SQL Server date comparisons based on month and year only

Question

I am having trouble determining the best way to compare dates in SQL based on month and year only.

We do calculations based on dates and since billing occurs on a monthl

Answer 1

You can join on MONTH and YEAR values of those dates:

SELECT * 
FROM tableName 
WHERE YEAR(@date1) = YEAR(@date2) AND MONTH(@date1) = MONTH(@date2)
