Convert varchar column to date in mysql at database level

Question

I have one column date1 which is varchar type I want this column to date type. I tried changing field but all date is converted to 0

Answer 1

use STR_TO_DATE Function of MySQL

FIRST you will need to update the value in date format.

UPDATE `tbl` SET `date1` = STR_TO_DATE(`date1`, '%d-%m-%Y') WHERE 1=1

THEN Convert the field to date.

Most importantly remember to insert date as Y-m-d format, after then.
