嗯，你只需要 or 子句所关注的元素在括号.

Well, you just need the elements concerned by the or clause to be between parenthesis.

顺便说一下，它们不是需要的"(您可以使用 AND/OR 的优先顺序)，但我会说这是提高可读性的***方式.

They are not "needed", by the way (you could use precedence order of AND / OR), but I would say this is the best way for readability.

如果 status_id 数据类型为 int，则不需要 ' ' 1 和 2 左右.

And if status_id data type is int, you don't need the ' ' around 1, and 2.

SELECT * 
 FROM tablename 
WHERE name='Ankit' 
AND date='2015-04-23' 
AND (status_id=1 OR status_id=2) 

顺便说一句，在这种情况下，您可以使用 IN 子句

By the way, in this case, you may use an IN clause

AND status_id in (1, 2)
