PROCEDURE GET_NEWS 出現錯誤:
LINE/COL ERROR

4/1 PLS-00428: 在此 SELECT 語句中缺少 INTO 子句
SQL> create or replace procedure get_news

3 aa number;
4 begin
5 select count(*) into aa from cf_news;
6 end;
7 /
過程已創建。
SQL> create or replace procedure get_news

5 select count(*) into aa from cf_news;
6 dbms_outpub.put_line('aa='aa);
