查询两表不同记录
例:
如:tableA
id name age
1 aa 22
2 bb 33
3 cc 42
4 dd 55
5 gg 32
6 ff 88

tableB
id name age
1 aa 22
2 bb 33
3 cc 44
4 dd 55
5 ee 66
6 ff 77

希望查出结果:
cc
gg
ee
ff
就是说两个表中只要有一个字段不同就取出它的name不要重复的．谢谢．．．

[解决办法]
select
a.name
from
tableA a
where
exists(select 1 from tableB where name=a.name and (age!=a.age or id!=a.id))
or
not exists(select 1 from tableB where name=a.name)
union
select b.name from tableB b where not exists(select 1 from tableA where name=b.name)
[解决办法]
select distinct isnull(A.name,B.name)

from A
full join B on isnull(A.name, ' ')=isnull(B.name, ' ')
where isnull(A.age,0) <> isnull(B.age,0)
