Oracle 无效的插入SQL Vs PL/SQL & 12c Vs 11g

嗨，团队，

最近，我们在生产系统中遇到了一个错误 (这是我们的编码错误!)，但是在调查相同的内容时，我注意到了这一点。

执行以下操作:
1) 表创建:

create table dept( 
dept_no varchar2(15), 
dept_name varchar2(30), 
loc varchar2(30));

2) SQL插入:

insert into dept values ('10','president's','washington d.c');

3) PL/SQL插入:

DECLARE 
l_sql VARCHAR2(32767); 
BEGIN 
  l_sql := 'INSERT INTO DEPT VALUES ('; 
  L_sql := l_sql || '''50'''; 
  l_sql := l_sql ||', ''president''s'', ''washington d.c'')'; 
  dbms_output.put_line(l_sql); 
  EXECUTE IMMEDIATE l_sql; 
END;

当我在11g和12c中运行上述SQL和PL/SQL插入时收到的错误代码如下:

Version      - 12c
SQL Error    - ORA-00917: missing comma
PL/SQL Error - ORA-00917: missing comma ORA-06512: at line 8
               ORA-06512: at "SYS.DBMS_SQL", line 1721

Version      - 11g
SQL Error    - ORA-01756: quoted string not properly terminated
PL/SQL Error - ORA-00917: missing comma ORA-06512: at line 8

我们得到的错误在12c版本的SQL和PL/SQL中是统一的，但我个人认为11g SQL错误更有意义，有助于确定错误的根本原因。
请告诉我你的观点。

我同意如果PL/SQL消息与SQL消息匹配会很好，但是很抱歉，我无法重现您提到的11g和12c之间的差异。
