59. In your database, the current status of a PL/SQL procedure has become INVALID. Which action

would fix the problem and make the PL/SQL procedure usable?

A.Recompile the PL/SQL procedure.

B.Modify the procedure to run with a definer's right.

C.Modify the procedure to run with an invoker's right.

D.Grant the EXECUTE privilege on the PL/SQL procedure to PUBLIC.

Answer: A

proc失效，重新编译就可以了。

在调用该失效的proc时，也会自动编译。
