SQL Dates

SQL Dates is a feature in SQL that allows you to store, filter, and manipulate date and time values in your tables. These date-related fields are useful for tracking when events happen like order dates, birthdates, or appointment times.

In SQL, handling dates correctly is important because query results depend on how the date values are stored (with or without time) and whether the format matches. Many common tasks in SQL involve comparing dates, finding records within a certain range, or calculating differences between dates.

SQL Dates Syntax

SQL provides several date and time data types to store information related to dates and timestamps. The most commonly used ones include:

Common SQL Date Data Types:

Data TypeFormatNotes
DATEYYYY-MM-DDOnly the date
DATETIMEYYYY-MM-DD HH:MI:SSIncludes both date and time
TIMESTAMPYYYY-MM-DD HH:MI:SSAutomatically updated in some systems
YEAR (MySQL)YYYY or YYOnly the year (not available in all systems)

Important: Date/time handling and functions may vary across databases. Our playground supports basic DATE and DATETIME types, but functions like GETDATE() or CURRENT_TIMESTAMP may not work, depending on the SQL engine behind our playground. Always test and adjust accordingly.

SQL Dates Example

Let’s create a simple Orders table with a DATE column and insert some sample records:

SQL

Now insert some rows into the table:

SQL

Query to filter by date:

This query returns all orders made on November 11, 2008:

SQL Dates With Time Components

If your order_date column includes a time (i.e., is stored as a DATETIME), filtering by just the date still works in our playground:

SQL

This will return records where the date matches 2008-11-11, even if the time is included.

In other SQL environments, if exact matching fails due to time, you can use functions like:

SQL

Or use a range:
