Oracle-Sqldeveloper函数：“END my_function;”中的编译错误声明

Question

所以我调试SQL函数编译错误：

错误（16,1）：PLS-00103：出现符号“/”

..这是在最后出现功能：

create or replace 
function total_weekdays(fromdate in date, todate in date) 
    return number 
    as totaldays number := 0; 
    dates number := 0; 
BEGIN 
    select to_number(count(dates)) into totaldays from 
    (select to_char(fromdate + level -1, 'dd/mm/YYYY DY') as dates 
    from dual connect by level <= todate - fromdate +1 
    minus 
    select to_char(ho_date, 'dd/mm/YYYY DY') as dates 
    from FS.fs_holiday 
    ) where not regexp_like(dates,'SUN|SAT'); 
return totaldays; 
END; 
/

Prompt *** RPT_PACK_GEN_INV_MOVEMENT Package *** 
CREATE OR REPLACE PACKAGE REPORTS_CLIENT."RPT_PACK_GEN_INV_MOVEMENT" AS 

    Procedure GEN_INV_MOVEMENT(pv_RunDate_i DATE default null); 
    Procedure RE_GEN_INV_MOVEMENT(pv_RunDate_i DATE default null); 
    Procedure GEN_INV_MOVEMENT_SUMMARY(pv_RunDate_i DATE default null); 
    Procedure GEN_Opening(pv_RunDate_i DATE); 

end RPT_PACK_GEN_INV_MOVEMENT;

你已经证明什么工作表（不用于演示的FS.模式前缀）编译OK：

create table fs_holiday(ho_date date); 

create or replace 
function total_weekdays(fromdate in date, todate in date) 
    return number 
    as totaldays number := 0; 
    dates number := 0; 
BEGIN 
    select to_number(count(dates)) into totaldays from 
    (select to_char(fromdate + level -1, 'dd/mm/YYYY DY') as dates 
    from dual connect by level <= todate - fromdate +1 
minus 
select to_char(ho_date, 'dd/mm/YYYY DY') as dates 
from fs_holiday 
) where not regexp_like(dates,'SUN|SAT'); 
return totaldays; 
END; 
/

Function TOTAL_WEEKDAYS compiled 

如果您在对象查看器中打开该函数，然后单击SQL选项卡，则会显示没有结尾的斜杠。

添加斜线回，然后编译它然后给你看到的错误，

Error(15,1): PLS-00103: Encountered the symbol "/" The symbol "/" was ignored. 

在对象浏览器环境下，你不应该有斜线。在工作表中，为in SQL*Plus，SQL开发人员：

... treats PL/SQL subprograms in the same manner as SQL commands, except that a semicolon (;) or a blank line does not terminate and execute a block. Terminate PL/SQL subprograms by entering a period (.) by itself on a new line. You can also terminate and execute a PL/SQL subprogram by entering a slash (/) by itself on a new line.

所以在工作表中的斜杠是必要的分隔（命名）块的结尾，并确定create声明的全部。

在对象浏览器，你只看到该对象的代码，所以没有必要有斜杠分隔符，一切都在SQL窗口被视为对象源代码的一部分。

同样，如果你在user_source数据字典视图看，有没有存放斜杠线。

select line, text from user_source where name = 'TOTAL_WEEKDAYS' order by line; 

     LINE TEXT 
---------- -------------------------------------------------------------------------------- 
     1 function total_weekdays(fromdate in date, todate in date) 
     2 return number 
     3 as totaldays number := 0; 
     4 dates number := 0; 
     5 BEGIN 
     6 select to_number(count(dates)) into totaldays from 
     7 (select to_char(fromdate + level -1, 'dd/mm/YYYY DY') as dates 
     8 from dual connect by level <= todate - fromdate +1 
     9 minus 
     10 select to_char(ho_date, 'dd/mm/YYYY DY') as dates 
     11 from fs_holiday 
     12 ) where not regexp_like(dates,'SUN|SAT'); 
     13 return totaldays; 
     14 END; 

14 rows selected. 

它是客户端语句处理的一部分，而不是函数的一部分。

如果你是在对象浏览器，那么你不能创建在同一个SQL窗口中的第二个对象。这是您正在查看的对象的源代码。

如果要在脚本中一次创建多个对象，请使用工作表（右键单击连接并选择“打开SQL Worksheet”），将所有代码放入，然后作为脚本运行（F5） 。如果您想使用对象视图，然后展开连接，请右键单击“包”选项，然后选择“新建包”。
