Hash tablesare implemented in SAS as objects and provide a wide range of functionality through their methods and properties. 2. SAS中HASH 对象的创建: Declarethe hash object.定义hash对象 Create aninstanceof (instantiate) the hash object.创建一个实例 Initialize lookupkeysanddata.初始化 key 和 变量。
SAS as Part of JavaSAS DATA step gives us the ability to communicate with external Java programs and therefore opens awhole different programming world. ... CAJ Object 被引量: 0发表: 2015年 USING SAS HASH OBJECTS TO CUT DOWN PROCESSING TIME Hash tables are in existence since SAS 9 version...
Examples show the use of the SAS hash object methods FIND(), REPLACE(), and OUTPUT() to addnew records and overwrite and partition existing records in the agent dimension table. An example of the hashiterator and use of the LAST() method illustrates how to determine the last key in the ...
Being new to SAS, I did a lot of research and it appears that hash tables would be the best approach but there are several aspects to the programming that are not clear to me. My initial approach (and please direct me if there is a better approach) is to use the hash ...

另外,论文[SIGMOD 2015]Rethinking SIMD Vectorization for In-Memory Databases基于先进的SIMD指令,例如gathers和scatters,提出了一种新的向量化执行引擎,并给出了selection scans、hash tables、partition的向量化实现代码,在这些基础上,实现了sort和join等算子。详细内容见[SIGMOD 2015]Rethinking SIMD Vectorization for In...

FilterHashtable accepterar en hash-tabell som ett filter för att hämta specifik information från Windows-händelseloggar. En hash-tabell använder nyckel/värde-par . Mer information om hash-tabeller finns i about_Hash_Tables.
The introduction of hash objects with SAS version 9 brought about new opportunities for novel programming techniques. The recent discovery that hash tables can contain even other hash objects, also known as the 'hash of hashes', opens the door to their application to hierarchical data structures....
