来自select的postgresql更新列

Question

我正在尝试使用select查询更新一个表的列。

它运行并更新整个type_列为religious（文本字段）。

我想只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

我想这是你想要什么：

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