| I want to aggregate the previous 3 months of data that I have. Is there a way to do this using something like getdate() -1, getdate() -2, getdate() -3. Thanks! |

| SELECT SUM(col1) FROM myTable WHERE dateCol>=DATEADD(month, -3, GETDATE())That is sensitive to day of month and time values. If you want the entire calendar month to be included:SELECT SUM(col1) FROM myTable WHERE dateCol>=DATEADD(month, DATEDIFF(month, 0, GETDATE())-3, 0) |
