在UNION結果中刪除重複結果Mysql

我有一些表，我創建查詢使用UNION將該表連接到一個表。但我有一些問題，結果有重複的值。在UNION結果中刪除重複結果Mysql

這裏是我的UNION的結果：

enter image description here

這裏是我的查詢：

SELECT * FROM (
SELECT d.type, d.is_delete, a.CUSTOMER_ID, a.ANI, a.FULL_NAME, a.ALAMAT, 
a.CITY, a.PROVINCE_DESC, a.ZIP_CODE, a.PSTN, a.MOBILE, a.EMAIL, 
b.location_id, c.INSTALL_ADDR, c.PSTN as UPD_PSTN, c.MOBILE as UPD_MOBILE 
FROM dailybussolbackup.daily_bussol_20150101 a 
LEFT JOIN collectionticket.ticket_location_kcp b ON a.CUSTOMER_ID = b.CUSTOMER_ID 
LEFT JOIN collectionticket.ticket_customers c ON a.CUSTOMER_ID = c.CUSTOMER_ID 
LEFT JOIN ticket_schedule_complaint d ON d.customer_id = a.CUSTOMER_ID 
WHERE b.location_id = '3' 
     UNION 
SELECT d.type, d.is_delete, a.CUSTOMER_ID, a.ANI, a.FULL_NAME, a.ALAMAT, 
a.CITY, a.PROVINCE_DESC, a.ZIP_CODE, a.PSTN, a.MOBILE, a.EMAIL, 
b.location_id, c.INSTALL_ADDR, c.PSTN as UPD_PSTN, c.MOBILE as UPD_MOBILE 
FROM dailybussolbackup.daily_bussol_20150101 a 
LEFT JOIN collectionticket.ticket_location_kcp b ON a.CUSTOMER_ID = b.CUSTOMER_ID 
LEFT JOIN collectionticket.ticket_customers c ON a.CUSTOMER_ID = c.CUSTOMER_ID 
LEFT JOIN ticket_schedule_detail d ON d.cust_id = a.CUSTOMER_ID 
LEFT JOIN ticket_schedule e ON e.id = d.schedule_id 
WHERE b.location_id = '3' 
) as data 
WHERE data.is_delete = 'false' OR data.is_delete IS NULL;

這裏是我的預期結果：

刪除行type和is_delete列有NULL值和重複。如何清理它？謝謝..

重複是指具有相同值的所有列，這就是工會會怎麼看重複。 –

該結果中的所有行都不重複。 –

要澄清其他人在說什麼，請嘗試從您的選擇中移除前兩列，您應該看到假定的重複項消失。 – Giles

似乎其餘的字段就像結果集的「PK」。這將在存在時使用'type'和'is_delete'值，或者在其他情況下爲null。
這是一個有點棘手（可能是內部子查詢更好的查詢分析）
