数据索引的创建有三种方式:data步骤、sql步骤、datasets步骤。其中还是有点困惑在data与datasets的区别之上,datasets是对逻辑库中数据集进行操作的方式,而data之后是代表程序的开始。 1、data方式创建索引 代码语言:javascript 代码运行次数:0 运行 AI代码解释
This will produce one dataset, by the mygroup variable - you can apply this logic to anything in SAS, sometimes a change to your data is needed. View solution in original post 0 Likes 5 REPLIES Kurt_Bremser Super User Re: How to append datasets when the dataset na...
Virtually all SAS programmers (with apologies to diehard SQL codeslingers) tend to use a simple SET statement in the DATA STEP when concatenating two or more datasets in their programs. Use of the SET statement is generally the most logical and practical approach because the required code is ...

Lets say if variables have different lengths in the all of the given data sets.How will i append that data.Just to understand how the process works? It probably makes more sense to explain the process that creates the datasets and fix that so that they are always created with the same ...
Note how I present example data in data steps with datalines, for easy use by others (just a copy/paste and submit is needed to reliably recreate the dataset). See it as a basic courtesy for potential helpers. Maxims of Maximally Efficient SAS ProgrammersHow to convert datasets to data step...
Assuming all the data sets have the same variables, you can also use the "open=defer" option which tells sas to re-use the same input/output buffer in memory for all the data sets, instead of creating a buffer for each incoming data set (i.e. about 61 buffers for 61 datasets for ...

I have two datasts and want to append them together( variable attributes are same in both the datasets) DATASET1(BASE=) ID IN1 OUT1 IN2 OUT2 IN3 OUT3 IN4 OUT4 DATASET2(DATA=) ID IN1 OUT1 IN2 OUT2 When I try to append these two datasets I get messages in the LOG that IN...
