选择【OceanBase 导数工具】，随便填写信息，然后可下载。

工具下载链接如下：

https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/ob_loader_dumper/4.3.3.1/ob-loader-dumper-4.3.3.1-RELEASE.zip

上传到linux主机后解压即可使用。

需确认安装了java1.8以上版本可运行：

[root@ob ~]# java -version

java version "1.8.0_221"

Java(TM) SE Runtime Environment (build 1.8.0_221-b11)

Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

注意：

csv文件格式必须为"表名.xxx.csv"或"表名.csv"的格式，可自动识别。否则导入失败忽略。

参数--skip-header跳过第一行csv的标题行。如果导入或导出所有，则指定—all参数。

 

导出csv:

如果指定--all则导出所有表
