[英]Having difficulty with the WHERE IN clause for MySQL
好的,我意識到這可能非常簡單,但是現在我的大腦已經凍結了。 這個查詢需要一點幫助。 讓我們分解一下。 我有兩個表(每個示例),我想更新一個表的“無法交付”狀態
客戶表 (tbl_customers):
+------------+-------------+
| customerID | custAcctNum |
+------------+-------------+
| 1 | 100100121 |
| 2 | 100100122 |
| 3 | 100100123 |
| 4 | 100100124 |
| 5 | 100100125 |
+------------+-------------+
地址表 (tbl_address):
+-----------+------------+---------------+
| addressID | customerID | undeliverable |
+-----------+------------+---------------+
| 1 | 1 | 0 |
| 2 | 2 | 0 |
| 3 | 3 | 0 |
| 4 | 4 | 0 |
| 5 | 5 | 0 |
+-----------+------------+---------------+
具有“無法交付的”客戶帳號(custAcctNum)的數據集
100100121, 100100123, 100100124
然后查詢會將地址表更新為此
+-----------+------------+---------------+
| addressID | customerID | undeliverable |
+-----------+------------+---------------+
| 1 | 1 | 1 |
| 2 | 2 | 0 |
| 3 | 3 | 1 |
| 4 | 4 | 1 |
| 5 | 5 | 0 |
+-----------+------------+---------------+
這是我嘗試使用的查詢
UPDATE tbl_address
SET undeliverable = 1 WHERE
( SELECT custAcctNum FROM tbl_customers AS c
INNER JOIN tbl_address AS a ON a.customerID = c.customerID )
IN ( 100100121, 100100123, 100100124);
有什么建議么? 謝謝!
UPDATE tbl_address
SET (undeliverable = 1)
WHERE customerID IN (
SELECT customerID
FROM tbl_customers
WHERE custAcctNum IN (100100121, 100100123, 100100124)
);
使用mysql的多表更新語法:
update tbl_Address t
join custAcctNum c
on c.customerid = t.customerid
set t.undeliverable = 1
where c.custAcctNum in (100100121, 100100123, 100100124)
