MySql5.6导出远程数据库服务器上的数据表结构出现如下错误:


mysqldump: Couldn't execute 'SELECT @@GTID_MODE': Unknown system variable 'GTID_MODE' (1193)


解决方法:

If you are using the MySQL 5.6 version of mysqldump on an older MySQL database, you might get the error message.
mysqldump: Couldn't execute 'SELECT @@GTID_MODE': Unknown system variable 'GTID_MODE' (1193)
This error is in part due to the introduction of Global Transaction Identifiers (GTIDs) in MySQL 5.6. GTIDs make it simple to track and compare replication across a master-slave topology.
mysqldump tries to query this system variable, which doesn’t exist in earlier versions, and then fails. The solution is to add –set-gtid-purged=OFF in the mysqldump command. It should look something like

mysqldump -h dbHost -u dbuser dbName --set-gtid-purged=OFF
