教义集案例何时

Question

是否可以在Doctrine中编写以下SQL查询？

UPDATE Inventory 
SET 
 a = CASE WHEN a=id THEN NULL ELSE a END,
 b = CASE WHEN b=id THEN NULL ELSE b END,
 c = CASE WHEN c=id THEN NULL ELSE c END,
 d = CASE WHEN d=id THEN NULL ELSE d END,
 e = CASE WHEN e=id THEN NULL ELSE e END,
 f = CASE WHEN f=id THEN NULL ELSE f END,
 g = CASE WHEN g=id THEN NULL ELSE g END,
 h = CASE WHEN h=id THEN NULL ELSE h END,
 i = CASE WHEN i=id THEN NULL ELSE i END,
 j = CASE WHEN j=id THEN NULL ELSE j END,
 k = CASE WHEN k=id THEN NULL ELSE k END
WHERE userid=uid;

Answer 1

不，Doctrine不支持CASE WHEN语句 - 你可以尝试使用RAW SQL ....
