Using the NOW() function to get the current date SELECT now() We might need to do this for users from different time zones all over the world. Sometimes, it is critical to alter the date format or calculate the values in the PostgreSQL table. The default value in a DATE column in a Postgres database can be set by using the keyword DEFAULT CURRENT DATE, as in the script below: CREATE TABLE myevents (Įvent_date DATE NOT NULL DEFAULT CURRENT_DATEĪs you can see, a value for the column is automatically inserted by the PostgreSQL server, using the current system date in the format of YYYY-MM-DD. Using the current date as the default value Taking care of code formatting, syntax check, and code completion, the Postgres SQL formatter feature built-in dbForge Studio for PostgreSQL will let you stay focused on dealing with the DATE data type as well. dbForge Studio for PostgreSQL can boast a convenient and intuitive PostgreSQL Formatter.

It is highly important to retain code readability at the stage of writing it. Note that the earliest possible date is 4713 BC and the latest possible date is 5874897 AD. It needs 4 bytes to store a date value in a column.

Using TO_TIMESTAMP() to convert a string to a timestampĭATE data type in PostgreSQL is used to store dates in the YYYY-MM-DD format (e.g.

Using the EXTRACT() function to get the year, quarter, month, week, day from a date value.

Using the AGE() function to get the date difference in years, months, and days.

Using the minus operator to get the interval between two dates.

Using the TO_CHAR() function – output the date value in a specified format.

Using the NOW() function to get the current date.

Using the current date as the default value.

Postgres is capable of handling a wide range of data formats. In addition, you should modify the date format to meet the preferences of your users. The data type and format of the date column should always be consistent with the information entered by the user. The tricky thing about dates is that their formats vary in different countries, so it can be quite a challenging task for beginners in database management. You can use dates and timestamps for data analysis and data storage, as they allow you to determine when an event actually occurred. We will be using dbForge Studio for PostgreSQL to illustrate the examples.

In this article, we will look into working with dates in PostgreSQL, including the various date data types and formats, their functions, and the ways how to deal with them in your everyday routine.
