建立测试表，并插入测试数据
CREATE TABLE TEST_ROW_NUMBER_01(
CMZH varchar(10) not null,
CYLH varchar(10) null,
MJE money null,
);
INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES (2106000011,20281997,10.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000010,20281996,10.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000008,20281995,0.00) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000006,20281994,9.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000004,20281993,5.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000001,20281992,10.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000002,20281992,10.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000007,20217280,0.00) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000009,20172458,5.50) INSERT INTO TEST_ROW_NUMBER_01(CMZH,CYLH,MJE) VALUES(2106000005,20121813,0.00) 执行脚本自动生成行号并按CYLH进行排序（滑动查看代码） SELECT ROW_NUMBER()OVER(ORDER BY CYLH DESC) AS ROWNUM,* FROM TEST_ROW_NUMBER_01 结果如下： 注意：在使用 到此这篇关于SQL使用ROW_NUMBER() OVER函数生成序列号的文章就介绍到这了,更多相关SQL用ROW_NUMBER() OVER生成序列号内容请搜索极客世界以前的文章或继续浏览下面的相关文章希望大家以后多多支持极客世界！ |
