select*from shuiguo 查询表

select * from shuiguo where jiage between 5 and 7（between表示大于等于5且小于等于7的范围）

select distinct name from shuiguo--去除重复，只针对一列

select * from shuiguo where name='苹果' and chandi='海南'

select * from shuiguo where name in('苹果','香蕉')--name只包含苹果，香蕉的

select * from shuiguo where name not in('苹果','香蕉')--name中除了苹果，香蕉的

select * from shuiguo where name like '%苹%'--模糊查询，%叫通配符（%在前面表示前面有任何字符，%在后面表示后面有任何字符）

select * from shuiguo where name like '苹_'--下划线表示任意一个字符

select * from shuiguo order by jiage--升序排列

select * from shuiguo order by jiage desc --降序排列

select top 2* from shuiguo order by jiage--按升序排列，只取前两行（top 2）

select top 1 * from shuiguo where name='苹果' order by jiage desc--按照条件查询后排序，查名字叫苹果的谁的价格高，只选第一个

delete from shuiguo where chandi='烟台' --删除水果表中产地是烟台的数据

alter table shuiguo add dianhua int --添加列名电话

update shuiguo set dianhua= 2255557 where code=2 --定义第几行的电话是多少

修改表加入新列 　　alter table abc add dianhua int

修改表删除一列 　　alter table abc drop column dianhua
