SQL ELSE 取当前值

Question

如果不符合上述条件，你能帮我写一下ELSE语句吗？我只想让它接受当前值。

CASE
WHEN (Country IS NULL AND (NAME like '%+US+%' OR NAME like '%US-%')) THEN "US"  
WHEN (Country IS NULL AND (NAME like '%+CA+%' OR NAME like '%CA-%')) THEN "CA"  
ELSE **take whatever it is in the Country column**
END AS Country,

Answer 1

对于“无论有什么”部分，请尝试

其他国家/地区

Answer 2

只需使用 ELSE COUNTRY 而不是 ELSE **take whatever it is in the Country column** END AS Country,
