In Oracle, you can declare a procedure or a function without its body, and write the implementation later. The inspection will report names of such procedures or functions that are left without implementation.
Example (Oracle):
DECLARE PROCEDURE foo(a int, b varchar2);
BEGIN
NULL;
END;
The foo procedure is declared but is missing implementation. We can add the implementation to get rid of the error.
DECLARE PROCEDURE foo(a int, b varchar2);
PROCEDURE foo(a int, b varchar2) IS
BEGIN
NULL;
END;
BEGIN
NULL;
END;
