Sql 循环

declare 
    --创建游标
    cur cursor for select _user,_pwd from userTable;
declare

    @use varchar(20),@pw varchar(20);
    begin
    --打开游标
    open cur;
    --移动游标取值
    fetch next from cur into @use,@pw;
    --这里对游标的状态进行判断，如果为0，证明游标中有值
    while @@FETCH_STATUS = 0
        begin
            print(@use);
            print(@pw);
            --让游标继续往后移动
            fetch next from cur into @use,@pw
        end
    --关闭游标
    close cur;
    deallocate cur;
    end

	DECLARE @i INT = 0; --设置循环次数起始值
WHILE @i < 100 --200是循环终止次数
BEGIN
print (@)
SET @i = @i + 1;
END;
