＆＃34;（。＆＃34;和＆＃34;。）＆＃34;是什么意思？在PL / SQL？

Question

我找到了这个PL / SQL代码，但我在Oracle文档中找不到有效的代码：

CREATE OR REPLACE PROCEDURE hard_priv AS
BEGIN
    HTP.htmlOpen;
    HTP.headOpen;
    HTP.title (.Account Information.);
    HTP.headClose;
    HTP.bodyOpen;
    HTP.br;
    HTP.print('User ID: ' ||
               OWA_SEC.get_user_id || '');
    HTP.print('User Password: ' ||
               OWA_SEC.get_password || '');
    HTP.br;
    HTP.bodyClose;
    HTP.htmlClose;
END hard_priv;
END uu_hr_pkg;

Answer 1

“(.”和“.)”不是PLSQL语法。

所以无法编译。

这很简单：

begin
  dbms_output.put_line('this is the right syntax');
  dbms_output.put_line(.this_dont_work.);
end;
/

出现如下编译错误：

SQL> @a
dbms_output.put_line(.this_dont_work.);
                     *
ERROR at line 3:
ORA-06550: line 3, column 26:
PLS-00103: Encountered the symbol "." when expecting one of the following:
( ) - + case mod new not null <an identifier>
<a double-quoted delimited-identifier> <a bind variable> table continue avg count current exists max min prior sql
stddev sum variance execute multiset the both leading
trailing forall merge year month day hour minute second
timezone_hour timezone_minute timezone_region timezone_abbr
time timestamp interval date

     

在现实世界中，您必须将其替换为';你的东西应该是：

CREATE OR REPLACE PROCEDURE hard_priv AS
BEGIN
  HTP.htmlOpen;
  HTP.headOpen;
  HTP.title ('Account Information');
  HTP.headClose;
....
