Is there a SQLite version of the LinqPad nutshell database

由 ≡放荡痞女 提交于 2021-02-07 09:34:20
问题 I am trying to learn LINQ with LINQPad, but the fact is that I have a notebook. Therefore, I don't want to install SQL Server on it (I am not even conviced that I could do it). Some LINQPAD Examples use a database called nutshell.mdf, I'd like to know if I can find a SQLite version of this database, and where? 回答1: There's no SQLite version, but you can create a SQL CE edition easily enough. SQL CE is fairly lightweight and won't bog down your notebook. LINQPad supports SQL CE: click "Add

26.没有ldf的mdf附加数据库--2013-06-07

今天有个老数据库要查看下，想把它附加到sqlserver2005中，但是发现ldf不见了，一直出错。找了下别人的方法 只有一个mdf文件如Test.mdf,附加数据库 1.在SQL Server中新建一个数据库名为Test（注，文件名为Test.mdf真正的的数据库不一定是这个名，先在SQL Server中导入过程中看看是不是这个名，一定要和真正的数据库名称一致） 2.停止SQL Server,把Test.mdf替换掉 3.重新启动SQL Server,如果你点一下Test数据库会有错误提示,不用管它 4.打开一查询窗口,进行以下操作: ①alter database Test set emergency 设定Test状态为紧急模式 ②sp_dboption 'Test','single user','false' 设定数据库模式为"单一使用者" ③dbcc checkdb(Test,repair_allow_data_loss) 此句为关键语句,意为检查指定数据库所有数据的配置、结构和逻辑完整性。这一步操作会重新建立ldf日志文件 ④sp_dboption 'Test','single user','false' 还原Test数据库模式 ⑤alter database Test set online 设定Test数据库状态为online 注第③步很多人不会成功，原因在于
