這裏是選擇Query.Every時候我收到錯誤：未能在Android中使用SQLITE執行簡單的「選擇」查詢？
SELECT
mf.id,
mf.field_type_id,
mf.field_label,
mf.field_values as mf_values,
mf.is_required,
sfv.field_value as sfv_Value
FROM menu_fields mf
LEFT OUTER JOIN site_field_values sfv
ON mf.id=sfv.menu_fields_id
AND sfv.proposal_id=100000 WHERE mf.menu_id=2;
這裏是logcat的：
