use test; --创建测试表 create table test ( id int primary key identity, name varchar(20) not null ); --插入数据 insert into test(name) values('test1'); insert into test(name) values('test2'); insert into test(name) values('test3'); insert into test(name) values('test4'); insert into test(name) values('test5'); insert into test(name) values('test6'); insert into test(name) values('test7'); insert into test(name) values('test8'); insert into test(name) values('test9'); insert into test(name) values('test10'); select * from test; --执行分页 SELECT TOP 10 id,name FROM test WHERE id NOT IN (SELECT TOP (10 * 0) id FROM test ORDER BY id) ORDER BY ID select id,name from test; --select top pageSize * from tableName where id not in (select top pageSize * (pageNow - 1) id from tableName);

小技巧
快速插入数据:
insert into test(name) select name from test;
总结语法
SELECT TOP页大小 *
FROM TestTable
WHERE (ID NOT IN
(SELECT TOP页大小 * 页数 id
FROM表
ORDER BY id))
ORDER BY ID
select top pageSize * from tableName where id not in (select top pageSize * (pageNow - 1) id from tableName);
pageNow:当前第几页
pageSize:每页显示的记录数
