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。

这就是我所尝试的:

SELECT 'DROP TABLE [' + SCHEMA_NAME(schema_id) + '].[' + name + ']' FROM sys.tables

无论输出什么，它将打印，只是复制和粘贴在新的查询和按执行。 这将删除所有表。

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'

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])

    END

END
GO

/* Drop all Primary Key constraints */
DECLARE @name VARCHAR(128)

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

    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')
