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

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'

您必须首先禁用所有触发器和约束。

EXEC sp_MSforeachtable @command1="ALTER TABLE ? NOCHECK CONSTRAINT ALL"

EXEC sp_MSforeachtable @command1="ALTER TABLE ? DISABLE TRIGGER ALL"

在此之后，您可以生成用于删除对象的脚本

SELECT 'Drop Table '+name FROM sys.tables WHERE type='U';

SELECT 'Drop Procedure '+name FROM  sys.procedures WHERE type='P';

执行生成的语句。

最好的方法是“为Drop生成脚本”

选择数据库->右键单击->任务->生成脚本-将打开生成脚本的向导

在set Scripting选项中选择对象后，单击高级按钮

设置选项“Script to create”为true(想要创建) 设置选项“Script to Drop”为true(想要删除) ->选中复选框，选择要创建脚本的对象 ->选择写脚本的选项(文件，新建窗口，剪贴板) 默认情况下，它包含依赖对象。(并将首先删除约束) 执行脚本

这样我们就可以自定义脚本。

试试这个…

USE DATABASE
GO
DECLARE @tname VARCHAR(150)
DECLARE @strsql VARCHAR(300)

SELECT @tname = (SELECT TOP 1 [name] FROM sys.objects WHERE [type] = 'U' and [name] like N'TableName%' ORDER BY [name])

WHILE @tname IS NOT NULL
BEGIN
    SELECT @strsql = 'DROP TABLE [dbo].[' + RTRIM(@tname) +']'
    EXEC (@strsql)
    PRINT 'Dropped Table : ' + @tname
    SELECT @tname = (SELECT TOP 1 [name] FROM sys.objects WHERE [type] = 'U' AND [name] like N'TableName%'  AND [name] > @tname ORDER BY [name])
END

这个脚本清除所有视图，SPS，函数pk, fk和表。

/* Drop all non-system stored procs */

DECLARE @SQL VARCHAR(254)

SELECT @name = (SELECT TOP 1 [name] FROM sysobjects WHERE [type] = 'P' AND category = 0 ORDER BY [name])

    SELECT @SQL = 'DROP PROCEDURE [dbo].[' + RTRIM(@name) +']'
    EXEC (@SQL)
