感谢到目前为止的家伙，

我觉得我在你的帮助下越走越远！

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，在按照向导要求设置主键列时，我一旦设置了主键列，就无法向其中添加 ROWS。

为了了解我的意思是这个例子：

无法添加日程编号。

这是该表的 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，当我尝试将行添加到表中时，出现错误：

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)
