MySQL data insertion error: Got a packet bigger than'max_allowed_packet'bytesThis
is caused by the insertion input being too large
. You can view the current value through the command:
show VARIABLES like '%max_allowed_packet%';
There can be 2 solutions:
1. Temporary modification, invalid after restarting:
mysql>set global max_allowed_packet=524288000; #修改 512M，具体数值根据情况确定
2. To modify my.cnf (my.ini under windows), you need to restart mysql.
Add a sentence to [MySQLd]the section (if it exists, just adjust its value):
max_allowed_packet=256M #（根据实际情况调整数值）
After modification, use the query command to check whether the modification is successful.
