![]() In the examples below, we show how to use this method to add a suffix/prefix to all variables, and how to change variable names with the same pattern. You can use the SAS dictionary tables and a SAS macro variable to change all variable names at once. So, how can you rename all variables in a SAS dataset? However, if you have a dataset with many columns and you want to rename all of them, explicitly specifying all names can be a bothering task. Up till now, we have explicitly specified in the RENAME option which variable name(s) we want to change. Between parenthesis, we write the name of the column we want to change, an equal sign, and the new column name. We use the RENAME option as a dataset option in the SET statement. We want to change the name of variableA to FirstColumn. Our small sample dataset has three columns, namely variableA, variableB, and columnC. ![]() ![]() In this example, we show how to rename one variable in a SAS dataset. So, you should use the new variable name in the WHERE option.
