I have a data table which has a column(Ex-Date of Joining) with the data like 07-04-2019 19:30:00(dd-MM-yyyy hh:mm:ss). I want to changes this 07-04-2019 19:30:00 format to 07-04-2019 (dd-MM-yyyy) for a whole column in the data table. I don’t want to use for each row activity because it contains 4000+ records. it takes more time. i want to do this efficiently. please help me to resolve this issue.
