问题 i am trying to run the 'describe table_name' command on oracle. I am using dbeaver for accessing oracle. But, when i run the command, it shows SQLException and error message "invalid sql statement". How can i perform the operation? 回答1: describe is not a SQL statement, otherwise it would have been documented in the SQL language reference: https://docs.oracle.com/database/121/SQLRF/toc.htm The documentation for the describe command can be found in the SQL*Plus command reference: https://docs

问题 Apologies if this is in some way a duplicate - I couldn't find anything that covered this (at least in a way that I could understand made it similar). Here's a basic diagram of my connections: Laptop => SSH server 1 => SSH server 2 => MySQL (MariaDB) I can use terminal to jump across to server 2 as per the usual methods: ssh -t user@server1 ssh -p99 user@server2 Then, in the terminal, I can mysql -uroot -p as normal.

  今天首次使用DBeaver软件链接数据库时会进行下载驱动文件,例如如下图所示:   在上图中显示了下载驱动文件失败,提示“无法解决库文件,请检查网络设置”。其实,是可以正常上网的,可能是公司内网的限制,或者是国外镜像地址无法访问。根据这情况,先检查是不是公司内网限制所致。点击上图中的左半部分图“下载配置”项,会弹出如下图所示的对话框:   在上图中,我设置了在公司内网的HTTP代理后进行下载操作,还是提示下载失败;这可能是无法访问外部的镜像地址了,那是否可以采用公司内网的maven下载地址呢?我不妨进行了试用;在上图中的左部分选项中,点击“驱动”,会展开子选项,如下图所示(可能展示的图与下图不一致,不过没有关系):   在上图中的右半部分,添加新的maven仓库,如下图所示:   在url中填写公司内部的maven仓库地址即可,新添加的maven仓库地址默认是放在仓库列表中的最底部,我们可以将我们新添加的maven仓库向上移动到仓库列表的最顶部;然后依次点击“应用”----->"Apply and Close"按钮,再次进行下载,这次下载成功了,如下图效果所示:   从上图中我们可以看到SQLite已能够正常链接上了,说明我们的驱动文件已经下载好了。至此,我们就可以正常使用DBeaver进行操作数据了。 20191028 闪 来源:博客园 作者: 晒太阳的兔子 链接:https
