还有一个样本

declare @objectId int,  @objectName varchar(500), @schemaName varchar(500), @type nvarchar(30), @parentObjId int, @parentObjName nvarchar(500)
declare cur cursor 
for 

select obj.object_id, s.name as schema_name, obj.name, obj.type, parent_object_id
from sys.schemas s
    inner join sys.sysusers u
        on u.uid = s.principal_id
        JOIN
        sys.objects obj on obj.schema_id = s.schema_id
WHERE s.name = 'schema_name' and (type = 'p' or obj.type = 'v' or obj.type = 'u' or obj.type = 'f' or obj.type = 'fn')

order by obj.type

open cur
fetch next from cur into @objectId, @schemaName, @objectName,  @type, @parentObjId
while @@fetch_status = 0
begin
    if @type = 'p'
    begin
        exec('drop procedure ['+@schemaName +'].[' + @objectName + ']')
    end

    if @type = 'fn'
    begin
        exec('drop FUNCTION ['+@schemaName +'].[' + @objectName + ']')
    end

    if @type = 'f'
    begin
        set @parentObjName = (SELECT name from sys.objects WHERE object_id = @parentObjId)
        exec('ALTER TABLE ['+@schemaName +'].[' + @parentObjName + ']' + 'DROP CONSTRAINT ' +  @objectName)
    end

    if @type = 'u'
    begin
        exec('drop table ['+@schemaName +'].[' + @objectName + ']')
    end

    if @type = 'v'
    begin
        exec('drop view ['+@schemaName +'].[' + @objectName + ']')
    end
    fetch next from cur into  @objectId, @schemaName, @objectName,  @type, @parentObjId
end
close cur
deallocate cur

备份一个完全空的数据库。不需要删除所有对象，只需恢复备份。

试试这个

Select 'ALTER TABLE ' + Table_Name  +'  drop constraint ' + Constraint_Name  from Information_Schema.CONSTRAINT_TABLE_USAGE

Select 'drop Procedure ' + specific_name  from Information_Schema.Routines where specific_name not like 'sp%' AND specific_name not like 'fn_%'

Select 'drop View ' + table_name  from Information_Schema.tables where Table_Type = 'VIEW'

SELECT 'DROP TRIGGER ' + name FROM sysobjects WHERE type = 'tr'

Select 'drop table ' + table_name  from Information_Schema.tables where Table_Type = 'BASE TABLE'

没有一种单一的说法可以用来实现这一目标。

当然，您可以自己创建一个存储过程，用于执行这些不同的管理任务。

然后可以使用这条语句执行过程。

Exec sp_CleanDatabases @DatabaseName='DBname'

这个脚本清除所有视图，SPS，函数pk, fk和表。

在我看来这是一个相当危险的功能。如果你要实现这样的东西，我会确保以一种你不能每次事故都运行它的方式正确地保护它。

如前所述，您可以自己创建某种存储过程。 在SQL Server 2005中，您可以查看这个系统表来确定和查找您想要删除的对象。

select * from sys.objects
