mru内部例程出错：ORA-20001 / Timestamp / NULL主键

Question

到目前为止，谢谢你们，

我觉得我首先得到的是你的帮助！

但是，当我使用oracle提供的表单向导时，我现在遇到了另一个问题。

我遇到的问题是在关注向导时要求设置主键列，但是一旦我有了，我就无法添加ROWS。

要了解我的意思，这里是一个例子：

无法添加计划编号。

以下是表格的SQL：

CREATE TABLE  "MACHINE_SCHEDULE" 
   (    "SCHEDULE_NUMBER" VARCHAR2(40 CHAR), 
    "MACHINE_NO" VARCHAR2(10 CHAR), 
    "MACHINE_USE_DATE" DATE, 
    "START_TIME" TIMESTAMP (3) WITH TIME ZONE, 
    "END_TIME" TIMESTAMP (3) WITH TIME ZONE, 
    "PROCESS" VARCHAR2(164 CHAR), 
    "BATCH_NO" VARCHAR2(10 CHAR), 
    "MATERIAL_BAR_NO" NUMBER(8,0), 
    "TECHNICIAN_STAFF_NO" VARCHAR2(15 CHAR), 
     CONSTRAINT "MACHINE_SCHEDULE_PK" PRIMARY KEY ("SCHEDULE_NUMBER") ENABLE
   )
/
ALTER TABLE  "MACHINE_SCHEDULE" ADD CONSTRAINT "MACHINE_SCHEDULE_CON" FOREIGN KEY ("TECHNICIAN_STAFF_NO")
      REFERENCES  "MODULE_TECHNICIAN" ("TECHNICIAN_STAFF_NO") ENABLE
/
ALTER TABLE  "MACHINE_SCHEDULE" ADD CONSTRAINT "MACHINE_SCHEDULE_FK" FOREIGN KEY ("BATCH_NO")
      REFERENCES  "BATCH" ("BATCH_NO") ENABLE
/
ALTER TABLE  "MACHINE_SCHEDULE" ADD CONSTRAINT "MACHINE_SCHEDULE_FK2" FOREIGN KEY ("MATERIAL_BAR_NO")
      REFERENCES  "MATERIAL_BAR" ("MATERIAL_BAR_NO") ENABLE
/

CREATE OR REPLACE TRIGGER  "BI_MACHINE_SCHEDULE" 
  before insert on "MACHINE_SCHEDULE"               
  for each row  
begin   
  if :NEW."SCHEDULE_INSTANT_NUMBER" is null then 
    select "MACHINE_SCHEDULE_SEQ".nextval into :NEW."SCHEDULE_INSTANT_NUMBER" from dual; 
  end if; 
end; 

/
ALTER TRIGGER  "BI_MACHINE_SCHEDULE" DISABLE
/

但是，当我尝试在表中添加行时，我收到错误：

Error in mru internal routine: ORA-20001: Error in MRU: row= 1, 
ORA-01438: value larger than specified precision allowed for this column, 
insert into "GROUP7_1"."MACHINE_SCHEDULE" ( "SCHEDULE_NUMBER", "MACHINE_NO", "MACHINE_USE_DATE", "START_TIME", "END_TIME", "PROCESS", "BATCH_NO", "MATERIAL_BAR_NO", "TECHNICIAN_STAFF_NO") 
values ( :b1, :b2, :b3, :b4, :b5, :b6, :b7, :b8, :b9)
