  • Date manipulation in SQL means performing operations to extract, calculate, or adjust date/time values.
  • We can extract parts like YEAR(OrderDate), MONTH(OrderDate), or DAY(OrderDate).
  • In my project, we calculated Order Aging using DATEDIFF(day, OrderDate, GETDATE()).
  • Functions like DATEADD() adjust dates, e.g., adding 7 days for delivery estimates.
  • FORMAT() or CONVERT() changes date display for reporting purposes.
  • Filtering by date range is done using WHERE OrderDate BETWEEN '2024-01-01' AND '2024-12-31'.
  • We also created quarters and fiscal periods using expressions.
  • Date manipulation at source reduces processing in Power BI.
  • It ensures correct trend analysis and time-based KPIs.
  • So SQL date operations prepare clean temporal data for reporting and dashboards.
