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

为了补充Ivan的回答，我还需要删除所有用户定义的类型，所以我在脚本中添加了以下内容:

/* Drop all user-defined types */
DECLARE @name VARCHAR(128)
DECLARE @SQL VARCHAR(254)

SELECT @name = (select TOP 1 [name] from sys.types where is_user_defined = 1)

WHILE @name IS NOT NULL
BEGIN
    SELECT @SQL = 'DROP TYPE [dbo].[' + RTRIM(@name) +']'
    EXEC (@SQL)
    PRINT 'Dropped Type: ' + @name
    SELECT @name = (select TOP 1 [name] from sys.types where is_user_defined = 1)
END
GO

我正在使用Adam Anderson编写的脚本，该脚本已更新为支持dbo以外的其他模式中的对象。

declare @n char(1)
set @n = char(10)

declare @stmt nvarchar(max)

-- procedures
select @stmt = isnull( @stmt + @n, '' ) +
    'drop procedure [' + schema_name(schema_id) + '].[' + name + ']'
from sys.procedures


-- check constraints
select @stmt = isnull( @stmt + @n, '' ) +
'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + ']    drop constraint [' + name + ']'
from sys.check_constraints

-- functions
select @stmt = isnull( @stmt + @n, '' ) +
    'drop function [' + schema_name(schema_id) + '].[' + name + ']'
from sys.objects
where type in ( 'FN', 'IF', 'TF' )

-- views
select @stmt = isnull( @stmt + @n, '' ) +
    'drop view [' + schema_name(schema_id) + '].[' + name + ']'
from sys.views

-- foreign keys
select @stmt = isnull( @stmt + @n, '' ) +
    'alter table [' + schema_name(schema_id) + '].[' + object_name( parent_object_id ) + '] drop constraint [' + name + ']'
from sys.foreign_keys

-- tables
select @stmt = isnull( @stmt + @n, '' ) +
    'drop table [' + schema_name(schema_id) + '].[' + name + ']'
from sys.tables

-- user defined types
select @stmt = isnull( @stmt + @n, '' ) +
    'drop type [' + schema_name(schema_id) + '].[' + name + ']'
from sys.types
where is_user_defined = 1


exec sp_executesql @stmt

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'

尝试使用sql2012或更高版本，

这将有助于删除所选架构的所有对象

DECLARE @MySchemaName VARCHAR(50)='dbo', @sql VARCHAR(MAX)='';
DECLARE @SchemaName VARCHAR(255), @ObjectName VARCHAR(255), @ObjectType VARCHAR(255), @ObjectDesc VARCHAR(255), @Category INT;

DECLARE cur CURSOR FOR
    SELECT  (s.name)SchemaName, (o.name)ObjectName, (o.type)ObjectType,(o.type_desc)ObjectDesc,(so.category)Category
    FROM    sys.objects o
    INNER JOIN sys.schemas s ON o.schema_id = s.schema_id
    INNER JOIN sysobjects so ON so.name=o.name
    WHERE s.name = @MySchemaName
    AND so.category=0
    AND o.type IN ('P','PC','U','V','FN','IF','TF','FS','FT','PK','TT')

OPEN cur
FETCH NEXT FROM cur INTO @SchemaName,@ObjectName,@ObjectType,@ObjectDesc,@Category

SET @sql='';
WHILE @@FETCH_STATUS = 0 BEGIN    
    IF @ObjectType IN('FN', 'IF', 'TF', 'FS', 'FT') SET @sql=@sql+'Drop Function '+@MySchemaName+'.'+@ObjectName+CHAR(13)
    IF @ObjectType IN('V') SET @sql=@sql+'Drop View '+@MySchemaName+'.'+@ObjectName+CHAR(13)
    IF @ObjectType IN('P') SET @sql=@sql+'Drop Procedure '+@MySchemaName+'.'+@ObjectName+CHAR(13)
    IF @ObjectType IN('U') SET @sql=@sql+'Drop Table '+@MySchemaName+'.'+@ObjectName+CHAR(13)

    --PRINT @ObjectName + ' | ' + @ObjectType
    FETCH NEXT FROM cur INTO @SchemaName,@ObjectName,@ObjectType,@ObjectDesc,@Category
END
CLOSE cur;    
DEALLOCATE cur;
SET @sql=@sql+CASE WHEN LEN(@sql)>0 THEN 'Drop Schema '+@MySchemaName+CHAR(13) ELSE '' END
PRINT @sql
--EXECUTE (@sql)

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'
