条件GROUP BY结果

Question

我需要查询按name进行分组，如果is_new的一个为1，则结果值应为1

---

当前行：

+--------+--------+
| name   | is_new |
+--------+--------+
| a      |      0 |
| a      |      0 |
+--------+--------+
| b      |      0 |
| b      |      1 |
+--------+--------+
| c      |      1 |
| c      |      1 |
+--------+--------+

预期查询结果：

+--------+--------+
| name   | is_new |
+--------+--------+
| a      |      0 |
| b      |      1 |
| c      |      1 |
+--------+--------+
