DATEADD in Oracle - Examples & AI Generator

Working with dates across different databases can be tricky, especially when you're used to DATEADD in SQL Server or PostgreSQL. However, Oracle doesn’t have a direct DATEADD function. Instead, it uses arithmetic or the INTERVAL keyword to manipulate date values. This makes remembering exact syntax across databases time-consuming—unless you use an AI SQL generator like AI2sql. Instantly create correct, Oracle-specific date queries from plain English, with no coding required.

DATEADD Syntax in Oracle

Oracle handles date addition differently. Instead of DATEADD, use:

• date_column + NUMBER for days

• date_column + INTERVAL 'n' DAY for specific intervals

• date_column + INTERVAL 'n' MONTH / YEAR, etc. for months, years

This Oracle DATEADD syntax differs from SQL Server’s DATEADD(datepart, number, date) approach.

DATEADD Examples You Can Generate Instantly
