我試圖刪除它們progresses.behavior.name等於陣列節點「穆爾（1）」我試圖此查詢，但它不會工作。

db.users.update({},{$pull : { "progresses" : { "behavior" : { "name" : "Mur (1)" }}}}); 
db.users.update({}, { $pull : {"progresses.behavior.name" : "Mur (1)"} }, false, true); 

Answer 1

這一個工作：

db.users.update({"progresses.behavior.name" : "Mur (1)"}, { $pull : {"progresses" : { "behavior.name" : "Mur (1)"} } }, false, true);
