SQL Server 2017 SQLPS执行Add-SqlAvailabilityDatabase遇到问题
这个错误简直逆天，查了下该cmdlet的帮助
常规参数里有Debug。
执行Debug，输出如下：
PS C:\Windows\system32> Add-SqlAvailabilityDatabase -InputObject $ag -Database $DatabaseList -Debug

将相关语句单独提取出来执行：
select * into #tmpag_availability_groups from master.sys.availability_groups select agstates.group_id, agstates.primary_replica into #tmpag_availability_group_states from master.sys.dm_hadr_availability_group_states as agstates select group_id, replica_id, replica_metadata_id into #tmpag_availability_replicas from master.sys.availability_replicas select replica_id, is_local, role into #tmpag_availability_replica_states from master.sys.dm_hadr_availability_replica_states SELECT AG.name AS [Name], AG.group_id AS [UniqueId], ISNULL(AG.automated_backup_preference, 4) AS [AutomatedBackupPreference], ISNULL(AG.failure_condition_level, 6) AS [FailureConditionLevel], ISNULL(AG.health_check_timeout, -1) AS [HealthCheckTimeout], ISNULL(agstates.primary_replica, '') AS [PrimaryReplicaServerName], ISNULL(arstates2.role, 3) AS [LocalReplicaRole], AR2.replica_metadata_id AS [ID], ISNULL(AG.basic_features, 0) AS [BasicAvailabilityGroup], ISNULL(AG.db_failover, 0) AS [DatabaseHealthTrigger], ISNULL(AG.dtc_support, 0) AS [DtcSupportEnabled], ISNULL(AG.is_distributed, 1) AS [IsDistributedAvailabilityGroup], ISNULL(AG.cluster_type, 0) AS [ClusterType], ISNULL(AG.required_copies_to_commit, 0) AS [RequiredCopiesToCommit] FROM #tmpag_availability_groups AS AG LEFT OUTER JOIN #tmpag_availability_group_states as agstates ON AG.group_id = agstates.group_id INNER JOIN #tmpag_availability_replicas AS AR2 ON AG.group_id = AR2.group_id INNER JOIN #tmpag_availability_replica_states AS arstates2 ON AR2.replica_id = arstates2.replica_id AND arstates2.is_local = 1 WHERE (AG.name='App1On') drop table #tmpag_availability_groups drop table #tmpag_availability_group_states drop table #tmpag_availability_replicas drop table #tmpag_availability_replica_states
得出如下报错：
消息 207，级别 16，状态 1，第 10 行
列名 'required_copies_to_commit' 无效。
语句中
用到的是
master.sys.availability_groups
中required_copies_to_commit列，而实际上该系统视图根本没有该列，只有required_synchronized_secondaries_to_commit列。
查了下网上有同样的问题：

当前运行的SQL Server 2017没有来得及更新SQLPS。
尝试打补丁
从https://support.microsoft.com/en-us/help/4047329下载最新的累积补丁CU6，安装SQLServer2017-KB4101464-x64.exe。实际并没有对SQLPS模块进行更新。该问题依然存在。
“
There are two SQL Server PowerShell modules; SqlServer and SQLPS. The SQLPS module is included with the SQL Server installation (for backwards compatibility), but is no longer being updated. The most up-to-date PowerShell module is the SqlServer module. The SqlServer module contains updated versions of the cmdlets in SQLPS, and also includes new cmdlets to support the latest SQL features.
Previous versions of the SqlServer module were included with SQL Server Management Studio (SSMS), but only with the 16.x versions of SSMS. To use PowerShell with SSMS 17.0 and later, the SqlServer module must be installed from the PowerShell Gallery. To install the SqlServer module, see Install SQL Server PowerShell.

尝试安装SqlServer模块
先下载保存模块：
Save-Module -Name SqlServer -Path C:\powershellgallery
将下载的SqlServer模块文件夹拷贝到%ProgramFiles%/WindowsPowershell/Module/下。
加载即用、用时注册：
Import-Module -Name SqlServer
使用新的SqlServer模块后，没有遇到问题了。
