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
