mysql常见错误

1、导出数据时遇见

mysqldump: Couldn't execute 'SELECT COLUMN_NAME,                       JSON_EXTRACT(HISTOGRAM, '$."number-of-buckets-specified"')                FROM information_schema.COLUMN_STATISTICS                WHERE SCHEMA_NAME = 'www_xxx_com' AND TABLE_NAME = 'aaa_xxxx';': Unknown table 'COLUMN_STATISTICS' in information_schema (1109)

因为新版的mysqldump默认启用了一个新标志，通过--column-statistics=0来禁用他
