The case:
我有一个表(300行)房地产这些细节:
id | locality| postcode| declat | declong | alias |
---------------------------------------------------------------------
13 | | | | | bla bla wimar bla |
14 | | | | | bla bla bla bla |
15 | | | | | bla bla bla arafo |
和其他包含此数据的邮政编码表(900行):
locality| postcode | lat | long
---------------------------------------------
cande | 504 | 37.9418594 | -0.7795244
arafo | 501 | 38.9418594 | -0.7795255
wimar | 500 | 39.9418594 | -0.7795277
我需要像这样更新表格的行:
id | locality| postcode| declat | declong | alias |
---------------------------------------------------------------------------
13 | wimar | 500 | 39.9418594 |-0.7795277 | bla bla wimar bla |
14 | | | | | bla bla bla bla |
15 | arafo | 501 | 38.9418594 |-0.7795255 | bla bla bla arafo |
谢谢。
答案 0 :(得分:0)
根据您的rdbms,如果这只是一次性的,您可以尝试这样的事情:
UPDATE realty
SET locality = p.locality
,postcode = p.postcode
,declat = p.declat
,declong = p.declong
FROM postcodes p
WHERE alias LIKE '%' || p.locality || '%'
要注意的一堆东西(扫描,重复匹配等)
