![]() ![]() 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. The timestamp data type is more readable.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. In our example, the text date and time ' 7/15:23:45'was converted to the timestamp value 15:23:45+02. The function TO_TIMESTAMP() returns a timestamptz value with time zone information. Notice that the input format is a string. You can find a complete list of datetime pattern elements in the PostgreSQL documentation. Note that we use slashes (/) as date part delimiters and colons (:) as time part delimiters. ss represents a 2-digit second (from 00 to 59).MI represents a 2-digit minute (from 00 to 59).HH24 represents a 2-digit hour (from 00 to 23).DD represents a 2-digit day of the month.Here are the main elements from the above pattern: The input format indicates how the characters in the string should be converted. This function takes two arguments: a string containing a date and time (in our example, the text ' 7/15:23:45') and the input format (in our example, ‘ YYYY/MM/DD/HH24:MI:ss’). Use the PostgreSQL function TO_TIMESTAMP() when you want to convert a string containing date and time data to the timestamp data type. Here’s the result of the query: new_timestamptz ![]() ![]() Let’s convert a string containing date, time, and time zone information to the timestamptz data type. You’d like to convert a string containing datetime information to a timestamp in PostgreSQL. ![]()
