We hope that this EDUCBA information on “PostgreSQL CURRENT_TIMESTAMP()” was beneficial to you. INSERT INTO STUDENT (stud_id, stud_address, stud_name) VALUES (2, 'Mumbai', 'PQR') It will take the automatic value as the current timestamp at the time of insertion as follows.Ĭode: INSERT INTO STUDENT (stud_id, stud_address, stud_name) VALUES (1, 'Pune', 'ABC') In the below example, we have created the default current timestamp on the admission_date column.Ĭode: CREATE TABLE student (stud_id serial PRIMARY KEY, stud_address varchar(255) NOT NULL, stud_name varchar(255) NOT NULL, admission_date TIMESTAMP WITH TIME ZONE DEFAULT CURRENT_TIMESTAMP) Īfter creating the student table, we do not need to insert a value in the column name as admission_date. In the below example, we have used the current timestamp as the default value in the student table. Use the current timestamp in the column as the default value: We did not use () because we have not defined the precision value in the example below. In the below example, we have not used precision value with the current timestamp. We have used five fractional seconds to define the current timestamp.Ĭurrent timestamp without using precision value: In the below example, we have used a precision value of 5 with the current timestamp. The below example shows that we do not need to use () when we have not used the precision parameter: If we have used () without a precision parameter, it will show a syntax error. We have not need to use () in the current timestamp function when we have not used the precision parameter.TZ – It is defined as the time zone in the current timestamp function.SS – It is defined as the current second in two digits.MM – It is defined as the current minute in two digits.HH – It is defined as the current hour in two digits.DD – It is defined as today’s date in two digits.MM – It defines the month in two digits.YYYY – It is defined as the year in four-digit.The below example shows the format of the current timestamp function in PostgreSQL:Įxplanation: In the above example, the current timestamp format is below. This eliminates the need to manually insert the current timestamp value in every insert statement, as the current timestamp function will automatically populate the column with the current date and time in a specified format. In PostgreSQL, we can assign the default value of the current timestamp to a column using the “default” keyword during table creation. The current timestamp is useful and important in PostgreSQL to return the date and timestamp with the time zone. The start time of the current statement is the time of the latest command received from the client. The current timestamp and the current time are to deliver the values with the time zone in PostgreSQL. ![]() The current timestamp is used as the default timestamp value of a column in PostgreSQL. The below example shows that now, the current timestamp and transaction timestamp function work similarly to each other: Example #1Įxplanation: The above example shows the time and timestamp of all three functions working is the same. ![]() But the transaction timestamp will reflect the same, which the function returned.Įxamples to Implement PostgreSQL CURRENT_TIMESTAMP() Transaction timestamp and the current timestamp is equivalent to each other in PostgreSQL.The current timestamp and now function is similar to work in PostgreSQL. ![]()
