I have a column in a MySQL table where dates are stored as a mm/dd/yyyy string. I need to preserve that column as is, so I have added a new column where I want to store that date as a timestamp. What would the query look like to take column a and convert it to a timestamp and put it into the new column b?
you can use STR_TO_DATE to convert your string like
select str_to_date('02/22/2013','%m/%d/%Y');
UPDATE YourTable set newCol = str_to_date(yourOldCol,'%m/%d/%Y');

This format in database:
Display date some like this:
Below I have mysql query
$sql = "INSERT INTO payment (user_id, course_id, amount, data_added)
SELECT user_id,course_id,monthly_subscription_fee,here_i_need_get_current_time
FROM enrol
WHERE active_shop='1'";
Can anyone help me how can I generate current time in the same format as above screen in position here_i_need_get_current_time
Use:
SELECT DATE_FORMAT(FROM_UNIXTIME(1642633200),'%a,%d-%b-%Y');
Replace 1642633200 with your column name date_added
First you need to convert your date using FROM_UNIXTIME and then give your desired format using DATE_FORMAT
Result:
DATE_FORMAT(FROM_UNIXTIME(1642633200),'%a,%d-%b-%Y')

I am trying to return a value that is a sum of decimal value in SQL Server 2008. I've tried using convert but it doesn't help. Here is the relevant code snips:
#ActivitySum dec (18,2) OUTPUT)
AS
SELECT
#DistinctActivities = COUNT(DISTINCT [Activities].[Activity ID]),
#Activities = COUNT([Activities].[Performer Activity ID]),
#ActivitySum = SUM(Activities.[Score])
FROM
Scenes
INNER JOIN
Every time I execute, if the sum of score has value after the decimal point, the value gets rounded to a whole number.
Any thoughts or solutions?

I am trying to show the dates in (YYYY-MM-DD) format which is stored in (DD-MM-YYYY) format in the table.
Also please explain how to use year() function on (DD-MM-YYYY) date format.
assuming your data type is a string then you could use
for format(DD-MM-YYYY)
select year(str_to_date(yourcol, '%d-%m-%Y'))
or for format (YYYY-MM-DD)
select year(str_to_date(yourcol, '%Y-%m-%d'))

I have a query of 15 columns and one of them has a hexadecimal value, i wanted to convert it to decimal or int. How can i do it
You can also use
SELECT CONVERT(INT, *rowName*) AS Converted *rowName*;
EDIT:
CONVERT works with MS SQL
CONV(num, base, to) is for MySQL
SELECT CONV(*rowName*,16,10) AS Converted *rowName*;
use CONV()
CONV(num , from_base , to_base );
select SELECT CONV('b',16,10)'Hexadecimal to Decimal'

I need convert this integer "1469416462" to datetime in format dd-mm-yyyy hh:mm:ss . Any ideas?
My Intent:
select CONVERT (datetime,1469416462)
The value 1469416462 looks like a Unix-Timestamp.
Unix-Timestamp: Seconds since 1.1.1970
So the solution would be easy like:
For MySQL:
SELECT from_unixtime(1469416462)
