SQL Server 2019: implementing Date Range Filtering in Aggregated Query
I tried several approaches but none seem to work. I'm working on a personal project and I'm relatively new to this, so bear with me. I'm trying to debug I'm working on a personal project and I'm running into a question when trying to filter records based on a date range in an aggregated query in SQL Server 2019... The goal is to calculate the total sales for a specific product within the last month, but my query is returning results that don’t seem to honor the date range I specified. Here's a snippet of the query I'm using: ```sql SELECT SUM(sales_amount) AS total_sales FROM sales WHERE product_id = @ProductId AND sale_date BETWEEN DATEADD(MONTH, -1, GETDATE()) AND GETDATE() ``` I have verified that the `sale_date` column is of type `DATETIME`, and I even tested the date range manually by executing: ```sql SELECT COUNT(*) FROM sales WHERE sale_date BETWEEN DATEADD(MONTH, -1, GETDATE()) AND GETDATE() ``` This returned the expected number of transactions, which means the data exists as expected. The scenario arises when I include the `SUM` aggregation; it returns a value of `0` even when I know there have been sales in that date range. I've also tried replacing `BETWEEN` with `>=` and `<=`, but the results remain the same. I suspect it might be related to how SQL Server handles the `DATETIME` type or possibly how aggregation interacts with filtering, but I need to seem to pinpoint the scenario. I've also checked for any possible triggers or constraints that might be affecting the outcome and found none. How can I ensure that my aggregated query correctly reflects the total sales within the specified date range? For context: I'm using Sql on macOS. Has anyone else encountered this? I'm working with Sql in a Docker container on macOS. Is there a simpler solution I'm overlooking? I'd love to hear your thoughts on this. What are your experiences with this?
