SMO学习笔记（四）——分离数据库

SQL Server Management Studio演示分离数据库：
 

1.选择要分离的数据库，右键选择分离。 

 

2.确认分离。
 

 

SMO分离数据库代码：
 

         ///   <summary>
         ///  分离数据库
         ///   </summary>
         ///   <param name="SmoParm"></param>
         public   static   void  DetachDatabase( string  SqlConnectionString)
        {
             using  (SqlConnection Connection  =   new  SqlConnection(SqlConnectionString))
            {
                Server server  =   new  Server( new  ServerConnection(Connection));
                 // test为数据库的名称
                Database currentDb  =  server.Databases[ " test " ];

                 // 看是否数据库已经存在
                 if  (currentDb  !=   null )
                {
                    Connection.ChangeDatabase( " test " );

                    server.KillAllProcesses( " test " );

                    currentDb.DatabaseOptions.UserAccess  =  DatabaseUserAccess.Single;

                    currentDb.Alter(TerminationClause.RollbackTransactionsImmediately);

                    server.DetachDatabase( " test " ,  true );                 }             }         }
