Oracle中没有找到数据错误

我正在尝试将数据插入到oracle数据库(版本11g xe)。但是当我尝试使用toad执行该过程时,我收到错误为'ORA-01403:未找到数据'。 这是我的代码

CREATE OR REPLACE PROCEDURE ACTSINFO.sp_Insert_WorkDetails 
(p_workname IN varchar ,
p_workaddress IN varchar)
IS
BEGIN   
   insert into workdetails (workname,workaddress) values (p_workname,p_workaddress);
END sp_Insert_WorkDetails;

我尝试使用以下statememt

执行该过程
EXEC sp_Insert_WorkDetails('test','test');

此外,我已经为表workdetails中workdetailsid的自动增量定义了一个触发器和序列

序列如下

 ALTER SEQUENCE ACTSINFO.WORKDETAILS_WORKID_SEQ
 INCREMENT BY 1
 MINVALUE 0
 MAXVALUE 9999999999999999999999999999
 NOCACHE
 NOCYCLE
 NOORDER

触发如下

DROP TRIGGER ACTSINFO.WORKDETAILS_INSERT;
CREATE OR REPLACE TRIGGER ACTSINFO.WORKDETAILS_INSERT
BEFORE INSERT
ON ACTSINFO.WORKDETAILS
REFERENCING NEW AS New OLD AS Old
FOR EACH ROW
BEGIN
  SELECT WORKDETAILS_WORKID_SEQ.NEXTVAL INTO :NEW.WORKID FROM WORKDETAILS;
END;

我是oracle的新手。请帮助我......

答案 0 :(得分:7)

您的触发器是问题所在:

SELECT WORKDETAILS_WORKID_SEQ.NEXTVAL INTO :NEW.WORKID FROM WORKDETAILS;

如果workdetails中没有行,则select将不返回任何内容。更糟糕的是,如果你的workdetails表有多行,那么这也会失败。

你真的想要以下内容:

SELECT WORKDETAILS_WORKID_SEQ.NEXTVAL INTO :NEW.WORKID FROM dual;

或 - 如果您使用11g - 那么您可以使用:

:NEW.WORKID := WORKDETAILS_WORKID_SEQ.NEXTVAL;
