用脚本删除数据库要容易得多(甚至可能更快)，然后直接从脚本中删除并创建数据库。

这是数据库擦除脚本之王。它将清除所有表并正确地重新播种:

SET QUOTED_IDENTIFIER ON;
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER TABLE ? NOCHECK CONSTRAINT ALL'  
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER TABLE ? DISABLE TRIGGER ALL'  
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON; DELETE FROM ?'  
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER TABLE ? CHECK CONSTRAINT ALL'  
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON; ALTER TABLE ? ENABLE TRIGGER ALL' 
EXEC sp_MSforeachtable 'SET QUOTED_IDENTIFIER ON';

IF NOT EXISTS (
    SELECT
        *
    FROM
        SYS.IDENTITY_COLUMNS
        JOIN SYS.TABLES ON SYS.IDENTITY_COLUMNS.Object_ID = SYS.TABLES.Object_ID
    WHERE
        SYS.TABLES.Object_ID = OBJECT_ID('?') AND SYS.IDENTITY_COLUMNS.Last_Value IS NULL
)
AND OBJECTPROPERTY( OBJECT_ID('?'), 'TableHasIdentity' ) = 1

    DBCC CHECKIDENT ('?', RESEED, 0) WITH NO_INFOMSGS;

享受吧，但要小心!

对于SQL 2005，

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?'

2000年和2005/2008年的链接更多。

用脚本删除数据库要容易得多(甚至可能更快)，然后直接从脚本中删除并创建数据库。

截断所有表最困难的部分是删除和读取外键约束。

下面的查询为与@myTempTable中的每个表名相关的每个约束创建了drop & create语句。如果希望为所有表生成这些表名，可以简单地使用信息模式来收集这些表名。

DECLARE @myTempTable TABLE (tableName varchar(200))
INSERT INTO @myTempTable(tableName) VALUES
('TABLE_ONE'),
('TABLE_TWO'),
('TABLE_THREE')


-- DROP FK Contraints
SELECT 'alter table '+quotename(schema_name(ob.schema_id))+
  '.'+quotename(object_name(ob.object_id))+ ' drop constraint ' + quotename(fk.name) 
  FROM sys.objects ob INNER JOIN sys.foreign_keys fk ON fk.parent_object_id = ob.object_id
  WHERE fk.referenced_object_id IN 
      (
         SELECT so.object_id 
         FROM sys.objects so JOIN sys.schemas sc
         ON so.schema_id = sc.schema_id
         WHERE so.name IN (SELECT * FROM @myTempTable)  AND sc.name=N'dbo'  AND type in (N'U'))


 -- CREATE FK Contraints
 SELECT 'ALTER TABLE [PIMSUser].[dbo].[' +cast(c.name as varchar(255)) + '] WITH NOCHECK ADD CONSTRAINT ['+ cast(f.name as varchar(255)) +'] FOREIGN KEY (['+ cast(fc.name as varchar(255)) +'])
      REFERENCES [PIMSUser].[dbo].['+ cast(p.name as varchar(255)) +'] (['+cast(rc.name as varchar(255))+'])'
FROM  sysobjects f
      INNER JOIN sys.sysobjects c ON f.parent_obj = c.id
      INNER JOIN sys.sysreferences r ON f.id = r.constid
      INNER JOIN sys.sysobjects p ON r.rkeyid = p.id
      INNER JOIN sys.syscolumns rc ON r.rkeyid = rc.id and r.rkey1 = rc.colid
      INNER JOIN sys.syscolumns fc ON r.fkeyid = fc.id and r.fkey1 = fc.colid
WHERE 
      f.type = 'F'
      AND
      cast(p.name as varchar(255)) IN (SELECT * FROM @myTempTable)

然后，我只是复制语句来运行—但是稍加开发工作，您就可以使用游标来动态地运行它们。

select 'delete from ' +TABLE_NAME from INFORMATION_SCHEMATABLE_TYPE='BASE TABLE'的表

结果就在那里。

在查询窗口复制粘贴并运行命令
