复杂SQL的子查询中的多表关联，执行计划中表连接顺序不一样，导致sql执行效率降低。
案例1：
问题背景：测试环境同一个SQL执行比生产的快，测试环境的数据库是上周覆盖过的。数据量大致相同，表结构相同。
生产IP：10.18.xxx mariadb 10.1.18
测试IP：10.16.xxx mariadb 10.1.11
数据库是： midea_gls
具体SQL如下所示：
select * from ( select goy.is_replacement_order, goy.ycon_no,go.booking_req_no,go.export_org_name,go.salesman_name,go.shipping_personnel_name,gtyr.warehouse_name,gsn.delivery_order_number,go.status,gtyr.ycon_status from go_order_ycon goy left join go_order go on go.order_no = goy.order_no left join go_task_ycon_refrence gtyr on gtyr.ycon_no = goy.ycon_no and gtyr.order_no =goy.order_no left join go_shipment_notice gsn on gsn.vir_container_number = gtyr.ycon_no where (goy.ycon_no ='VCH201808280034' or goy.lcl_vir_container_number = 'VCH201808280034' or goy.ycon_no in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034') or goy.lcl_vir_container_number in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034')) ) TEMP where TEMP.ycon_status <>'Y_110' AND TEMP.status = 'O_10'\G
关联查询的四个表如下所示，表结构和索引在两套数据库上一致。

疑问： 为何相同的表结构，大致相同的数据量和数据分布。SQL执行计划不一样，性能差别太大。
问题处理：
首先发对比两个库的数据库版本信息、sql_mode 设置、optimizer_switch 配置信息、表结构、表字段字符集、表字段校验集信息、表索引信息、表数据数量。发现以上配置都是一致的。
这令人比较难以理解，mysql 到底是如何对复杂SQL进行优化执行的。这个需要后面查阅资料进行测试研究。
临时处理方案是，查看优化器给出的sql执行计划，然后指定多表关联的顺序（让执行计划和测试环境一致）。
查看优化器改写后的SQL信息：
explain extended select * from ( select goy.is_replacement_order, goy.ycon_no,go.booking_req_no,go.export_org_name,go.salesman_name,go.shipping_personnel_name,gtyr.warehouse_name,gsn.delivery_order_number,go.status,gtyr.ycon_status from go_order_ycon goy left join go_order go on go.order_no = goy.order_no left join go_task_ycon_refrence gtyr on gtyr.ycon_no = goy.ycon_no and gtyr.order_no =goy.order_no left join go_shipment_notice gsn on gsn.vir_container_number = gtyr.ycon_no where (goy.ycon_no ='VCH201808280034' or goy.lcl_vir_container_number = 'VCH201808280034' or goy.ycon_no in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034') or goy.lcl_vir_container_number in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034')) ) TEMP where TEMP.ycon_status <>'Y_110' AND TEMP.status = 'O_10'\G
优化器做的SQL改写如下：
| Note | 1003 | select `midea_gls`.`goy`.`is_replacement_order` AS `is_replacement_order`,`midea_gls`.`goy`.`ycon_no` AS `ycon_no`,`midea_gls`.`go`.`booking_req_no` AS `booking_req_no`,`midea_gls`.`go`.`export_org_name` AS `export_org_name`,`midea_gls`.`go`.`salesman_name` AS `salesman_name`,`midea_gls`.`go`.`shipping_personnel_name` AS `shipping_personnel_name`,`midea_gls`.`gtyr`.`warehouse_name` AS `warehouse_name`,`midea_gls`.`gsn`.`delivery_order_number` AS `delivery_order_number`,`midea_gls`.`go`.`status` AS `status`,`midea_gls`.`gtyr`.`ycon_status` AS `ycon_status` from `midea_gls`.`go_order_ycon` `goy` join `midea_gls`.`go_order` `go` join `midea_gls`.`go_task_ycon_refrence` `gtyr` left join `midea_gls`.`go_shipment_notice` `gsn` on(((`midea_gls`.`gsn`.`vir_container_number` = `midea_gls`.`gtyr`.`ycon_no`) and (`midea_gls`.`gtyr`.`ycon_no` is not null))) where ((`midea_gls`.`goy`.`ycon_no` = `midea_gls`.`gtyr`.`ycon_no`) and (`midea_gls`.`gtyr`.`order_no` = `midea_gls`.`go`.`order_no`) and (`midea_gls`.`goy`.`order_no` = `midea_gls`.`go`.`order_no`) and (`midea_gls`.`gtyr`.`ycon_status` <> 'Y_110') and (`midea_gls`.`go`.`status` = 'O_10') and ((`midea_gls`.`gtyr`.`ycon_no` = 'VCH201808280034') or (`midea_gls`.`goy`.`lcl_vir_container_number` = 'VCH201808280034') or
手动优化改写后的SQL：
desc select * from ( select goy.is_replacement_order, goy.ycon_no,go.booking_req_no,go.export_org_name,go.salesman_name,go.shipping_personnel_name,gtyr.warehouse_name,gsn.delivery_order_number,go.status,gtyr.ycon_status from go_order_ycon goy straight_join go_order go on go.order_no = goy.order_no straight_join go_task_ycon_refrence gtyr on gtyr.ycon_no = goy.ycon_no and gtyr.order_no =goy.order_no left join go_shipment_notice gsn on gsn.vir_container_number = gtyr.ycon_no where (goy.ycon_no ='VCH201808280034' or goy.lcl_vir_container_number = 'VCH201808280034' or goy.ycon_no in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034') or goy.lcl_vir_container_number in (select lcl_vir_container_number from go_order_ycon where ycon_no ='VCH201808280034')) ) TEMP where TEMP.ycon_status <>'Y_110' AND TEMP.status = 'O_10'\G
改写后的SQL 执行计划和测试环境的一致。
=======
案例2：
限于蝙蝠，这个案例的表结构就不详细说明了。
复杂SQL的子查询中的多表关联，执行计划中表连接顺序不一样，导致sql执行效率降低。
还有一个案例是两个环境的数据库版本不一致，分别是mariadb 10.1.18, 10.4.6.
表结构、表数据量全部相同。optimize_switch 配置一致。所有相关表analyze 之后，子查询中因为表关联顺序不同，导致执行效率相差非常大。

sql 调优处理方式：
主要是根据10.1.18 中子查询的表关联顺序对10.4.6 的执行计划进行调整。
做了straight_join 修改的子查询，避免了6个10万数据量左右的全表扫描，可以很快查出结果。
可以从执行计划中 rows 一列查看子查询中的扫描行数进行确认。
