不着急执行回表,而是在这条记录上先判断一下所有关于idx_content1索引中包含的条件是否成立,也就是content1 > 'z' AND content1 LIKE '%a'是否成立。如果这些条件不成立,则直接跳过该二级索引记录,去找下一条二级索引记录;如果这些条件成立,则执行回表操作,返回完整的记录给server层。 总结: 未开启索引下推: ...

如果没有索引下推(ICP),那么MySQL在存储引擎层找到满足content1 > 'z'条件的第一条二级索引记录。主键值进行回表,返回完整的记录给server层,server层再判断其他的搜索条件是否成立。如果成立则保留该记录,否则跳过该记录,然后向存储引擎层要下一条记录。
