    什么是索引下推?

    索引下推 直接用官方的例子说明:有一个索引 INDEX (zipcode, lastname, firstname) 有一个查询如下: SELECT * FROM people WHERE zipcode lastname LIKE '%etrunia%' AND address LIKE '%Main Street%'; 本来是不能命中全部索引的,因为后面两个条件是左 % LIKE,当然最左匹配原则可以先利用 zipcode MySQL can use the index to scan through people with zipcode='95054'. without Index Condition Pushdown, this query must retrieve full table rows for all people who have zipcode This avoids reading full rows corresponding to index tuples that match the zipcode condition but not
