几个简单的基本的sql语句 选择:select * from table1 where id > 0 插入:insert into table1(field1,field2) values(value1,value2) 删除:delete from table1 where id > 0 更新:update table1 set field1=value1 where id > 0 查找:select * from table1 where field1 like ’%value1%’ 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
