mysql 和并列

kicked off Wednesday in the northea

直接在语句后面写order by 得分这个字段,

select * from message where (typeid=31) or (typeid=30) or (typeid=32) or (typeid=33) order by id desc; 或者 select * from message where typeid IN ( 31, 30, 32, 33) order by id desc;

select * from (select Student.S#,Sname,Sage,Ssex,SC.C#,score,Cname from SC inner join Student on SC.S#=Student.S# inner join Course on Course.C#=SC.C#) as t where exists( select count(1) from t as d where C#=d.C# and score < d....

select t1.name,t2.name,t3.name from table1 t1,table2 t2,table3,t3 where t1.id=t2.id and t1.id=t3.id limit 1,3 就是这个样子了,mysql的分页最好写了

mysql> show table status like 'tb%'\G*************************** 1. row *************************** Name: tb_account Engine: InnoDB Version: 10 Row_format: Compact Rows: 27010 Avg_row_length: 175 Data_length: 4734976Max_data_le...

where后加多个条件可以用and来连接。 如,student表中有如下数据: 现在要查,sex为男,age为20的...

首先 判断 变量 是否存在,然后动态生成 sql 查询条件。 php 类似代码如下:

ORDER BY 成绩 DESC,时间 DESC

select s.id,s.name,s.score,s.kemu, (select count(1) + 1 from score sc where sc.kemu = s.kemu and sc.score > s.score) as mingci /*分数相同,名次并列*/ from score s where 1 = 1 /* and s.name = 'uOXd' and s.kemu in ('R','L','W','S'...
