use J190802

【使用J190802表】

1、创建表tbfact表，表结构是：

id int primary key 自动增长

r1 int

r2 int

r3 int

r4 int

r5 int

r6 int

b7 int

qs varchar(7)

create table tbfact(

id int primary key auto_increment,

r1 int,

r2 int,

r3 int,

r4 int,

r5 int,

r6 int,

b7 int,

qs varchar(7)

);

2、将tb_fact.sql中的所有数据插入到tbfact表中。

1、查询2010年的所有数据。

select * from tbfact where  qs  like '2010%'

2、查询2005年到2007年的b7列的所有数据。

select b7 from tbfact where  qs like  '2005%' or qs like  '2006%' or qs like  '2007%'

3、统计b7列中出现的数值以及各数值出现的次数。

select b7 , count(b7) from tbfact   group by b7

4、显示表中r1到r6的和值(每行的和)以及期数。

select (r1+r2+r3+r4+r5+r6) , qs  from tbfact
