[GitHub] [shardingsphere] pedesdestiny opened a new issue, #18458: multiple datasource route table error ?

There is multiple dataNodes. crm_was_0~9 are sub database and sub table, crm_was and main_data are single dataNode. 'default-data-source-name' is configed with 'crm_was', so i config 'main_data' in sharding rules.
problems：
query single table of crm_was is ok. but when i use sub or join to query table of crm_was, then routing to main_data error occurs. like this:
thanks for your answer!!!

Thank you for your remind. Any version can support this way applying table in sharding rules directly？
