how to remove key constraint of column in mysql?
ALTER TABLE `table` MODIFY `id` INT ;
ALTER TABLE `table` DROP PRIMARY KEY;MySQL date format DD/MM/YYYY select query?
You can use STR_TO_DATE() to convert your strings to MySQL date values and ORDER BY the result: ORDER BY STR_TO_DATE(datestring, '%d/%m/%Y') However, you would be wise to convert the column to the DATE data type instead of using strings.
