How do you reorder variables in a SAS dataset?

You can control the order in which variables are displayed in SAS output by using the ATTRIB statement. Use the ATTRIB statement prior to the SET, MERGE, or UPDATE statement in order for you to reorder the variables. Variables not listed in the ATTRIB statement retain their original position.

How do you retain variables in SAS?

The RETAIN statement simply copies retaining values by telling the SAS not to reset the variables to missing at the beginning of each iteration of the DATA step. If you would not use retain statement then SAS would return missing at the beginning of each iteration. The retain statement keeps the value once assigned.

How do I order columns in a SAS dataset?

SAS arranges columns in a dataset according to the order in which the variables are declared or defined, so any variables declared prior to the SET statement will be placed first in the resulting output dataset.

What is the order of variables in enum?

What is the order of variables in Enum? Explanation: The compareTo() method is implemented to order the variable in ascending order.

How do you change columns in SAS?

Modifying a Column You can use the MODIFY clause to change the width, informat, format, and label of a column. To change a column’s name, use the RENAME= data set option. You cannot change a column’s data type by using the MODIFY clause.

What is the retain statement in SAS?

The RETAIN statement specifies variables whose values are not set to missing at the beginning of each iteration of the DATA step. The KEEP statement specifies variables that are to be included in any data set that is being created.

How do you arrange variables?

Sorting variables will rearrange the order of the variables (columns) in your data. Variables can be sorted on only one attribute at a time: Name, Type, Width, Decimals, Label, Values, Missing, Columns, Align, Measure, or a custom attribute.

Which class does all the enum extend?

All enumerations internally extend a class named Enum the base class of all the language enumeration types. Since Java doesn’t support multiple inheritance you cannot extend another class with enumeration if you try to do so, a compile time error will be generated.

How to reorder variables in a SAS data set?

Instead, you can either use the FORMAT statement for data steps or the SELECT statement for PROC SQL as it has the same effect without compromising on the data. I would personally use and prefer the FORMAT statement to reorder the variable list. So, this was our side to reorder variables in a SAS dataset.

What is a retain statement in SAS?

A RETAIN statement allows you to tell SAS not to set missing values to the variables during each iteration of the data step. In the above example, SAS resets the values of cum_sum to missing for each observation.

What is the use of retainer in SAS?

Without a RETAIN statement, SAS automatically sets variables that are assigned values by an INPUT or assignment statement to missing before each iteration of the DATA step. Use a RETAIN statement to specify initial values for individual variables, a list of variables, or members of an array.

Can retain statements be used to reorder variables?

For example, RETAIN is used to retain, or carry values across iterations of a DATA step. If RETAIN is used for this purpose, AND to reorder the data, there’s a risk of errors and/or unexpected results. The ability of these statements to reorder variables is simply a by-product of how they operate.
