下面是测试dul工具从exp文件中直接抽取数据,使用scott这个用户来测试
欢迎大家加入ORACLE超级群:17115662 免费解决各种ORACLE问题,以后BLOG将迁移到http://www.htz.pw

2,dul导出某张表
dul在处理exp文件的时候,可以不需要配置任何的参数文件,下面先来看看使用到的两条命令的语法
SCAN DUMP FILE dump file name Scans an export dump file to produce to provide the UNEXP [TABLE] [ owner . ] table name To unload data from a corrupted exp dump file. No special setup |
