DATEADD Syntax in SQL Server

Basic Syntax Format

DATEADD (datepart, number, date)

• datepart: Which part of the date to add (e.g., day, month, year)

• number: How much to add (positive or negative integer)

• date: The starting date or datetime value

Note: SQL Server syntax uses keywords like day, month, year for datepart—these may differ from MySQL or PostgreSQL.
