PLS-00103：在期望以下之一时遇到符号 "END"：:= 。 ( % ; 符号“;”被替换为 "END" 以继续

Question

您好，我刚开始学习 PLSQL，目前遇到此错误，但我不确定是什么导致了这个问题。

对于我的作业，我应该创建一个 PLSQL 过程，该过程接受用户输入 x 到 return 国家及其各自地区的列表。

R_NAME	N_NAME	COUNT(S_NATIONKEY)
ASIA	INDONESIA	131
ASIA	CHINA	145
MIDDLE EAST	SAUDI ARABIA	132
EUROPE	GERMANY	132

SQL> DECLARE
  2          userInput number;
  3  
  4  PROCEDURE numberOfSupplier(x IN number) IS
  5          -- Declaring variables to be used
  6          r_name region.r_name%type;
  7          n_name nation.n_name%type;
  8  
  9  
 10  BEGIN
 11          -- Print header
 12          dbms_output.put_line(lpad('R_name',25) || lpad('N_Name',25) || lpad('Count(s_nationkey)',25));
 13          dbms_output.put_line('-------------------' || '-------------------' || '-------------------');
 14  
 15          -- Create an implicit cursor to bring in the data
 16  
 17          for Qrow in (
 18              select r_name, n_name, count(s_nationkey) AS cnt
 19                  from region , nation, supplier
 20                  where r_regionkey = n_regionkey
 21                  and n_nationkey = s_nationkey
 22                  group by r_name, n_name
 23                  having count(s_nationkey) > x
 24                  order by r_name)
 25  
 26          -- Loop through query to print to terminal
 27  
 28          loop
 29              dbms_output.put_line(Qrow.r_name || Qrow.n_name || Qrow.cnt);
 30          end loop;
 31  
 32  
 33  END;
 34  
 35  -- Executes Procedure
 36  
 37  BEGIN
 38          userInput := (&MinNumberofsupplier);
 39          numberOfSupplier(userInput);
 40  END;
 41  
 42  /

这是终端中的错误信息

SQL> show errors;
Errors for PROCEDURE NUMBEROFSUPPLIER:

LINE/COL ERROR
-------- -----------------------------------------------------------------
31/2     PLS-00103: Encountered the symbol "END" when expecting one of the
     following:

     The symbol ";" was substituted for "END" to continue.

我建议您创建一个存储过程（而不是匿名 PL/SQL 块），然后从您想要的任何地方调用该过程。

我删除了不必要的局部变量声明（因为您从未使用过它们）。

SQL> create or replace procedure numberofsupplier(x in number) is
  2  begin
  3    -- Print header
  4    dbms_output.put_line(lpad('R_name',25) || lpad('N_Name',25) || lpad('Count(s_nationkey)',25));
  5    dbms_output.put_line('-------------------' || '-------------------' || '-------------------');
  6
  7    -- Create an implicit cursor to bring in the data
  8    for qrow in (
  9                 select r_name, n_name, count(s_nationkey) as cnt
 10                     from region , nation, supplier
 11                     where r_regionkey = n_regionkey
 12                     and n_nationkey = s_nationkey
 13                     group by r_name, n_name
 14                     having count(s_nationkey) > x
 15                     order by r_name)
 16    -- Loop through query to print to terminal
 17    loop
 18      dbms_output.put_line(qrow.r_name || qrow.n_name || qrow.cnt);
 19    end loop;
 20  end;
 21  /

Procedure created.

我们称它为：

SQL> -- Executes Procedure
SQL> set serveroutput on
SQL> begin
  2    numberofsupplier(&userinput);
  3  end;
  4  /
Enter value for userinput: 1
R_name                   N_Name       Count(s_nationkey)
---------------------------------------------------------

PL/SQL procedure successfully completed.

没有输出，因为我的表是空的，但是 - 您可能应该看到一些东西（使用您的表）。
