36 views

In SQL Server, to retrieve rows where the date falls on a Saturday or Sunday, use the `DATEPART` function with the `weekday` parameter on your date column, and filter with a `WHERE` clause. For example: `SELECT * FROM YourTable WHERE DATEPART(weekday, YourDateColumn) IN (1, 7)` assuming your SQL Server is set to have Sunday as the first day of the week (1) and Saturday as the last day of the week (7). If your settings differ, adjust the numbers in `IN (1, 7)` accordingly to match Saturday and Sunday.
