假设我们要创建合并复制的发布端数据库是EFDemo其中有四张表,订阅端数据库是EFDemoSubscription,如下图所示:
首先创建发布端快照代理Sql agent job:"EFDemoMergePublicationJob":
USE [msdb] GO /****** Object: Job [EFDemoMergePublicationJob] Script Date: 11/29/2018 12:59:12 PM ******/ BEGIN TRANSACTION DECLARE @ReturnCode INT SELECT @ReturnCode = 0 /****** Object: JobCategory [REPL-Snapshot] Script Date: 11/29/2018 12:59:12 PM ******/ IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'REPL-Snapshot' AND category_class=1) BEGIN EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'REPL-Snapshot' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback END DECLARE @jobId BINARY(16) EXEC @ReturnCode = msdb.dbo.sp_add_job @job_name=N'EFDemoMergePublicationJob', @enabled=1, @notify_level_eventlog=0, @notify_level_email=0, @notify_level_netsend=0, @notify_level_page=0, @delete_level=0, @description=N'No description available.', @category_name=N'REPL-Snapshot', @owner_login_name=N'domainscott', @job_id = @jobId OUTPUT IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Snapshot Agent startup message.] Script Date: 11/29/2018 12:59:12 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Snapshot Agent startup message.', @step_id=1, @cmdexec_success_code=0, @on_success_action=3, @on_success_step_id=0, @on_fail_action=3, @on_fail_step_id=0, @retry_attempts=0, @retry_interval=0, @os_run_priority=0, @subsystem=N'TSQL', @command=N'sp_MSadd_snapshot_history @perfmon_increment = 0, @agent_id = 4, @runstatus = 1, @comments = N''Starting agent.''', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Run agent.] Script Date: 11/29/2018 12:59:12 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Run agent.', @step_id=2, @cmdexec_success_code=0, @on_success_action=1, @on_success_step_id=0, @on_fail_action=3, @on_fail_step_id=0, @retry_attempts=10, @retry_interval=1, @os_run_priority=0, @subsystem=N'Snapshot', @command=N'-Publisher [DB_Server_001] -PublisherDB [EFDemo] -Distributor [DB_Server_001] -Publication [EFDemoMerge] -ReplicationType 2 -DistributorSecurityMode 1 ', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Detect nonlogged agent shutdown.] Script Date: 11/29/2018 12:59:12 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Detect nonlogged agent shutdown.', @step_id=3, @cmdexec_success_code=0, @on_success_action=2, @on_success_step_id=0, @on_fail_action=2, @on_fail_step_id=0, @retry_attempts=0, @retry_interval=0, @os_run_priority=0, @subsystem=N'TSQL', @command=N'sp_MSdetect_nonlogged_shutdown @subsystem = ''Snapshot'', @agent_id = 4', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_update_job @job_id = @jobId, @start_step_id = 1 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_add_jobschedule @job_id=@jobId, @name=N'Replication agent schedule.', @enabled=1, @freq_type=4, @freq_interval=14, @freq_subday_type=1, @freq_subday_interval=5, @freq_relative_interval=1, @freq_recurrence_factor=0, @active_start_date=20181129, @active_end_date=99991231, @active_start_time=500, @active_end_time=235959, @schedule_uid=N'561c3b92-52c3-4661-b3c3-916807f2db2a' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback COMMIT TRANSACTION GOTO EndSave QuitWithRollback: IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION EndSave: GO
然后创建订阅端数据同步Sql agent job:"EFDemoMergeSubscriptionJob":
USE [msdb] GO /****** Object: Job [EFDemoMergeSubscriptionJob] Script Date: 11/29/2018 12:57:11 PM ******/ BEGIN TRANSACTION DECLARE @ReturnCode INT SELECT @ReturnCode = 0 /****** Object: JobCategory [REPL-Merge] Script Date: 11/29/2018 12:57:11 PM ******/ IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'REPL-Merge' AND category_class=1) BEGIN EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'REPL-Merge' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback END DECLARE @jobId BINARY(16) EXEC @ReturnCode = msdb.dbo.sp_add_job @job_name=N'EFDemoMergeSubscriptionJob', @enabled=1, @notify_level_eventlog=2, @notify_level_email=0, @notify_level_netsend=0, @notify_level_page=0, @delete_level=0, @description=N'No description available.', @category_name=N'REPL-Merge', @owner_login_name=N'domainscott', @job_id = @jobId OUTPUT IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Merge Agent startup message.] Script Date: 11/29/2018 12:57:11 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Merge Agent startup message.', @step_id=1, @cmdexec_success_code=0, @on_success_action=3, @on_success_step_id=0, @on_fail_action=3, @on_fail_step_id=0, @retry_attempts=0, @retry_interval=0, @os_run_priority=0, @subsystem=N'TSQL', @command=N'sp_MSadd_merge_history @perfmon_increment = 0, @agent_id = 4, @runstatus = 1, @comments = N''Starting agent.''', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Run agent.] Script Date: 11/29/2018 12:57:11 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Run agent.', @step_id=2, @cmdexec_success_code=0, @on_success_action=1, @on_success_step_id=0, @on_fail_action=3, @on_fail_step_id=0, @retry_attempts=10, @retry_interval=1, @os_run_priority=0, @subsystem=N'Merge', @command=N'-Publisher [DB_Server_001] -PublisherDB [EFDemo] -Publication [EFDemoMerge] -Subscriber [DB_Server_001] -SubscriberDB [EFDemoSubscription] -Distributor [DB_Server_001] -DistributorSecurityMode 1 ', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback /****** Object: Step [Detect nonlogged agent shutdown.] Script Date: 11/29/2018 12:57:11 PM ******/ EXEC @ReturnCode = msdb.dbo.sp_add_jobstep @job_id=@jobId, @step_name=N'Detect nonlogged agent shutdown.', @step_id=3, @cmdexec_success_code=0, @on_success_action=2, @on_success_step_id=0, @on_fail_action=2, @on_fail_step_id=0, @retry_attempts=0, @retry_interval=0, @os_run_priority=0, @subsystem=N'TSQL', @command=N'sp_MSdetect_nonlogged_shutdown @subsystem = ''Merge'', @agent_id = 4', @server=N'DB_Server_001', @database_name=N'distribution', @flags=0 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_update_job @job_id = @jobId, @start_step_id = 1 IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_add_jobschedule @job_id=@jobId, @name=N'Replication agent schedule.', @enabled=0, @freq_type=1, @freq_interval=0, @freq_subday_type=0, @freq_subday_interval=0, @freq_relative_interval=0, @freq_recurrence_factor=0, @active_start_date=20181129, @active_end_date=99991231, @active_start_time=0, @active_end_time=235959, @schedule_uid=N'ad0c8cc4-c11e-4b9e-8f23-234f37e29925' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback EXEC @ReturnCode = msdb.dbo.sp_add_jobserver @job_id = @jobId, @server_name = N'(local)' IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback COMMIT TRANSACTION GOTO EndSave QuitWithRollback: IF (@@TRANCOUNT > 0) ROLLBACK TRANSACTION EndSave: GO
然后就可以开始创建合并复制了:

@active_start_date = 0, @active_end_date = 0 GO
这样我们就用SQL脚本创建了合并复制的发布端和订阅端。
也可以用下面的SQL脚本来删除合并复制的发布端和订阅端。
-- 用sp_dropmergesubscription,先删除合并复制的所有订阅端,注意这个存储过程并不会清除每个订阅端数据库中的合并复制对象(合并复制自动创建的系统表、触发器、约束、表中的RowGuid列等) use [EFDemo] exec sp_dropmergesubscription @publication = N'EFDemoMerge', @subscriber = N'DB_Server_001', @subscriber_db = N'EFDemoSubscription' GO -- 用sp_dropmergearticle,删除合并复制中发布端所有Article(发布端数据库中复制的所有表、存储过程等对象) use [EFDemo] exec sp_dropmergearticle @publication = N'EFDemoMerge', @article = N'Book', @force_invalidate_snapshot = 1, @force_reinit_subscription = 1 GO use [EFDemo] exec sp_dropmergearticle @publication = N'EFDemoMerge', @article = N'Cars', @force_invalidate_snapshot = 1, @force_reinit_subscription = 1 GO use [EFDemo] exec sp_dropmergearticle @publication = N'EFDemoMerge', @article = N'House', @force_invalidate_snapshot = 1, @force_reinit_subscription = 1 GO use [EFDemo] exec sp_dropmergearticle @publication = N'EFDemoMerge', @article = N'Person', @force_invalidate_snapshot = 1, @force_reinit_subscription = 1 GO use [EFDemo] exec sp_dropmergearticle @publication = N'EFDemoMerge', @article = N'Product', @force_invalidate_snapshot = 1, @force_reinit_subscription = 1 GO -- 再用sp_dropmergepublication,删除合并复制的发布端,要先调用sp_dropmergesubscription将合并复制的订阅端删除完后,才能成功调用这个存储过程,否则会报错 use [EFDemo] exec sp_dropmergepublication @publication = N'EFDemoMerge' GO -- 最后记得用sp_removedbreplication,来清除每个订阅端数据库中的合并复制对象(合并复制自动创建的系统表、触发器、约束、表中的RowGuid列等) -- 很奇怪不知道为啥上面的sp_dropmergesubscription不会删除订阅端数据库中的合并复制对象 USE master EXEC sp_removedbreplication @dbname='EFDemoSubscription' GO
当然上面这些脚本也可以在SQL Server Management Studio中自动生成出来,不用自己去写。
使用SQL脚本创建带分区的合并复制
带分区的合并复制只能用存储过程来创建,首先通过如下存储过程,用发布端数据库EFDemo来创建合并复制EFDemoMerge:
-- 添加合并复制功能(合并复制自动创建的系统表)到发布端数据库EFDemo use master exec sp_replicationdboption @dbname = N'EFDemo', @optname = N'merge publish', @value = N'true' GO -- 添加合并复制EFDemoMerge,即发布端 use [EFDemo] exec sp_addmergepublication @publication = N'EFDemoMerge', @description = N'Merge publication of database ''EFDemo'' from Publisher ''DB_Server_001''.', @sync_mode = N'native', @retention = 14, @allow_push = N'true', @allow_pull = N'true', @allow_anonymous = N'true', @enabled_for_internet = N'false', @snapshot_in_defaultfolder = N'true', @compress_snapshot = N'false', @ftp_port = 21, @ftp_subdirectory = N'ftp', @ftp_login = N'anonymous', @allow_subscription_copy = N'false', @add_to_active_directory = N'false', @dynamic_filters = N'true', @conflict_retention = 14, @keep_partition_changes = N'true', @allow_synctoalternate = N'false', @max_concurrent_merge = 0, @max_concurrent_dynamic_snapshots = 0, @use_partition_groups = N'true', @publication_compatibility_level = N'100RTM', @replicate_ddl = 1, @allow_subscriber_initiated_snapshot = N'false', @allow_web_synchronization = N'false', @allow_partition_realignment = N'true', @retention_period_unit = N'days', @conflict_logging = N'both', @automatic_reinitialization_policy = 0 GO
其中有四个参数黄色高亮标记了出来是开启分区合并复制的关键:
- @dynamic_filters = N'true' 分区合并复制必须使用动态函数(HOST_NAME()就是动态函数),所以要开启动态筛选
- @keep_partition_changes = N'true'
- @use_partition_groups = N'true'
- @allow_partition_realignment = N'true'
然后将发布端快照代理Sql agent job:"EFDemoMergePublicationJob"分配给合并复制的发布端,这个没什么特别的:
-- 将前面创建的发布端快照代理Sql agent job:"EFDemoMergePublicationJob"分配给合并复制的发布端 -- 注意@publisher_login , @publisher_password 两个参数是发布端数据库的管理员用户名和密码 exec sp_addpublication_snapshot @snapshot_job_name=N'EFDemoMergePublicationJob', @publication = N'EFDemoMerge', @frequency_type = 4, @frequency_interval = 14, @frequency_relative_interval = 1, @frequency_recurrence_factor = 0, @frequency_subday = 1, @frequency_subday_interval = 5, @active_start_time_of_day = 500, @active_end_time_of_day = 235959, @active_start_date = 0, @active_end_date = 0, @job_login = null, @job_password = null, @publisher_security_mode = 0, @publisher_login = N'Distribution', @publisher_password = N'1qaz!QAZ' exec sp_grant_publication_access @publication = N'EFDemoMerge', @login = N'sa' GO
然后在添加合并复制的Article时,至少要有一个Article对象使用了带动态函数的Filter,下面的MD.Cars表上就使用了HOST_NAME()动态函数来作为Filter:
-- 添加合并复制EFDemoMerge的Article(选取数据库EFDemo中要复制的表、存储过程等,当运行发布端快照代理Sql agent job:"EFDemoMergePublicationJob"后,合并复制会在下面选取的表中创建触发器、约束、RowGuid列等) use [EFDemo] exec sp_addmergearticle @publication = N'EFDemoMerge', @article = N'Book', @source_owner = N'dbo', @source_object = N'Book', @type = N'table', @description = N'', @creation_script = N'', @pre_creation_cmd = N'drop', @schema_option = 0x000000010C034FD1, @identityrangemanagementoption = N'auto', @pub_identity_range = 10000, @identity_range = 1000, @threshold = 80, @destination_owner = N'dbo', @force_reinit_subscription = 1, @column_tracking = N'false', @subset_filterclause = N'', @vertical_partition = N'false', @verify_resolver_signature = 1, @allow_interactive_resolver = N'false', @fast_multicol_updateproc = N'true', @check_permissions = 0, @subscriber_upload_options = 0, @delete_tracking = N'true', @compensate_for_errors = N'false', @stream_blob_columns = N'true', @partition_options = 3 GO use [EFDemo] exec sp_addmergearticle @publication = N'EFDemoMerge', @article = N'Cars', @source_owner = N'MD', @source_object = N'Cars', @type = N'table', @description = N'', @creation_script = N'', @pre_creation_cmd = N'drop', @schema_option = 0x000000010C034FD1, @identityrangemanagementoption = N'auto', @pub_identity_range = 10000, @identity_range = 1000, @threshold = 80, @destination_owner = N'MD', @force_reinit_subscription = 1, @column_tracking = N'false', @subset_filterclause = N'[CarName] =HOST_NAME()', @vertical_partition = N'false', @verify_resolver_signature = 1, @allow_interactive_resolver = N'false', @fast_multicol_updateproc = N'true', @check_permissions = 0, @subscriber_upload_options = 0, @delete_tracking = N'true', @compensate_for_errors = N'false', @stream_blob_columns = N'true', @partition_options = 3 GO
可以看到上面我们添加了两张表dbo.Book和MD.Cars作为合并复制的Article,黄色高亮标记处显示,我们在MD.Cars表上使用了[CarName] =HOST_NAME()来作为Filter,其中使用了动态函数HOST_NAME()
最后运行发布端快照代理Sql agent job:"EFDemoMergePublicationJob",然后我们可以看到在合并复制EFDemoMerge的属性中多了个选项叫"Data Partitions":
可以在这里添加分区,每个分区的HOST_NAME是分区的唯一标识符,也是动态函数HOST_NAME()的返回值:
当然分区还可以通过存储过程sp_addmergepartition来添加。
这里再附上几个关于分区合并复制的链接:
