In order to get milliseconds from Timestamp in postgresql we use Extract Keyword. Within the Extract keyword we have to mention MILLISECONDS as we are getting MILLISECONDS from timestamp.
Let’s see how to
- Extract milliseconds from Timestamp in Postgresql
- Create the column which extracts milliseconds from timestamp column
With an example for both
Extract milliseconds from Timestamp in Postgresql:
Within the Extract keyword we have to mention MILLISECONDS as we are getting milliseconds from timestamp
SELECT EXTRACT (MILLISECONDS FROM TIMESTAMP '2011-11-22 13:30:15.203')
So the resultant MILLISECONDS will be
EXTRACT milliseconds from Timestamp in column of Postgresql table:
We use table student_detail
Create the column which extracts MILLISECONDS from timestamp column in Postgresql:
We have created a column and stored milliseconds from Birthdaytime column
SELECT *,EXTRACT (MILLISECONDS FROM Birthdaytime) AS MILLISECONDS FROM Student_detail
So the resultant table will be
