[Err] 1071 - Specified key was too long; max key length is 767 bytes

[Err] 1071 - Specified key was too long; max key length is 767 bytes 是一个错误信息，表明创建索引时指定的键太长，超过了最大长度限制为767字节。这个错误通常与MySQL数据库的限制有关。MySQL的innodb存储引擎对于单个列的长度限制为767字节，对于多列索引的长度限制为3072字节。这意味着每个列的长度不能大于767字节，而组成索引的所有列的长度总和不能超过3072字节。因此，如果在创建索引时指定的键长度超过了这些限制，就会出现这个错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
