If more than one data set name appears in the SET statement, the resulting output data set is a concatenation of all the data sets that are listed. SAS reads all observations from the first data set, then all from the second data set, and so on, until all observations from all the data sets have been read.
Provides comprehensive reference information for the Base SAS language, which is available in all operating environments that support SAS. This document is organized by data set options, formats, functions and CALL routines, informats, statements, system options, and component options.
See Interleaving SAS Data Sets for an example of BY group processing with the SET statement. Combining SAS Data Sets Use a single SET statement with multiple data sets that are specified to concatenate the specified data sets. That is, the number of observations in the new data set is the sum of the number of observations in the original data ...

The WHERE statement can produce a different data set from the subsetting IF when a BY statement accompanies a SET, MERGE, or UPDATE statement. The different data set occurs because SAS creates BY groups before the subsetting IF statement selects but after the WHERE statement selects.
10/24/2012 · The subsetting IF statement tests if they meet the entrance criteria. The second SET statement will be the list of randomizations. So only subjects that meet the criteria make it past the IF statement. Then the second SET statement adds in the values of the variables from the randomization file (randomization number, treatment, etc.).
2/25/2014 · In this video, you learn how to use a SET statement in the DATA step to read a SAS data set using Base SAS. The DATA step is a very powerful tool for data manipulation. For more tutorials, visit ...
I am trying to use the set statement for multiple datasets in one shot namely I have datasets vmoreranked1,vmoreranked2,vmoreranked3,...But Communities SAS Procedures
6/20/2016 · Every beginning SAS programmer learns the simple IF-THEN/ELSE statement for conditional processing in the SAS DATA step. The basic If-THEN statement handles two cases: if a condition is true, the program does one thing, otherwise the program does something else. Of course, you can handle more cases by using multiple ELSE IF statements.
We again use a Set statement to combine the two data sets, but with the GIRLS dataset being first. In this case, we don't need to use a length statement, because the GIRLS dataset has a length of 10 for the variable Name, so SAS will pick up the characteristics of the variable Name from the GIRLS dataset.
In SAS 9.4M3, multi-table SET statements and a SET statement with embedded SQL code can be executed inside the database when you are using the SAS In-Database Code Accelerator. If you are using the SAS In-Database Code Accelerator for Hadoop, Hive .13 or later is required.
Most SAS data steps actually end when the step executes a SET or INPUT statement and finds there is no more input available. That is what is happening. SAS normally writes the observations at the end of the data step iteration. The exception is when you have an explicit OUTPUT statement coded.
SAS Do loop over Set statement. 0. SAS - Do Loops Iterations. 1. SAS: Change dataset with loop count into append statement. 0. SAS macro loop to loop through datasets in Set statement. Hot Network Questions Real-world applications of fields, rings and groups in linear algebra.
Chapter 1: The RETAIN Statement 3 Notice that the value of X is a missing value at the top of the DATA step (before the INPUT statement). This is the usual way that a SAS DATA step operates.
An IF-THEN-ELSE-IF statement consists of a boolean expression with a THEN statements. This ia again followed by an ELSE Statement. Syntax. The basic syntax for creating an if statement in SAS is − IF (condition1) THEN result1; ELSE IF (condition2) THEN result2; ELSE IF (condition3) THEN result3;
The variable a is set equal to x, but before the set statement. Thus the first time it executes, no observation has been loaded and x is missing. After setting a to missing, SAS proceeds to the set statement and loads the first observation, so x is 1. When the other code is complete, SAS then goes to the top of the data set.
Why SAS Is the Analytics Leader. Through our innovative, trusted technology and passionate connection to the progress of humanity, SAS empowers and inspires our customers to move the world forward by transforming data into intelligence.
The LIBNAME statement consists of 3 parts: 1. LIBNAME This tells SAS to create a new library. 2. Library Name The second part of the LIBNAME statement is the library name. In our example, it is PROJ1. 3. Directory Path Lastly, you will have to associate the library with a shared folder. In our example, the directory path to the shared folder is:
What Does SET Do? Each time the SET statement is executed, SAS reads one observation into the program data vector. SET reads all variables and all observations from the input data sets unless you tell SAS to do otherwise. A SET statement can contain multiple data sets; a DATA step can contain multiple SET statements.
CASE WHEN in SAS DATA statement. I have a data set in SAS in which I merged 6 other tables to. Some ID's were not in each of the other data sets so there are columns in my merged table that are null. I want these null columns to read No. I'm trying to use CASE …
Home » SAS » SAS : Where Statement and Dataset Options. SAS : Where Statement and Dataset Options Deepanshu Bhalla 6 Comments SAS. The WHERE statement is an alternative to IF statement when it comes to subsetting a data set. Basic Data Subsetting ... WHERE = Data Set Option 1. In the example shown below, the WHERE= data set option is used to ...
1/6/2016 · The set statement puts the data from the data set weight (created above) into a new data set called weight_new. Because the data set weight already exists within SAS, no input statement is necessary. Note that the structure and contents of the new data set weight_new are identical to those of the SAS data set weight.
Most SAS programmers would agree that they use the SET statement without giving much thought to the syntax, because it’s such a widely used statement of choice. We routinely name the expected data sets and possibly a few options, and away we go. A visit to the documentation can be saved for more complex concerns such as arrays, hash tables, and regular expressions.
3. The WHERE statement is more efficient than IF statement. It tells SAS not to read all observations from the data set. Look at the LOG (shown below) after using WHERE statement, you only see a count of the number of observations that meet the criteria in the WHERE statement. Only 6 observations were read from the dataset READIN.
3 The two data sets are combined with a SET statement. 4 The output from PROC PRINT shows the two data sets combined 'tot-to-bottom'. You can concatenate as many data sets as you want with a SET statement. This method forces SAS to read every observation in each of the data sets being combined. Concatenation using the SET statement
The IF-THEN-ELSE Statement in SAS. The IF-THEN-ELSE statement is used to conditionally process statement(s) when certain condition(s) are met. Let's look at some examples. The data set above contains 10 students and their exam results. IF-THEN Statement. The IF-THEN statement tells SAS to execute a statement if the condition specified is true.
Then, we'll close out the lesson discussing the process SAS follows when reading in a SAS data set. Learning objectives & outcomes. Upon completing this lesson, you should be able to do the following: use a SET statement to read data into a SAS data set from another SAS data set
A.1 SAS EXAMPLES SAS is general-purpose software for a wide variety of statistical analyses. The main ... set up by the UCLA Statistical Computing Center. A useful SAS site on-line with ... than numbers requires an accompanying $ label in the INPUT statement. (But, of course, if you are already a SAS user, you know this and much more!)
Again, the subsetting IF statement is pretty straightforward, and therefore probably also doesn't deserve any explanation. Launch and run the program, and review the output to convince yourself that only golf courses whose par is greater than 70 were included in the temporary penngolf data set. You might also want to take note that the resulting data set is the same as the resulting data set ...
In SAS, you can use either the MERGE statement or the UPDATE statement in a DATA step to update the values of observations in a master data set. Both statements should be followed by the BY statement, which specifies the primary key (variable) sorted by the SORT procedure.. The MERGE statement automatically replaces all existing values with new values, whether they are missing or not.
