世界银行怎么查商品贸易量

世界银行查商品贸易量方法：世界银行直接在商品贸易行里面查商品贸易量就可以了，而且里面有商品贸易量数据，直接在里面查询账单就可以。世界银行也可以直接打开电脑，然后直接在商品贸易商城里面查找商品贸易量就可以了

我来帮你回答吧

第一句的查询语句是“select max(avg (价格)) from 商品表1”

第二句的查询语句是“select avg(数量)from 商品表1 order by avg 数量 desc where 分类名＝？ ”

第三句是“select 单价>2000 or 数量>=15 from 商品表1”

1、首先打开SQL Server Management管理工具，运用Select语句查询出要排序的数据，如下图所示。

2、接下来直接运用Order By对数据中的ContactName字段进行排序，如下图所示，默认是升序。

3、如果想按照降序的话，则需要在排序字段后面加上desc属性，如下图所示。

4、接下来也可以在order by后面加上两个或者多个字段，如下图所示，SQL Server会按照他们的顺序组合进行排序。

5、如果想对ContactName进行升序，对CustomerID进行降序，则可以安装如下图所示的方式书写。

1

select from good order by price

2

select cid from SalesRecorder where gid='1002'

3

select count(distinct cid) from SalesRecorder

4

select count() from Customer where sex='男'

5

select avg(to_number(to_char(sysdate,'yyyy'))-to_number(to_char(birth,'yyyy'))) from Customer where sex='男'

6

select cid,cname from Customer

where cid in

(select cid from SalesRecorder where gid in('1002','1006'))

7

select cname from Customer

where cid not in (select cid from SalesRecorder)

8

select max(quantity) from SalesRecorder where gid='1001'

9

select cname from Customer where cid in

(select cid from SalesRecorder where gid='1001'

and quantity=(select max(quantity) from SalesRecorder where gid='1001'))

10

select cid from SalesRecorder where gid in

(select gid from Good where price<100)

11

select cid from SalesRecorder where gid not in

(select gid Good where price<100)

12

select cname from Customer where cid in

(select cid from SalesRecorder where gid not in

(select gid Good where price<100))

13

select bgid,bgname

from Customer a,Good b,SalesRecorder c

where acid=ccid and bgid=cgid

and asex='女'

group by bgid,bgname

14

select bgid,bgname,sum(cquantity)

from Customer a,Good b,SalesRecorder c

where acid=ccid and bgid=cgid

and asex='女'

group by bgid,bgname

15

select bgname,bprice

from Customer a,Good b,SalesRecorder c

where acid=ccid and bgid=cgid

and (to_number(to_char(sysdate,'yyyy'))-to_number(to_char(abirth,'yyyy')))

between 20 and 25

group by bgname,bprice

16

select t from

(select bgid,bgname,sum(cquantity) quantity

from Customer a,Good b,SalesRecorder c

where acid=ccid and bgid=cgid

group by bgid,bgname)

order by tquantity desc

17

select from Good where gid not in

(select gid from SalesRecorder)

18

delete from Good where gid not in

(select gid from SalesRecorder)

19

update Good set price=price(1-01) where gid in

(select t1gid from

(select tgid,tquantity,row_number() over order by (quantity) rn

from

(select gid,sum(quantity) quantity from SalesRecorder group by gid) t) t1

where rn between 1 and 2)

写的太急，可能多少有点错误，自己能改就自己改了吧

priavte sub text1_change()

dim rs as new adodbrecordset

dim sql as string

sql = "select name from tb where id ='" & text1text & "'"

rsopen sql,cnn

if rseof then

text2text=""

else

text2text=rs(0)

endif

rsclose

end sub

说实在的没有理解问题。

猜测答案：

目测类别表有点像N级目录，t_uid对应了商品所归属的目录。所以

select from [商品详情表] where t_uid in (3,4,5,6,)

省略号表示你有多少包含男装字样的uid 都加进去

select item_code,barcode from item

where description like '%可口可乐%';

select sum(sales_value)salevalue,sum(sales_unit) salesl

from sales where to_char(period,'yyyymm')='200907' order by 1
