Question

在命令的第1行开始出错：

DECLARE
   x NUMBER := 0;
   counter NUMBER := 0;
BEGIN
   FOR i IN 1..4 LOOP
      x := x + 1000;
      counter := counter + 1;
      INSERT INTO temp VALUES (x, counter, 'in OUTER loop');
      END;
   END LOOP;
   COMMIT;
END;

错误报告：

ORA-06550: line 11, column 10:
PLS-00103: Encountered the symbol ";" when expecting one of the following:

loop
06550. 00000 -  "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
*Action:

Answer 1

此插入模式不需要PL / SQL。以下适用于纯SQL：

create table temp(x number, counter number, text varchar2(20));

insert into temp
select (rownum-1)*1000, rownum-1, 'in OUTER loop'
from dual
connect by level <=4;

Answer 2

第11行的第一个END;不应该在那里：

DECLARE
   x NUMBER := 0;
   counter NUMBER := 0;
BEGIN
   FOR i IN 1..4 LOOP
      x := x + 1000;
      counter := counter + 1;
      INSERT INTO temp VALUES (x, counter, 'in OUTER loop');
   END LOOP;
   COMMIT;
END;

如果您在INSERT（例如）周围有一个子块，您只需要它，例如用于特定的异常处理。

通常，在INSERT：

中指定列名称也会更好

      INSERT INTO temp(col1, col2, col3) VALUES (x, counter, 'in OUTER loop');

for循环中的语法错误
