Does Oracle Support Date Data Type?


Scott Campbell

Oracle is a powerful database management system that offers a wide range of data types to store and manipulate data. One common question that arises when working with Oracle is whether it supports the date data type. In this article, we will explore the answer to this question in detail.

What is the Date Data Type?

The date data type is used to store dates and times in a database. It allows you to perform various operations such as comparison, arithmetic calculations, and formatting on dates. The date data type is essential when dealing with applications that require tracking events or scheduling tasks based on specific dates and times.

Oracle’s Date Data Type

Oracle does support the date data type, which is called ‘DATE’. When you create a table in Oracle, you can define a column with the date data type to store dates and times.


    order_id   NUMBER,
    order_date DATE,
    -- Other columns

In the above example, the ‘order_date’ column is defined with the ‘DATE’ data type, allowing us to store dates associated with each order.

Date Format in Oracle

When working with dates in Oracle, it’s essential to understand the default format used for displaying dates. By default, Oracle displays dates in the ‘DD-MON-YY’ format (e.g., 01-JAN-21).

If you want to display dates in a different format or parse strings into date values, you can use conversion functions like TO_CHAR() and TO_DATE(). These functions allow you to specify custom date formats based on your requirements.

Date Manipulation in Oracle

Oracle provides a wide range of functions to manipulate date values. These functions allow you to perform operations like adding or subtracting days, months, or years from a given date, extracting specific components from a date (e., year, month, day), and formatting dates in different ways.

  • ADD_MONTHS(): Adds a specified number of months to a given date.
  • SYSDATE: Returns the current system date and time.
  • EXTRACT: Extracts a specific component (e., year, month, day) from a date.
  • TO_CHAR(): Converts a date value into a character string using a specified format.

These functions provide great flexibility when working with dates in Oracle, allowing you to perform complex calculations and transformations on your data.

In Conclusion

In summary, Oracle does support the date data type. You can define columns with the ‘DATE’ data type to store and manipulate dates in your database.

Oracle also provides various functions to handle date manipulation and formatting according to your specific needs. Understanding how to work with the date data type in Oracle is crucial for building robust applications that rely on accurate date tracking and calculations.

I hope this article has provided you with valuable insights into Oracle’s support for the date data type. Now you can confidently use the ‘DATE’ data type in your database designs and leverage its powerful features when working with dates in Oracle.
