select中的postgresql更新列

Question

我正在尝试使用select查询从一个表更新列。

它会将整个type_列作为religious（文本字段）运行并更新。

我试图仅更新宗教几何与宗地几何相交的行。

update wash_parcels_final
set    type_ = t.religious 
from   (select wash_worship.religious 
        from   wash_parcels_final 
        join   wash_worship 
        on     st_intersects(wash_worship.geom, wash_parcels_final.geom)) t

Answer 1

我认为这就是你想要的：

update wash_parcels_final
    set type_ = ww.religious 
    from wash_worship ww  
    where st_intersects(ww.geom, wash_parcels_final.geom);
