mysqldump 远程导数据库表结构的时候，报错：
Warning: A partial dump from a server that has GTIDs will by default include the GTIDs of all transactions, even those that changed suppressed parts of the database.
If you don't want to restore GTIDs, pass --set-gtid-purged=OFF.
To make a complete dump, pass --all-databases --triggers --routines --events.
mysqldump: Couldn't execute 'SELECT COLUMN_NAME, JSON_EXTRACT(HISTOGRAM, '$."number-of-buckets-specified"') FROM information_schema.COLUMN_STATISTICS WHERE SCHEMA_NAME = 'db_informationopenserver' AND TABLE_NAME = 'bdc_conc';': Unknown table 'column_statistics' in information_schema (1109)
在添加了
--set-gtid-purged=OFF --column-statistics=0
这2个选项之后，能正常导出了
mysqldump -h xxxxx.mysql.rds.myhuaweicloud.com --set-gtid-purged=OFF --column-statistics=0 -u username -p -d db_name > test20230330.sql
