在SMO(C#)中,等同于......
ALTER DATABASE db SET HADR OFF;
我已经查看了Database和AvailabilityDatabase类的文档,但没有任何内容真正跳出来。
此处的最终目标是删除作为可用性组成员的数据库。目前,我们首先关闭HADR,然后在所有辅助服务器上删除数据库,然后在主服务器上从可用性组中删除数据库并将数据库放在那里。

以下是我使用SMO删除加入AlwaysOn可用性组的数据库的过程......
Server primaryServer = new Server();
AvailabilityDatabase pDb = primaryServer.AvailabilityGroups[agName].AvailabilityDatabases[dbName];
pDb.SuspendDataMovement();
while (!pDb.IsSuspended)
{
Thread.Sleep(1000);
pDb.Refresh();
}
foreach (var secondary in secondaryServers)
{
AvailabilityDatabase sDb = secondary.AvailabilityGroups[agName].AvailabilityDatabases[dbName];
sDb.SuspendDataMovement();
while (!sDb.IsSuspended)
{
Thread.Sleep(1000);
sDb.Refresh();
}
sDb.LeaveAvailabilityGroup(); // this appears to be the equivalent of SET HADR OFF
Database db = secondary.Databases[dbName];
db.UserAccess = DatabaseUserAccess.Single;
secondary.KillAllProcesses(dbName);
db.Drop();
}
pDb.Drop();
Database db = primaryServer.Databases[dbName];
db.UserAccess = DatabaseUserAccess.Single;
primaryServer.KillAllProcesses(dbName);
db.Drop();
