The examples below range from simple to more complex.īe sure to run PROC CONTENTS periodically to see the changes that are made to the variables.Įxample 9 contains the code for "Putting it all together".Įxamples 10 and 11 show how to perform these actions on a variable in a data set.

Numeric to character sas full#
How do you convert a numeric value to a SAS date?Ĭlick the Full Code tab to see the solution for this question and many more examples.įor even more information about converting values, see the following SAS tutorial video: You want it to be a SAS date with a format that displays the value as 10122012. This looks like a SAS date, but when you use PROC CONTENTS, you see that there is no format applied, so it is actually the integer value 10122012.
Start with a numeric variable with a value of 10122012 as an example. Both of these steps are needed to convert a numeric value that looks like mmddyyyy but is not a SAS date, to a SAS date.
You have seen how to convert numeric values to character and character values to numeric. The end result is a SAS date that looks the same as the original variable, but can be analyzed and manipulated by the date functions:Ĭhar_var = put(num_var, 10. The following code starts with a character string "12JUL2016", creates a SAS date, and then formats it with the DATE9. reads date values in the form ddmmmyy, which matches 12JUL2016. Look at the date informats to determine which informat matches your values. If it is a character variable, you can convert it to a SAS date so that you can take advantage of the SAS date functions. Is Startdate a character string "12JUL2016" or is it a numeric variable with a format applied? You can use PROC CONTENTS to verify the variable type and to see whether a format has been applied to it. A SAS date might be formatted so that it contains characters in the display, but it is always stored as a numeric variable.įor example, suppose you receive a data set that contains a variable named Startdate that is displayed in PROC PRINT output as 12JUL2016. Run Using the INPUT function to convert a character date to a SAS dateĪ SAS date is a numeric value with which you can use date functions and calculations.
