In Oracle SQL, the data type used to store dates is called DATE. The DATE data type allows you to store and manipulate date values in a format that is easy to work with.

Working with Dates in Oracle SQL

Dates are an important part of any database application. They are used to store information about events, appointments, and various time-related data. In Oracle SQL, the DATE data type provides a way to represent and handle dates effectively.

The Syntax for Declaring a Date Column

To declare a column of type DATE, you can use the following syntax:

  • column_name DATE;

Inserting Date Values into a Table

To insert date values into a table, you can use the TO_DATE() function:

  • INSERT INTO table_name (date_column) VALUES (TO_DATE('2022-01-01', 'YYYY-MM-DD'));

Date Formatting in Oracle SQL

In Oracle SQL, you can format dates using the TO_CHAR() function. This function allows you to convert a date value into a specific string format:

  • SELECT TO_CHAR(date_column, 'YYYY-MM-DD') FROM table_name;

Date Functions in Oracle SQL

In addition to storing and retrieving dates, Oracle SQL provides several built-in functions for manipulating date values. Some commonly used date functions include:

  • SYSDATE: Returns the current date and time.
  • ADD_MONTHS: Adds a specified number of months to a date.
  • MONTHS_BETWEEN: Calculates the number of months between two dates.
  • TRUNC: Truncates a date value to a specified unit (such as day, month, or year).


The DATE data type in Oracle SQL provides a reliable and efficient way to work with dates. It allows you to store and manipulate date values effectively, and offers various functions for performing date calculations. By understanding how to work with the DATE data type and its related functions, you can confidently handle date-related operations in your Oracle SQL applications.
