该错误告诉您该标识符太长:
这是标识符的最大大小(来自这里:
+----------------------------------+-------------------------------------+
| Identifier | Maximum Length (characters) |
+----------------------------------+-------------------------------------+
| Database | 64 |
| Table | 64 |
| Column | 64 |
| Index | 64 |
| Constraint | 64 |
| Stored Procedure or Function | 64 |
| Trigger | 64 |
| View | 64 |
| Event | 64 |
| Tablespace | 64 |
| Server | 64 |
| Log File Group | 64 |
| Alias | 256 (see exception following table) |
| Compound Statement Label | 16 |
+----------------------------------+-------------------------------------+
该标识符有 65 个字符。
我不确定这在 magento 中意味着什么,但是将其作为标识符看起来很奇怪。
