您可能需要尝试以下方法：
SELECt CONCAt(title, ' ', forename, ' ', surname) AS nameFROM customer cJOIN ( SELECt MAX(id) max_id, customer_id FROM customer_data GROUP BY customer_id ) c_max ON (c_max.customer_id = c.customer_id)JOIN customer_data cd ON (cd.id = c_max.max_id)WHERe CONCAt(title, ' ', forename, ' ', surname) LIKE '%Smith%' LIMIT 10, 20;
请注意，a
JOIN只是的同义词
INNER JOIN。
测试用例：
CREATE TABLE customer (customer_id int);CREATE TABLE customer_data ( id int, customer_id int, title varchar(10), forename varchar(10), surname varchar(10));INSERT INTO customer VALUES (1);INSERT INTO customer VALUES (2);INSERT INTO customer VALUES (3);INSERT INTO customer_data VALUES (1, 1, 'Mr', 'Bobby', 'Smith');INSERT INTO customer_data VALUES (2, 1, 'Mr', 'Bob', 'Smith');INSERT INTO customer_data VALUES (3, 2, 'Mr', 'Jane', 'Green');INSERT INTO customer_data VALUES (4, 2, 'Miss', 'Jane', 'Green');INSERT INTO customer_data VALUES (5, 3, 'Dr', 'Jack', 'Black');
结果（不含
LIMIT和的查询
WHERe）：
SELECt CONCAt(title, ' ', forename, ' ', surname) AS nameFROM customer cJOIN ( SELECt MAX(id) max_id, customer_id FROM customer_data GROUP BY customer_id ) c_max ON (c_max.customer_id = c.customer_id)JOIN customer_data cd ON (cd.id = c_max.max_id);+-----------------+| name |+-----------------+| Mr Bob Smith || Miss Jane Green || Dr Jack Black |+-----------------+3 rows in set (0.00 sec)
