更新加入 postgresql - 關系不存在

Question

我將 DBeaver 用作 DBMS，並嘗試根據連接更新表：

update cbn
set cbn.pathways = pc.pathways
from public.conformed_block_names cbn
left join pathwayslist_csv pc
    on pc.block_code = cbn.block_code
where pc.block_code is not null 

所以我要做的是根據此表和表 pathwayslist_csv 之間的連接更新表 conformed_block_names

但是，我不斷收到錯誤消息“錯誤：關系“cbn”不存在”

我嘗試過以多種不同方式重構更新，但我沒有取得任何進展

Answer 1

這應該有效：

UPDATE conformed_block_names
SET pathways = pc.pathways
FROM pathwayslist_csv pc
WHERE pc.block_code = conformed_block_names.block_code
    AND pc.block_code IS NOT null;
