This article provided an in-depth knowledge of the PostgreSQL CURRENT_TIMESTAMP Function. The output: note_id | message | created_at Third, use the following query to ensure that the insert was properly performed: SELECT VALUES('Testing current_timestamp function') īecause we did not specify a value for the created at column in this statement, it defaulted to the timestamp at which the transaction began. Second, add a new row to the note table as follows: INSERT INTO note(message) The result of the CURRENT TIMESTAMP() function provides the default value for the created at column. CREATE TABLE note(Ĭreated_at TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP The current statement’s start time is the time of the most recent command received from you.įirst, make a table called note with a created at column that is a TIMESTAMP WITH TIME ZONE column. In PostgreSQL, a column’s current timestamp is used as the default value, and the current timestamp and time are used to deliver values with the time zone. The following example showcases the time and timestamp of all three functions. Workflow Examples to Better Understand PostgreSQL TIME_STAMP #Example 1 Notice how after specifying the precision value in brackets with an integer (from 0 to 6) the output obtained is with the desired number of fractional seconds. If you would like to add precision to your query, the query and its output would look like this: SELECT current_timestamp (4) +tz or -tz: the time zone offset (‘+’ or ‘-‘ from UTC).nnnnnn: the number of fractions of a second (This is the precision, from 0-6).The following are the specifications for the above-given format: The output is returned in this format: “YYYY-MM-DD hh:mm:ss.nnnnnn+/-tz” The CURRENT_TIMESTAMP Function returns the output as the current date, time, and time zone offset using the machine’s date, time, and time zone on which PostgreSQL is running.

Yet, they struggle to consolidate the scattered data in their warehouse to build a single source of truth. Now that the difference between the two timestamp options is clear, let’s learn the PostgreSQL CURRENT_TIMESTAMP Function in detail.Īs the ability of businesses to collect data explodes, data teams have a crucial role to play in fueling data-driven decisions. Here’s what a basic LOCALTIMESTAMP query looks like: SELECT LOCALTIMESTAMP Here’s what a basic CURRENT_TIMESTAMP query looks like: SELECT CURRENT_TIMESTAMP PostgreSQL CURRENT_TIMESTAMP vs LOCALTIMESTAMPīoth, CURRENT_TIMESTAMP and LOCALTIMESTAMP, return a timestamp value, with a major difference being, CURRENT_TIMESTAMP returning a value with a TIME ZONE specified. PostgreSQL CURRENT_TIMESTAMP Function: Workflow Examples.PostgreSQL CURRENT_TIMESTAMP Function: Basics.We will also learn about the Precision argument to provide the most precise output. In this tutorial article, we will learn how to use the PostgreSQL CURRENT_TIMESTAMP Function skillfully through some workflow examples. The syntax looks like this: CURRENT_TIMESTAMP(precision) The PostgreSQL Current_Timestamp Function helps you find the same with precision up to 6 decimal places. For instance, you would want the exact time a transaction would have started. By default, the output value only goes up to 6 decimal places.Īn easier way to understand would be through an example. As the name would suggest, the Precision argument results in the time value output with a fractional second accuracy. In addition, the function query also takes in an optional argument, Precision.
