Add newest values until current date












0















So I have this query to insert data into a table (year and month are when the row was created)





INSERT INTO Table#1 (ID, col2, Year, Month)



SELECT B.ID, B.col2, A.InvoiceYear, A.InvoiceMonth



FROM Table#2 AS A



INNER JOIN Table#3 AS B ON B.ID = A.ID



ORDER BY A.InvoiceYear DESC, A.InvoiceMonth DESC





The thing is that everytime i run that query, it add all the data all over again, and i want only the newest data from the last update.
So the thing i wanted to do is adding:



WHERE A.InvoiceYear >= MAX(table#1.Year)
AND A.InvoiceMonth > MAX(table#1.Month)



The problem with it, first of all, it didnt work, and second, the maximum value for month its going to be 12, because i have data from 4 years. Is there a way to add data that the year and month is more recent that the oldest value added?



Thanks for the help, if something wasnt clear please ask me, it's not my native language
