from the record of the instance that the administrator keeps for the whole database rather than for one unit.
- They report conditions that appear while the unit runs rather than while it is compiled, and they are raised as exceptions that the calling block is able to handle in its own handlers.
- They report conditions that are not serious enough to stop the compilation, and they are read from the data dictionary view that holds the messages of a program unit.
- They report conditions that the developer marked in the source with a pragma, so a unit without such a pragma produces no warnings no matter what its source text contains.
