sql - postgresql 更新列从选择

Question

我正在尝试使用选择查询更新一个表中的列。

它运行并将整个 type_ 列更新为 religious(文本字段)。

我试图只更新宗教几何图形与宗地几何图形相交的行。

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);
