sql server 遊標fetch簡單用法

//遍歷tmp_check的年份和月份
DECLARE @year as varchar(4)
DECLARE @month as varchar(2)
DECLARE cur CURSOR FOR SELECT nf,yf FROM tmp_check;
OPEN cur 
fetch next from cur into @year,@month
while(@@fetch_status=0)
begin
print(@year)
print(@month)
//在這作其它的事
fetch next from cur into @year,@month
end close cur DEALLOCATE cur
