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

查了一下，由于目标服务器用的是MySQL 5语法，在导出时添加--column-statistics=0参数以兼容。
