每個記錄顯示信息,我有這個表:在二郎
-record(person, {id, firstname, lastname}).
,它包含此值:
13 asma chabani
14 nawel jirard
15 ahme bahri
我要顯示的每個記錄的名字和姓氏:
我嘗試:
test()->
Match=#person{_ = '_'}, %Will match all records
Fun =
fun() ->
List = mnesia:match_object(Match),
lists:foreach(fun(X) ->
M=X#person.fistname,
H=X#person.lastname,
io:format("~s~n",[M]),
io:format("~s~n",[H])
end,
List)
end.
但它顯示此錯誤:
model:test().
#Fun<model.186.53419390>
'#Fun' - 這不是錯誤,這是你定義的函數'Fun = fun()...' –
