sql - Ora-04072 : INVALID TRIGGER TYPE

Question

我正在尝试在 Oracle 11g 上执行以下 SQL 语句。我对 Oracle 没有经验，我不确定为什么会失败。这个查询是由我们的开发人员提供给我的。

我试图通过 OEM 中的 SQL 工作表执行此操作。

CREATE OR REPLACE TRIGGER TBL_ADMINCOMMAND_TRG BEFORE 
INSERT OR UPDATE ON tbl_AdminCommands FOR EACH ROW 
BEGIN 
IF inserting
AND :new.ADMINCOMMANDID IS NULL THEN
SELECT TBL_ADMINCOMMANDS_SEQ.nextval INTO :new.ADMINCOMMANDID FROM DUAL;
END IF;
END;
ALTER TRIGGER TBL_ADMINCOMMAND_TRG ENABLE;

Answer 1

您显示的代码对我有效，但仅作为两个单独的命令:

1)

CREATE OR REPLACE TRIGGER TBL_ADMINCOMMAND_TRG BEFORE 
INSERT OR UPDATE ON tbl_AdminCommands FOR EACH ROW 
BEGIN 
IF inserting
AND :new.ADMINCOMMANDID IS NULL THEN
SELECT TBL_ADMINCOMMANDS_SEQ.nextval INTO :new.ADMINCOMMANDID FROM DUAL;
END IF;
END;

2)

ALTER TRIGGER TBL_ADMINCOMMAND_TRG ENABLE;

试着一次做一个。

顺便说一句，这一行:

SELECT TBL_ADMINCOMMANDS_SEQ.nextval INTO :new.ADMINCOMMANDID FROM DUAL;

在11G可以简化成这样:

:new.ADMINCOMMANDID := TBL_ADMINCOMMANDS_SEQ.nextval;

其实整个触发器可以简化为:

CREATE OR REPLACE TRIGGER TBL_ADMINCOMMAND_TRG
BEFORE INSERT ON tbl_AdminCommands 
FOR EACH ROW 
WHEN (NEW.ADMINCOMMANDID IS NULL)
BEGIN 
    :new.ADMINCOMMANDID := TBL_ADMINCOMMANDS_SEQ.nextval;
END;
