Answer 1

没有分区的正确语法：

SELECT ......
       ROW_NUMBER() OVER(ORDER BY 1) 
FROM ...

如果您希望按部门或W / E划分，则：

SELECT ......
       ROW_NUMBER() OVER(PARTITION BY YourColumn ORDER BY TheOrderColumn) 
FROM ...

Answer 2

双重声明不正确。 Dual是一个表，您需要指定如何计算row_number。你可能需要：

select COMPANYCODE, DIVISIONCODE, CATEGORYICSTABLECODE,
         CATEGORYCODE, CATEGORYTYPE,CODE,
         FACTORYCODE, DEPARTMENTDEPARTMENTCODE, SECTIONSECTIONICSTABLECODE,
         SECTIONSECTIONCODE, MATYPEMACHINETYPEICSTABLECODE, MACHINETYPEMACHINETYPECODE,
         MACHINENOMACHINENOICSTABLECODE, MACHINENOMACHINENOCODE, GRADEICSTABLECODE,
         GRADECODE, CADREICSTABLECODE, CADRECODE,
         DESGDESIGNATIONICSTABLECODE, DESGDESIGNATIONCODE, EMPROLECODE,
         SUBCTGSUBCATEGORYICSTABLECODE, SUBCATEGORYSUBCATEGORYCODE, FROMDATE,
         TODATE, CONFIRMATIONDATE, RESIGNDATE,
         JOININGDATE, p_creationtimestamp, ROW_NUMBER() OVER (order by 1),
         ' ', ' ', sysdate,
         ' ', 0, 0,
         0
  from  employee;

如果您只想要没有任何指定分区或订单的行号，则可以将ROW_NUMBER() OVER (order by 1)替换为rownum。或者，如果您想要某个指定的订单，请按照表示订单的列名替换1。

此外，您需要注意，当您第二次执行插入时，SERIAL将从1重新开始。如果您需要唯一的号码，请

create sequence serial_seq start with 1 increment by 1;

并使用：

select COMPANYCODE, DIVISIONCODE, CATEGORYICSTABLECODE,
         CATEGORYCODE, CATEGORYTYPE,CODE,
         FACTORYCODE, DEPARTMENTDEPARTMENTCODE, SECTIONSECTIONICSTABLECODE,
         SECTIONSECTIONCODE, MATYPEMACHINETYPEICSTABLECODE, MACHINETYPEMACHINETYPECODE,
         MACHINENOMACHINENOICSTABLECODE, MACHINENOMACHINENOCODE, GRADEICSTABLECODE,
         GRADECODE, CADREICSTABLECODE, CADRECODE,
         DESGDESIGNATIONICSTABLECODE, DESGDESIGNATIONCODE, EMPROLECODE,
         SUBCTGSUBCATEGORYICSTABLECODE, SUBCATEGORYSUBCATEGORYCODE, FROMDATE,
         TODATE, CONFIRMATIONDATE, RESIGNDATE,
         JOININGDATE, p_creationtimestamp, serial_seq.nextval,
         ' ', ' ', sysdate,
         ' ', 0, 0,
         0
  from  employee;

由于ROW_NUMBER（）OVER来自双功能，因此缺少此函数的窗口规范并收到错误
