合併兩個不同的SQL查詢到單個查詢

Question

我有兩個SQL查詢

SELECT sub_id, 
     sub_sent_code, 
     date_time 
FROM moviedatabase.reg_sub_master 
WHERE (date_time >= '2013-01-19' 
     AND date_time <= '2013-01-29'); 

和

SELECT sub_id, 
     sub_sent_code, 
     date_time 
FROM moviedatabase.reg_sub_master 
WHERE date_time <= '2013-01-19'; 

我需求量的是從1號查詢什麼都結果來的是sub_id,sub_sent_code,date_time不應該出現在第二查詢。

我想讓它成爲單個查詢。

編輯：其實我想去的地方date_time >='2013-01-19'和date_time <='2013-01-29'和sub_id這我得到'2013-01-19'

Answer 1

嘗試之前不應該在那裏結果：

SELECT sub_id,sub_sent_code,date_time 
FROM moviedatabase.reg_sub_master 
WHERE (date_time >='2013-01-19' 
    AND date_time <='2013-01-29') 
    AND sub_id NOT IN (
     SELECT DISTINCT sub_id 
     FROM moviedatabase.reg_sub_master 
     WHERE date_time <='2013-01-19;
