在mysql中create view as 怎样写sql语句

-- 请修改  view_name 和 table_name 名称
create view view_name as
select * from table_name

几个简单的基本的sql语句
选择：select * from table1 where 范围
插入：insert into
table1(field1,field2) values(value1,value2)
删除：delete from table1 where 范围

更新：update table1 set field1=value1 where 范围
查找：select * from table1
where field1 like '%value1%' ---like的语法很精妙，查资料!
排序：select * from table1
order by field1,field2 [desc]
总数：select count as totalcount from table1

求和：select sum(field1) as sumvalue from table1
平均：select avg(field1) as
avgvalue from table1
最大：select max(field1) as maxvalue from table1

最小：select min(field1) as minvalue from table1
