【MySQL】1260 – Row 62 was cut by GROUP_CONCAT()已关闭评论
场景：在INSERT…. SELECT GROUP_CONCAT() ….时，提示【1260 – Row 62 was cut by GROUP_CONCAT()】错误。
原因：group_concat长度限制默认是1024，当超出1024则会出现此错误。
解决办法：
1：永久解决
|
1 2 3 4 |
[root@DB8 ~]# vi /etc/my.cnf …… # 增加以下参数 group_concat_max_len = 1024000 |
2：临时解决
1）全局会话
|
1 2 3 4 |
mysql> SET GLOBAL group_concat_max_len = 10240000; Query OK, 0 rows affected mysql> |
2）当前会话
