爲什麼獅身人面像不返回屬性名稱？

Question

我搜索使用兩個指標在獅身人面像：

#users 
source users : lsParentSource 
{ 

    sql_query_range = SELECT MIN(idDetailToUsers), MAX(idDetailToUsers) FROM detailtousers 
    sql_query   = SELECT idDetailToUsers as id, 1000 as type, UsersTypeAccount, idDetailToUsers, SpecializationName, DetailToUsersName, DetailToUsersPhoto, city, country FROM detailtousers join users ON users.idUsers = detailtousers.idDetailToUsers left join usersspecialization ON usersspecialization.UsersSpecializationIdUser = detailtousers.idDetailToUsers left join specializationtousers ON specializationtousers.idSpecialization = usersspecialization.UsersSpecializationIdSpecialization WHERE idDetailToUsers >= $start AND idDetailToUsers <= $end GROUP BY idDetailToUsers 

    sql_attr_uint  = type 
    sql_attr_uint  = idDetailToUsers 
    sql_attr_uint  = UsersTypeAccount 
    sql_field_string = SpecializationName 
    sql_field_string = DetailToUsersName 
    sql_field_string = DetailToUsersPhoto 
    sql_attr_uint  = city 
    sql_attr_uint  = country 

    sql_query_info = SELECT idDetailToUsers, DetailToUsersName, UsersTypeAccount, SpecializationName, DetailToUsersPhoto, city, country \ 
         FROM detailtousers WHERE idDetailToUsers = $id 
    sql_ranged_throttle = 0 
} 


#medical 
source medical : lsParentSource 
{ 

    sql_query_range = SELECT MIN(idMedicalFacilities), MAX(idMedicalFacilities) FROM medicalfacilities 
    sql_query   = SELECT idMedicalFacilities as id, 2000 as type, idMedicalFacilities, MedicalFacilitiesName, MedicalFacilitiesPhoto, city, country FROM medicalfacilities WHERE idMedicalFacilities >= $start AND idMedicalFacilities <= $end 

    sql_attr_uint  = type 
    sql_attr_uint  = MedicalFacilitiesIdUser 
    sql_attr_uint  = idMedicalFacilities 
    sql_field_string = MedicalFacilitiesName 
    sql_field_string = MedicalFacilitiesPhoto 
    sql_attr_uint  = city 
    sql_attr_uint  = country 

    sql_query_info = SELECT MedicalFacilitiesIdUser, MedicalFacilitiesName, MedicalFacilitiesPhoto FROM medicalfacilities WHERE idMedicalFacilities = $id 
    sql_ranged_throttle = 0 
} 

如果使用索引users只有它返回我的選擇查詢指定的所有屬性。 但是，如果使用兩個索引，獅身人面像不返回屬性。 什麼是原因？

結果爲指數users：

array(1) { 
    [533]=> 
    array(2) { 
    ["weight"]=> 
    int(1) 
    ["attrs"]=> 
    array(0) { 
    } 
    } 
} 

結果爲指數medical：

array(5) { 
    [451]=> 
    array(2) { 
    ["weight"]=> 
    int(2) 
    ["attrs"]=> 
    array(0) { 
    } 
    } 
    [444]=> 
    array(2) { 
    ["weight"]=> 
    int(1) 
    ["attrs"]=> 
    array(0) { 
    } 
    }

獅身人面像只返回屬性共同在查詢索引。你有不同的名字。

您可能能夠在SetSelect中使用sphinxQL中的EXISTS函數，但從未嘗試過。

最簡單的就是使用相同的屬性名稱。
