explain select code from test1 order by name desc;结果: 这里建立的是code和name的联合索引,顺序是code在前,name在后,这里直接按name降序,跟之前联合索引的顺序不一样。 Using index表示是否用了覆盖索引,说白了它表示是否所有获取的列都走了索引。 上面那个例子中其实就用到了:Using index,因为只返回一列code...
D:using filesort:排序时无法使用到索引时,就会出现这个。常见于order by和group by语句中。 E:using index:查询时不需要回表查询,直接通过索引就可以获取查询的数据。 F:using join buffer(block nested loop),using join buffer(batched key accss):5.6.x之后的版本优化关联查询的BNL,BKA特性。主要是减少内表...
select 查询的序列号,表示查询中执行 select 子句或者操作表的顺序(id相同,执行顺序从上到下;id不同,值越大越先执行),单表查询,只有一条记录,多表查询会有多条记录。 select_type 表示SELECT 的类型,常见取值有 SIMPLE(简单表,即不适用表连接或者子查询)、PRIMARY(主查询,即外层的查询)、UNION(UNION中的第二...

The dotted line shows the best fit, and as such, data points above this line increased by more than the overall trend, and those below it by less. Data items whose value was blank in either period won't appear on the scatter plot (for example, Home Appliances in this case). The 100...
