大家好，我是天空之城，今天给大家带来，mysql数据库查询结果的排序和分页

#order by 排序语法
SELECT column name1, column name2
FROM table name1, table name2
ORDER BY column name, column name [ASCIDESC]

ASC表示升序排列，DESC表示降序排列
默认情况下是升序排列

#limit分页语法
SEL .ECT column name1, column name2
FROM table name1, table name2
LIMIT [offset,] row_ count

offset指定要返回的第一行（第一条数据）的偏移量，第一行的偏移量是0，而不是1
row_count指定要返回的最大行数

还是按照之前employee表进行练习
select * from employee order by salary;
工资按照升序排列
select * from employee order by salary desc;
降序排列

同时按照两个条件进行排序
select * from employee order by sex, salary desc;
结果如下

继续

select * from employee limit 5;显示五条数据

分页显示
select * from employee limit 0,5;
select * from employee limit 5,5;
select * from employee limit 10,5;
