sql server 循环操作

使用的sql 语句如下：

declare
@userid int ;
set @userid=0
while(@userid<20)
begin

print 'the result is :'+STR(@userid);
set @userid=@userid+1;
end

测试的结果如下：

the result is :         0
the result is :         1
the result is :         2
the result is :         3
the result is :         4
the result is :         5
the result is :         6
the result is :         7
the result is :         8
the result is :         9
the result is :        10
the result is :        11
the result is :        12
the result is :        13
the result is :        14
the result is :        15
the result is :        16
the result is :        17
the result is :        18
the result is :        19

还是比较简单的，但是相对于oracle 没有for 循环 感觉还是不太方便
