SQL语句错误：`LEFT ON` 和 `WHERE` 用法解析及修正

"SELECT o.*,a.province_name ,a.city_name, a.district_name ,a.detail ,FROM orders AS o LEFT ON address_book AS a WHERE o.address_book_id=2; 这个SQL语句哪里有问题 应怎么改正" 这个SQL语句有两个问题：\n\n1. LEFT ON应该改为LEFT JOIN，用于指定连接的表和连接条件。\n\n2. 在LEFT JOIN语句后面，应该使用ON关键字指定连接条件，而不是使用WHERE关键字。\n\n下面是改正后的SQL语句：\n\nsql\nSELECT o.*, a.province_name, a.city_name, a.district_name, a.detail \nFROM `orders` AS o \nLEFT JOIN `address_book` AS a ON o.address_book_id = a.address_book_id \nWHERE o.address_book_id = 2;\n
