1.复制sas，从一个逻辑库到另一个逻辑库 2.对SAS文件从命名 3.删除数据 3.列出逻辑库里的数据集 4.列出（修改）数据集的变量属性 5.其他...
I can think of 4 ways to copy one dataset to another inside the same library: Data step -- very easy, the first thing everyone learns, but it's kind of slow and wastes resources The X command -- using the operating system, but that's not really SAS One PROC DATASETS using an A...
If you don't use thelibrary=option, SAS will consider theWORKlibrary as the default library for managing datasets in the PROC DATASETS. Sample Datasets Let's create two datasets in the WORK library from the SASHELP library. These datasets will be used in further examples. data cars; set s...
proc delete就讲这些,应该来说,proc delete能实现的功能,在proc datasets都能实现。 二:proc datasets Section1:proc datasets能实现各种各样的功能,删除数据集只是其中的功能之一,这个过程步还能实现重命名、复制、甚至修复数据集的功能。 The PROC DATASETS statement identifies the SAS data library containing the ...
The DATASETS procedure provides the most diverse selection of capabilities and features of any of the SASprocedures. It is the prime tool that programmers can use to manage SAS data sets, indexes, catalogs, etc. Many SAS programmers are only familiar with a few of PROC DATASETS's many capabil...
Except for COPY-ing, PROC DATASETS does not produce new SAS data sets. So, your use of the DATASETS procedure will primarily be to modify the features of existing SAS data sets or other members of data libraries. The following sections provide the information that you need to make the ...
This paperintroduces PROC MIGRATE and compares it to migrating with the traditional methods - PROC COPY, PROCCPORT/PROC CIMPORT, and PROC CATALOG. SASalso provides tools that can help you validate the content and attributes of your data after conversion. We discussways to use PROC DATASETS, ...
Below is a collection of PROC APPEND SAS®papers. PROC APPEND is very useful when you need to append two or more datasets of the same structure. See alsoPROC SQL. See alternativePROC DATASETSandSETstatement. PROC DATASETS; DELETE A; /* Best Practice to first delete dataset A */ ...
A syntax error might occur when you use the DATASETS procedure (PROC) to change the name of a table with SAS/ACCESS Interface to Greenplum. For example, the following code could generate the error and the error message: libname glib greenplm dsn=
IML —恰似人间惊鸿客,墨染星辰云水间。 01 proc iml是SAS中的一个矩阵语言,它可以简化矩阵运算和自定义统计算法。...不过,proc iml和matlab也有一些不同点,比如: proc iml是SAS中的一个过程,它可以和其他SAS过程、DATA步骤和宏语言相互调用,而matlab是一个独立的软
