从 SAS 中的日期检索月份和年份

Question

I am comparing dates from two tables. Values1 = 28/07/2020 Values2 = 26/06/2020 I tried using the intnx function. it doesnt provide the right results. it should compare only the month and year and spit out the differences

Answer 1

intnx is for advancing or retreating a date value to another date value.

The correct function for computing intervals is INTCK .

* variables contain SAS date values;

month_diff = intck ('month', values1, values2);
