[转]sql利用游标循环,遍历表循环结果集

用  游标(Cursor) + While循环 的方法, 对Customers表中的CompanyName列进行遍历

declare @customer nvarchar(50)

declare pcurr cursor for
select distinct companyname from customers

open pcurr
fetch next from pcurr into @customer

while (@@fetch_status = 0)
begin

 print (@customer)
 fetch next from pcurr into @customer

end

close pcurr
deallocate pcurr
