oracle 顶点 sql 的简单触发/程序问题

Question

我试图在 oracle 顶点 sql 中运行此审计跟踪触发器，但我一直收到同样的错误，我不知道我做错了什么。 我还需要对数据库中的每个表执行相同的触发器...有没有办法我可以通过一个过程执行相同的操作以便只执行一次？

create or replace TRIGGER AUDIT_TRAIL_USERS_TRIG
  -- starts on every update, insert or delete command
  AFTER INSERT OR DELETE OR UPDATE ON USERS
  FOR EACH ROW
DECLARE
  -- variable which declares if update, delete or insert process
  v_trg_action varchar2(10);
BEGIN
  IF updating  THEN
    -- when update
    v_trg_action := 'UPDATE';
  ELSIF deleting  THEN
    -- when delete
    v_trg_action := 'DELETE';
  ELSIF inserting  THEN
    -- when insert
    v_trg_action := 'INSERT';
  ELSE
    -- if something else
  END IF;
  IF v_trg_action IN ('DELETE','UPDATE','INSERT') THEN
      -- if v_trg_action is DELETE, UPDATE OR INSERT then insert old table values
   INSERT INTO AUDIT_TRAIL
  ( AUDIT_USER,  AUDIT_DATE,  AUDIT_ACTION)
   VALUES
  (UPPER(v('APP_USER')), SYSDATE, v_trg_action);
  ELSE
  END IF;
  -- about the insert command on the audit table
  -- for current apex user: v('APP_USER')
  -- for date: SYSDATE
  -- for sql command: v_trg_action   
END AUDIT_TRAIL_USERS_TRIG;

我得到的错误（我确定我比它对我说的更多）如下：

编译失败，第 16 行 (03:29:53) 与编译错误相关的行号与第一个 BEGIN 语句相关。 这只会影响数据库触发器的编译。

PLS-00103: Encountered the symbol "END" when expecting one of the following: ( begin case declare exit for goto if loop mod null pragma raise return select update while with << continue close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe purge json_exists json_value json_query json_object json_array Compilation failed, line 25 (03:29:53) 与编译错误相关的行号是相对于第一个 BEGIN 语句的，这只影响数据库触发器的编译。

PLS-00103: Encountered the symbol "END" when expecting one of the following: ( begin case declare exit for goto if loop mod null pragma raise return select update while with << continue close current delete fetch lock insert open rollback savepoint set sql execute提交 forall 合并 pipe 清除 json_exists json_value json_query json_object json_array

IF..ELSE 块不能为空。 如果您不需要它们将其删除，我添加了一个虚拟NULL调用以编译代码。根据需要添加适当的逻辑，否则删除该块。

create or replace TRIGGER AUDIT_TRAIL_USERS_TRIG
  -- starts on every update, insert or delete command
  AFTER INSERT OR DELETE OR UPDATE ON USERS
  FOR EACH ROW
DECLARE
  -- variable which declares if update, delete or insert process
  v_trg_action varchar2(10);
BEGIN
  IF updating  THEN
    -- when update
    v_trg_action := 'UPDATE';
  ELSIF deleting  THEN
    -- when delete
    v_trg_action := 'DELETE';
  ELSIF inserting  THEN
    -- when insert
    v_trg_action := 'INSERT';
  ELSE
    -- if something else
    NULL;
  END IF;
  IF v_trg_action IN ('DELETE','UPDATE','INSERT') THEN
      -- if v_trg_action is DELETE, UPDATE OR INSERT then insert old table values
   INSERT INTO AUDIT_TRAIL
  ( AUDIT_USER,  AUDIT_DATE,  AUDIT_ACTION)
   VALUES
  (UPPER(v('APP_USER')), SYSDATE, v_trg_action);

  null;
  ELSE
   NULL;
  END IF;
  -- about the insert command on the audit table
  -- for current apex user: v('APP_USER')
  -- for date: SYSDATE
  -- for sql command: v_trg_action   
END AUDIT_TRAIL_USERS_TRIG;

使用此代码，它将像您的一样工作

create or replace TRIGGER AUDIT_TRAIL_USERS_TRIG
  AFTER INSERT OR DELETE OR UPDATE ON USERS
  FOR EACH ROW
DECLARE
BEGIN
    IF inserting or updating or deleting  THEN
        INSERT INTO AUDIT_TRAIL
            (AUDIT_USER,  AUDIT_DATE,  AUDIT_ACTION)
        VALUES
            (UPPER(v('APP_USER')), SYSDATE, v_trg_action);
    END IF;  
END AUDIT_TRAIL_USERS_TRIG;
