在 Oracle SQL 开发人员中使用 for 循环

Question

下面的代码给了我这个错误

ORA-00933: SQL 命令未正确结束 00933. 00000 - “SQL 命令未正确结束” *原因：
*行动： 行错误：26 列：1

for i in (7,14,21,28,35) 
loop
  Select CODE_ACCOUNTING_METHOD,
         trunc(sysdate-i, 'iw')           as week_report,
         sum(ELI_12MOB)                   as eligible_client,
         sum(client)                      as total_client,
         (sum(ELI_12MOB)/sum(client))*100 as eligible_rate
   from  pm_eli_base
   where week_start = trunc(sysdate-(360+i), 'iw')
     and code_accounting_method != 'CL'
   group by CODE_ACCOUNTING_METHOD, trunc(sysdate-i, 'iw')
   union all
   select 'Total', 
           trunc(sysdate-i, 'iw') as week_report,
           sum(ELI_12MOB)         as eligible_client,
           sum(client)            as total_client,
           (sum(ELI_12MOB)/sum(client))*100
     from pm_eli_base
    where week_start = trunc(sysdate-(360+i), 'iw')
      and code_accounting_method != 'CL'
    group by 'Total', trunc(sysdate-i, 'iw')
end loop;

请帮我解决这个问题

This is the result I want to achieve

Answer 1

由于您使用的是 SQLDeveloper，因此您可以在游标中声明您的查询，并在 i 的选择值上调用您的游标

DECLARE 

CURSOR code_accounting_method(i number)
is
Select CODE_ACCOUNTING_METHOD,
         trunc(sysdate-i, 'iw')           as week_report,
         sum(ELI_12MOB)                   as eligible_client,
         sum(client)                      as total_client,
         (sum(ELI_12MOB)/sum(client))*100 as eligible_rate
   from  pm_eli_base
   where week_start = trunc(sysdate-(360+i), 'iw')
     and code_accounting_method != 'CL'
   group by CODE_ACCOUNTING_METHOD, trunc(sysdate-i, 'iw')
   union all
   select 'Total', 
           trunc(sysdate-i, 'iw') as week_report,
           sum(ELI_12MOB)         as eligible_client,
           sum(client)            as total_client,
           (sum(ELI_12MOB)/sum(client))*100
     from pm_eli_base
    where week_start = trunc(sysdate-(360+i), 'iw')
      and code_accounting_method != 'CL'
    group by 'Total', trunc(sysdate-i, 'iw');

 cam_record  CODE_ACCOUNTING_METHOD%rowtype;

BEGIN

        for i in 1 .. 35 loop
          if i in (7,14,21,28,35) then
                open code_accounting_method(i);
                fetch code_accounting_method into  cam_record;
                close code_accounting_method;
               --Now report the fields that are in cam_record;
               -- such as 
              dbms_output.put_line(cam_record.week_report);

          end if;
        end loop;
END;      

Answer 2

你不能这样做：

for i in (7,14,21,28,35)

做：

SQL> 
declare
   type nt_type is table of number;
   nt nt_type := nt_type (7,14,21,28,35);
begin
for i in 1..nt.count loop
   dbms_output.put_line(nt(i));
end loop;
end;
/

7
14
21
28
35

PL/SQL procedure successfully completed.

Answer 3

首先你在查询结束时错过了;。

其次，您想通过选择查询来实现什么？使用INTO 为某个变量赋值。

更新： 除了@btpys 建议的内容之外，您还可以使用以下技术。

FOR J IN 1..5 LOOP
I := J*7;
...
...
END LOOP;

干杯！！

Answer 4

我认为for 循环是错误的工具。 您应该创建一个视图，并使用 union all 并手动复制和粘贴并将 i 替换为值 7,14,21,28,35。这样您就可以看到带有 union all 5x2 次 = 10 条选择语句的视图。
