sql server2005数据库降到 sql server2000
各位：sql server2005数据库降到 sql server2000，除了在sql server2000下建立空库，除了用数据的导入的方法，数据库太多，另表之间的约束多，容易出错。有好的办法吗？

导脚本还不一定成功，2000到2005跨越太大，如果用到大量2005的新特性，你就惨了

另外，删除主键后，插入数据，然后再建立外键：
;WITH FK --外键约束
AS
(
SELECT
SCH.name as foreign_schema_name, --外键schema名
FK.name as foreign_name, --外键名
FK.is_disabled , --是否禁用
FK.delete_referential_action_desc as delete_action,
FK.update_referential_action_desc as update_action,
FKC.constraint_column_id, --约束列的id
FKC.parent_object_id, --父对象的id
FKC.parent_column_id, --父对象列的id
FKC.referenced_object_id, --被引用的对象
FKC.referenced_column_id --被引用的对象中的列
FROM sys.foreign_keys FK
INNER JOIN sys.foreign_key_columns FKC
ON FK.object_id = FKC.constraint_object_id
INNER JOIN sys.schemas SCH
ON FK.schema_id = SCH.schema_id
),
TB --表和列
AS
(
SELECT
TB.object_id,
SCH.name as schema_name,
TB.name as table_name,
C.column_id as column_id,
C.name as column_name
FROM sys.tables TB WITH(NOLOCK)
INNER JOIN sys.columns C WITH(NOLOCK)
ON TB.object_id = C.object_id
INNER JOIN sys.schemas SCH WITH(NOLOCK)
ON TB.schema_id = SCH.schema_id
WHERE TB.is_ms_shipped = 0 -- 此条件表示仅查询不是由内部 SQL Server 组件创建对象
)
SELECT
'alter table ['+TBP.schema_name+'].['+TBP.table_name+
'] add constraint ['+FK.foreign_name+'] '+
' foreign key('+TBP.column_name+') references [' +
TBR.schema_name +'].['+ TBR.table_name +']('+TBR.column_name+')'
as '新建外键索引,复制然后在运行'
FROM FK
INNER JOIN TB TBP
ON FK.parent_object_id = TBP.object_id
AND FK.parent_column_id = TBP.column_id
INNER JOIN TB TBR
ON FK.referenced_object_id = TBR.object_id
AND FK.referenced_column_id = TBR.column_id
/*

alter table [dbo].[tb_c] add constraint [FK__tb_c__idd__0A9D95DB] foreign key(idd) references [dbo].[tb_b](idd)
alter table [dbo].[tb_b] add constraint [FK__tb_b__id__05D8E0BE] foreign key(id) references [dbo].[tb](id)
