问题记录：mysqldump 出现 Unknown table ‘column_statistics‘ in information_schema

mysqldump 出现如下问题

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

解决办法 增加参数 --column-statistics=0

mysqldump -uroot -p -P53306 test-db --column-statistics=0 > test-db.sql.gz
