Similarly, we can use KEEP= option to keep specific variables. The DROP= option is used to drop these two variables. Suppose you need to keep all the variables from SASHELP.CARS except variables 'MODEL' and 'MAKE'. The COUNT() function returns the number of non-missing values in a variable. You can use NMISS() function to compute the number of missing values in a variable. You can use PROC SQL with COUNT(DISTINCT variable_name) to determine the number of unique values for a column.

Use the WHERE clause with any valid SAS expression to subset data.
