MySQL 執行SQL腳本 報ERROR 1231 (42000)的解決辦法【轉】

今天在source mysqldump 備份文件時，發現導入的過程中報如下的錯誤：

ERROR 1231 (42000): Variable 'time_zone' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'sql_mode' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'foreign_key_checks' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'unique_checks' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'character_set_client' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'collation_connection' can't be set to the value of 'NULL'

ERROR 1231 (42000): Variable 'sql_notes' can't be set to the value of 'NULL'

 

解決方法：

 

mysql> set max_allowed_packet=1024M;  --只對當前會話生效

mysql> source ./xxxx.sql;

 

如果MySQL版本不允許在線修改，就只能修改my.cnf

vi /opt/my.cnf

set max_allowed_packet=1024M; 

重啟數據庫

service mysql restart
