mysql - 带日期的 SQL Count (*) 函数

Question

如何在设定的日期参数中使用计数 (*) 函数？我有一个订单记录表，我只想计算特定日期的订单记录。

我的查询是

SELECT COUNT (*) 
FROM bets
WHERE order_date='2018-01-22';

然后返回了这个

1 queries executed, 0 success, 1 errors, 0 warnings

cQuery: SELECT COUNT (*) FROM bets WHERE order_date='2018-01-22' LIMIT 0, 1000

Error Code: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '*) FROM bets WHERE order_date='2018-01-22' LIMIT 0, 1000' at line 1
