这个错误通常出现在使用R语言中的DBI包和ODBC驱动程序时。它表示您尝试使用已经关闭或已删除的数据库连接或查询对象。
要解决此问题,您可以尝试重新连接数据库以获取新的连接对象,或者检查您的代码以确保正确关闭连接和查询对象以避免发生这种错误。您还可以尝试更新DBI包和ODBC驱动程序以获取最新版本,以避免已知的错误和漏洞。

这个错误通常发生在 R 语言中使用数据库进行查询时,可能是因为查询的表或者列被删除或者清除了。你可以检查一下查询的语句是否正确,以及查询的表或者列是否存在。如果确认查询的语句和表或者列都是正确的,那么可以尝试重启 R 语言或者重新连接数据库。如果问题仍然存在,可能需要联系数据库管理员或者开发人员进行进一步的处理。
--set-gtid-purged
SET GTID_PURGED is a MySQL system variable that is used to control the global transaction identifier (GTID) state of the server. It sets the list of purged transactions, which means that the server will not replicate any transactions that occurred before the specified GTID.
When we set GTID_PURGED, we are telling MySQL that we are purging all transactions up to a certain point in time, and that all transactions before this point should not be replicated. This can be useful when we are setting up a new server and want to ensure that we only replicate data from a certain point forward.
To set GTID_PURGED, we can use the following command:
```
SET GLOBAL gtid_purged='GTID1, GTID2, GTID3';
```
Where GTID1, GTID2, GTID3 are the GTIDs that we want to purge up to.
Note that setting GTID_PURGED incorrectly can cause replication issues, so it is important to ensure that we have the correct GTIDs before setting it.
