Question

为两个Azure SQL数据库（即Staging_Prod和DBSYNC_STAGING_PROD）运行SymmetricDS进行Azure SQL数据库的数据库同步时，我遇到以下错误。

SymmetricDS配置表如下。

insert into sym_node_group (node_group_id) values ('primary-staging_prod-us');
insert into sym_node_group (node_group_id) values ('secondary-staging_prod-us');

insert into sym_node_group_link (source_node_group_id, target_node_group_id, data_event_action) values ('primary-staging_prod-us', 'secondary-staging_prod-us', 'W');
insert into sym_node_group_link (source_node_group_id, target_node_group_id, data_event_action) values ('secondary-staging_prod-us', 'primary-staging_prod-us', 'P');


insert into sym_trigger 
(trigger_id,source_catalog_name,source_schema_name, source_table_name, channel_id, sync_on_insert, sync_on_update, sync_on_delete, last_update_time,create_time, sync_on_incoming_batch)
values('TriggerAll', null, 'dbo', '*', 'matter', 1 , 1, 1, GetDate(), GetDate(), 1);


insert into sym_router 
(router_id,source_node_group_id,target_node_group_id,target_catalog_name,target_schema_name,target_table_name,router_type,create_time,last_update_time)
values('primary_2_secondary-staging_prod-us', 'primary-staging_prod-us', 'secondary-staging_prod-us', null, 'dbo', '*', 'default',GetDate(), GetDate());

insert into sym_router 
(router_id,source_node_group_id,target_node_group_id,target_catalog_name,target_schema_name,target_table_name,router_type,create_time,last_update_time)
values('secondary_2_primary-staging_prod-us', 'secondary-staging_prod-us', 'primary-staging_prod-us', null, 'dbo', '*', 'default', GetDate(), GetDate());


insert into sym_trigger_router (trigger_id,router_id,initial_load_order,last_update_time,create_time)
values('TriggerAll','primary_2_secondary-staging_prod-us', 100, current_timestamp,current_timestamp);
insert into sym_trigger_router (trigger_id,router_id,initial_load_order,last_update_time,create_time)
values('TriggerAll','secondary_2_primary-staging_prod-us', 200, current_timestamp, current_timestamp);

但是，如果我使用正确的目标架构在下面的SQL Server Management Studio中执行alter命令，它将运行正常。

ALTER TABLE "dbo"."AccessMaster"
    ADD CONSTRAINT "FK_AccessMaster_ToFunctions" FOREIGN KEY ("FunctionID") REFERENCES "DBSYNC_STAGING_PROD"."dbo"."Functions" ("id")

SymmetricDS版本==>对称服务器-3.9.14

我认为这个问题即将到来，因为我无法指定目标架构/目录名称。您能否指导我完成新symmetricDS版本中的配置步骤。

问候拉贾特·阿格劳瓦尔（Rajat Agrawal）

Answer 1

问题已解决。看起来好像在2018年10月3日发布的SymmetricDS版本3.9.14中存在一个错误。我刚刚下载了在2018年8月9日发布的稳定版本3.8.40，该错误消失了，我能够在没有任何外键的情况下同步模式更改引用错误。

致谢
