select * from 20080421
union select * from 20080421
union select * from 20080420
union select * from 20080419
union select * from 20080418
union select * from 20080417
union select * from 20080416
union select * from 20080415
union select * from 20080414
UNION select * from 20080413;

这个语句执行的时候,提示定义了过多字段.
