The date thus extracted from the specified timestamp by running the query stated above is shown in the image below: Conclusion: Moreover, we have made use of the “d”, “m”, and “y” characters over here just to label these entities of the date in our output for an added level of clarity. Again, you can also use the current timestamp over here. For example, you can get the year first, followed by the month and the day from the given timestamp. However, you do have the liberty to change the output format in which you will get the date after the execution of this query simply by changing the order of this query. These three entities cannot be extracted at once using the “Date_Part” function rather, you will have to run this function thrice within the same query in any case, which is why it is a relatively inefficient way of extracting the date from the given timestamp. This query will run the “Date_Part” function of PostgreSQL thrice to get the day, month, and year from the given timestamp one by one. To make the “Date_Part” function to perform this task, you will have to execute the following PostgreSQL query:
The “Date_Part” function of PostgreSQL can also be used to get the day, month, and year, i.e., the date from the given timestamp. Method # 4: Using the Date_Part Function in PostgreSQL: In the very same manner, you can also extract the year or day from the specified timestamp by making use of the “Extract” function of PostgreSQL simply by replacing the “MONTH” keyword in the arguments with “YEAR” or “DAY” keywords, respectively. Again, the “SELECT” statement will be responsible for displaying the desired output on the console, as shown in the image below: You have the choice to skip this phrase if you wish. Finally, the “as month” phrase will simply label our output for more clarity. Therefore, we have passed the “MONTH” keyword as an argument to the “Extract” function followed by the “TIMESTAMP” keyword, which is proceeded by a random timestamp (you can also use the current timestamp over here if you want). In this query, we wanted to extract the month from the specified timestamp. # SELECT EXTRACT(MONTH FROM TIMESTAMP ‘ 10:25:15’) as month You are simply required to run the following query to visualize this: When it is combined with the “date” keyword with the help of the “::” operator, then it can be used to convert the current timestamp to date. The “Now” function of PostgreSQL can be used to get the current timestamp, i.e., the current date and current time. Method # 1: Using the Now Function in PostgreSQL:
Four of the most commonly used methods of doing so are discussed below, using which you can easily convert any given timestamp to date very quickly. In this regard, PostgreSQL presents us with different ways to convert the given timestamp to date. In such a situation, we might want to truncate the time part from this timestamp while saving only its date part for further execution of queries or simply saving that date. However, we are not concerned with the time part of this timestamp rather, we only require its date part. This value can correspond to the current date and time or any other random date and time.

Ways of Converting the Timestamp to Date in PostgreSQL in Windows 10:īy the word timestamp, we essentially mean the date and time combined.
This article will focus on some of the most efficient methods of converting the given timestamp to a date in PostgreSQL in Windows 10. To facilitate this, PostgreSQL offers us different functions which are capable of converting the given timestamp to a date very easily. However, there are such situations in which we are provided with a timestamp, and we want to convert it to date. At times, these functions are used to convert a given string to a date, and sometimes, they are simply used to get the current system date. By now, we have realized that PostgreSQL provides us with a wide range of functions that can be used with a date.
