Casting Date Values
As long as the column values are correctly casted to the DATE type, we can be sure that they are properly formatted already. PostgreSQL provides the ::DATE syntax for this purpose.
Syntax:
SELECT * FROM table_name WHERE date_column::DATE BETWEEN 'start_date'::DATE AND 'end_date'::DATE;
- table_name: Write your table’s name.
- date_column: Write the name of the column that contains dates.
- Specify start_date and the end_date respectively.
Example: Query retrieves the events between February 1, 2023, and April 30, 2023, casting date values explicitly.
SELECT * FROM events WHERE event_date::DATE BETWEEN '2023-02-01'::DATE AND '2023-04-30'::DATE;
Output:
Explanation: Such a query will list the events, which refers to all columns of the events table, where the event_date occurs in the dates between February 1, 2023 and April 30, 2023.
How to Select Dates Between Two Dates in PostgreSQL?
When managing a PostgreSQL database, we may often encounter scenarios where we need to filter data based on date ranges. This could be for generating reports, analyzing trends, or retrieving time–sensitive information. However, querying for data within a specific date range can be a challenging task, especially when dealing with large datasets.
In this article, we will explore three different approaches to selecting dates between two dates in PostgreSQL. Each approach offers its own advantages and use cases, allowing you to choose the method that best suits our specific requirements.
