錯誤拋出的子查詢返回超過1行

Question

子查詢返回超過1行，在concat操作語法錯了，我能不能識別語法錯誤

select case when a.log_type='Schedule'

        a.log_date BETWEEN CURDATE()-INTERVAL 1 WEEK AND CURDATE() order by a.log_gid desc ; 

Answer 1

這裏有一個明顯的語法錯誤：

a.log_date BETWEEN CURDATE() - INTERVAL 1 WEEK AND CURDATE() 

你試圖用where子句的那部分來做什麼？
