以下以SQL Server 2000中的NorthWind數(shù)據(jù)庫中的Customers表為例,

用?臨時(shí)表 + While循環(huán)?的方法, 對(duì)Customers表中的CompanyName列進(jìn)行遍歷

create table?#temp

(

id?int?identity(1,1),

customer?nvarchar(50)

)

declare?@customer?nvarchar(50)

declare?@n????????int

declare?@rows?????int

select?@n=1

insert?#temp(customer)?select distinct?companyname?from?customers

select?@rows =?@@rowcount

while?@n <= @rows

begin

select?@customer = companyname

from?customers

where?companyname=(select customer?from?#temp?where?id = @n)

order by?companyname?desc

print(@customer)

select?@n = @n + 1

end

運(yùn)行后, 輸出結(jié)果如下:

(所影響的行數(shù)為 91 行)
