MySQL故障案例 | mysqldump: Couldn’t execute ‘SELECT COLUMN_NAME
原创
mysqldump 导数据出现如下错误
mysqldump: Couldn’t execute ‘SELECT COLUMN_NAME, JSON_EXTRACT(HISTOGRAM, ‘$.“number-of-buckets-specified”’) FROM information_schema.COLUMN_STATISTICS WHERE SCHEMA_NAME = ‘wx_service’ AND TABLE_NAME = ‘add_user’;’: Unknown table ‘column_statistics’ in information_schema (1109)
查看官网内容得知：
- --column-statistics
Add ANALYZE TABLE statements to the output to generate histogram statistics for dumped tables when the dump file is reloaded. This option is disabled by default because histogram generation for large tables can take a long time.

解决方法：
添加禁用参数：--column-statistics=0
mysqldump --column-statistics=0END
