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'

我在这里尝试了一些脚本，但它们不适合我，因为我的表是模式中的。所以我整理了以下内容。注意，这个脚本接受一个模式列表，然后按顺序删除。您需要确保您的模式有一个完整的顺序。如果存在任何循环依赖关系，那么它将失败。

PRINT 'Dropping whole database'

DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR

SET @Cursor = CURSOR FAST_FORWARD FOR

DECLARE @schemas as varchar(1000) = 'StaticData,Ird,DataImport,Collateral,Report,Cds,CommonTrade,MarketData,TypeCode'
DECLARE @schemasXml as xml = cast(('<schema>'+replace(@schemas,',' ,'</schema><schema>')+'</schema>') as xml)

DECLARE @Sql NVARCHAR(500) DECLARE @Cursor CURSOR

SET @Cursor = CURSOR FAST_FORWARD FOR
SELECT sql = 'DROP SCHEMA ['+schemaName+']' FROM 
(SELECT CAST(T.schemaName.query('text()') as VARCHAR(200)) as schemaName FROM @schemasXml.nodes('/schema') T(schemaName)) as X

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

DECLARE @name VARCHAR(255)
DECLARE @type VARCHAR(10)
DECLARE @prefix VARCHAR(255)
DECLARE @sql VARCHAR(255)

DECLARE curs CURSOR FOR
SELECT [name], xtype
FROM sysobjects
WHERE xtype IN ('U', 'P', 'FN', 'IF', 'TF', 'V', 'TR') -- Configuration point 1
ORDER BY name

OPEN curs
FETCH NEXT FROM curs INTO @name, @type

WHILE @@FETCH_STATUS = 0
BEGIN
-- Configuration point 2
SET @prefix = CASE @type
WHEN 'U' THEN 'DROP TABLE'
WHEN 'P' THEN 'DROP PROCEDURE'
WHEN 'FN' THEN 'DROP FUNCTION'
WHEN 'IF' THEN 'DROP FUNCTION'
WHEN 'TF' THEN 'DROP FUNCTION'
WHEN 'V' THEN 'DROP VIEW'
WHEN 'TR' THEN 'DROP TRIGGER'
END

SET @sql = @prefix + ' ' + @name
PRINT @sql
EXEC(@sql)
FETCH NEXT FROM curs INTO @name, @type
END

CLOSE curs
DEALLOCATE curs

删除所有表:

exec sp_MSforeachtable 'DROP TABLE ?'

当然，这将删除除存储过程之外的所有约束、触发器等。

对于存储过程，恐怕您将需要存储在master中的另一个存储过程。
