In attempting to use the mysqldump utility provided with MySQL 8.x against a 5.7 server, you may receive the following error message:
mysqldump: Couldn't execute 'SELECT COLUMN_NAME, JSON_EXTRACT(HISTOGRAM, '$."number-of-buckets-specified"')This is due to the INFORMATION_SCHEMA in 8.0 having more columns to support several new features in 8.x. This error can be silenced by adding the following parameter to the mysqldump command line:
--column-statistics=0
