在PowerDesigner中，对SQL Server 2000进行数据库反向(Database -> Reverse Engineer Database)时，会反向出一些名称以“_WA_Sys”开头的索引，但这些索引并不是我们做数据库设计的时加的，如何去掉这些不必要的索引呢，请按如下步骤进行：
1、在PowerDesigner中点击Tools-Resources-DBMS，打开“List of DBMS”窗口
2、选择Microsoft SQL Server 2000，再点击窗口上的第一个按钮“Property”
3、从左侧树菜单中展开Script -> Objects -> Index，点击SqlListQuery，在右面的Memo编辑框里看到如下SQL语句：
{OWNER ID,
TABLE
ID,
INDEX
ID, CLUSTER ID,
UNIQUE
ID, CIDXLIST ...}
select
u.name,
o.name,
i.name,
case
(i.status
&
16
)
when
16
then
'
clustered
'
else
''
end
,
case
(i.status
&
2
)
when
2
then
'
unique
'
else
''
end
,
case
(k.keyno)
when
1
then
''
else
'
,
'
end
+
c.name
+
case
(Indexkey_Property(k.id,
k.indid, k.keyno,
'
IsDescending
'
))
when
1
then
'
desc
'
else
'
asc
'
end
from
sysusers u
join
sysobjects o
on
(o.uid
=
u.uid)
join
sysindexes i
on
(i.id
=
o.id)
join
sysindexkeys k
on
(k.id
=
i.id
and
k.indid
=
i.indid)
join
syscolumns c
on
(c.id
=
k.id
and
c.colid
=
k.colid)
where
i.indid
between
1
and
254
[
and o.name = %.q:TABLE%
]
[
and u.name = %.q:SCHEMA%
]
order
by
1
,
2
,
3
, k.keyno
4、在where i.indid between 1 and 254的下方加一句：
and i.name not like '%_WA_Sys%'
--用于过滤SQL Server自动创建的索引
5、保存即可
