关于简单的一条sql查询语句
select x.tno,x.score as xscore,y.score as yscore from evaluate as x,evaluate as y where (x.score>y.score) and (y.tno='14')
如上查询语句为表的自身连接查询语句，但是sql报错了，内容为sql命令未正确结束，为什么？求高手指教！
[解决办法]
测试了一下，没问题啊，是不是不仅仅只有这语句？

--> 测试数据：[evaluate]
if object_id('[evaluate]') is not null drop table [evaluate]
go
create table [evaluate]([tno] int,[score] int)
insert [evaluate]
select 1,123 union all
select 14,12312 union all
select 2,452314
--------------开始查询--------------------------
select x.tno,x.score as xscore,y.score as yscore from evaluate as x,evaluate as y where (x.score>y.score) and (y.tno='14')
----------------结果----------------------------
/*
tno xscore yscore
----------- ----------- -----------
2 452314 12312
*/
--没有问题啊，有可能是全角空格造成的，试试下面的
select x.tno,x.score as xscore,y.score as yscore
from evaluate as x,evaluate as y
where x.score>y.score and y.tno='14'
x.score AS xscore ,
y.score AS yscore
FROM evaluate x , --把as 去掉
evaluate y
WHERE ( x.score > y.score )
AND ( y.tno = '14' )
