这个例子是把data中2条数据的【role、rank】字段都更新为【"primaryschoolstudent"、5】吗?@caibirdme

【a,b】作为唯一索引的前提下,INSERT INTO table (a,b,c) VALUES (1,2,3),(4,5,6) ON DUPLICATE KEY UPDATE c=VALUES(c);的功能是:

执行该sql前,假设数据如下:
| a | b | c |
| 1 | 2 | -1 |
| 4 | 5 | -1 |

执行该sql后,预期结果如下:
| a | b | c |
| 1 | 2 | 3 |
| 4 | 5 | 6 |

即该语句会将不同行的【c】更新为不同的值。
