PLS-00103: 为序号 oracle 创建触发器

Question

我有这个脚本。基本上在table.

中增加一个主键

CREATE OR REPLACE FORCE TRIGGER SISD_OWNER.TRG_SN_MAP_UNIT_RELA_SEQ
BEFORE INSERT ON SISD_OWNER.ADV_SN_MAP_UNIT_RELA
FOR EACH ROW
DECLARE
  m_next_seq_num NUMBER := 0;
BEGIN
  IF :new.SEQUENCE_NUMBER is null THEN
    select
        ADV_SN_MAP_UNIT_RELA_SEQ.NextVal
    into m_next_seq_num
    from dual;
    :new.SEQUENCE_NUMBER := m_next_seq_num;
  END IF;
END;

当在 sqlplus (cmd) 上运行时，我得到：

LINE/COL ERROR
-------- -----------------------------------------------------------------
2/28     PLS-00103: Encountered the symbol "end-of-file" when expecting
     one of the following:
     * & = - + ; < / > at in is mod remainder not rem
     <an exponent (**)> <> or != or ~= >= <= <> and or like like2
     like4 likec between || multiset member submultiset

不确定错误到底是什么？

Answer 1

删除关键字 FORCE。触发器不存在该选项。（虽然我希望这样做 - 有时在 table 或序列存在之前创建触发器会很好。）

Answer 2

如果您的数据库版本为 11g 或更高。然后使用可简化代码并提高工作效率的新功能。

CREATE OR REPLACE TRIGGER SISD_OWNER.TRG_SN_MAP_UNIT_RELA_SEQ
BEFORE INSERT ON SISD_OWNER.ADV_SN_MAP_UNIT_RELA
FOR EACH ROW
DECLARE

BEGIN
  IF :new.SEQUENCE_NUMBER is null THEN
    :new.SEQUENCE_NUMBER := ADV_SN_MAP_UNIT_RELA_SEQ.NextVal;
  END IF;
END;
