规格：运行 WAMP、MySQL v 5.7.14 的 Windows 10
所以这个可爱的错误引起了很多人的头疼：
14:28:30CALL storedemo.usp_GenerateAprioriRules(0.05, 50) 错误代码：1055。ORDER BY 子句的表达式#1 不在 GROUP BY 子句中，并且包含非聚合列“storedemo.tbltotalorder.itemName”，它在功能上不依赖于 GROUP 中的列BY 子句；这与 sql_mode=only_full_group_by 0.109 sec 不兼容
我已经跟踪了这里的每个线程并设置了 SQL_MODE=""，但是我仍然收到此错误。我什至通过 Wampserver 使用 MySQL 工具下的内置选项将其设置为 null。
运行这些中的每一个都会给我空值：
SELECT @@sql_mode;
SELECT @@GLOBAL.sql_mode;
SELECT @@SESSION.sql_mode;
然而，似乎 mysql 仍在执行此规则。不完全确定如何进行。附件是我的 ini 文件，它显示该选项设置为 null - 但此错误仍然存在。

;
; To configure this host as a replication slave, you can choose between
; two methods :
;
; 1) Use the CHANGE MASTER TO command (fully described in our manual) -
; the syntax is:
;
; CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
; MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
;
; where you replace <host>, <user>, <password> by quoted strings and
; <port> by the master's port number (3306 by default).
;
; Example:
;
; CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
; MASTER_USER='joe', MASTER_PASSWORD='secret';
;
; OR
;
; 2) Set the variables below. However, in case you choose this method, then
; start replication for the first time (even unsuccessfully, for example
; if you mistyped the password in master-password and the slave fails to
; connect), the slave will create a master.info file, and any later
; change in this file to the variables' values below will be ignored and
; overridden by the content of the master.info file, unless you shutdown
; the slave server, delete master.info and restart the slaver server.
; For that reason, you may want to leave the lines below untouched
; (commented) and instead use CHANGE MASTER TO (see above)
;
; required unique id between 2 and 2^32 - 1
; (and different from the master)
; defaults to 2 if master-host is set
; but will not function as a slave if omitted
;server-id = 2
;
; The replication master for this slave - required
;master-host = <hostname>
;
; The username the slave will use for authentication when connecting
; to the master - required
;master-user = <username>
;
; The password the slave will authenticate with when connecting to
; the master - required
;master-password = <password>
;
; The port the master is listening on.
; optional - defaults to 3306
;master-port = <port>
