第一行定义了HASH对象名称,object可以是HASH或HITER,HASH对象名由编程者定义。 第二行和第三行分别通过HASH对象名.method的语法定义了HASH对象的KEY变量和DATA变量,这些变量都是DATA步中的变量。 第四行表明HASH对象定义结束。 示例,将work.product中的变量Product_Name和Description的数据加到数据集work.sales中。 da...

SAS 对数据的拼接与串接 使用SAS对数据进行串接、合并、更新与修改。 1. 数据集的纵向串接 数据集的纵向串接指的是,将两个或者多个数据集首尾相连,形成 一个新的数据集。 对数据集的纵向串接可以通过以下两种方法实现: 1.1 使用SET语句实现纵向串接 1.基本形式 使用SET语

unconstrained delegation (DCs have this by default), we can use the printerbug to force the DC of the external forest's root domain to authenticate to us. Then we can capture it's TGT, inject it into memory and DCsync to dump it's hashes, giving ous complete access over the whole ...
In addition to numerous tuning techniques, this book also touches on implicit and explicit pass-throughs, presents alternative SAS grid- and cloud-based processing environments, and compares SAS programming languages and approaches including FedSQL, CAS, DS2, and hash programming. Other topics include...
