SQL：將編碼行存儲爲給定ID的單獨列

Question

我有一個包含一組地址的地理編碼數據的表。問題在於經度和緯度存儲在同一列中，但在同一個表中的另一列中通過代碼（0或1）進行區分。每個地址都標有一個在列中出現兩次的唯一ID（1表示拉特，1表示長）。

我想在同一行顯示緯度和長度作爲單獨的列以及相應的ID。

Answer 1

select unique_id, 
     max(case when code = 0 then geocoded_column end) as lat, 
     max(case when code = 1 then geocoded_column end) as long 
    from geocoded_table 
    group by unique_id 

Answer 2

with ttt as (
      select 111 ID, '54.65548' coords, 1 def from dual 
      union all 
      select 111 ID, '-34.8456' coords, 0 def from dual 
      ) 
select t1.ID, t1.coords, t2.coords 
from ttt t1 
    join ttt t2 ON t1.ID = t2.ID 
        and t1.def <> t2.def 
        and t1.def = 1 -- or t1.def = 0 if you want change order of coords
