I need to convert a varchar value of 1/9/2011 to a date in mySQL and I want only the month and year. So that I can then use the PERIOD_DIFF
function (so I would need the above to be converted to 201101).
I've tried various ways using the STR_TO_DATE
function:
SELECT STR_TO_DATE(CYOApp_oilChangedDate, '%m/%Y') FROM CYO_AppInfo
But I get weird results... (for example: 2009-01-00)
What am I doing incorrectly?
This question is related to
mysql
select date_format(str_to_date('31/12/2010', '%d/%m/%Y'), '%Y%m');
or
select date_format(str_to_date('12/31/2011', '%m/%d/%Y'), '%Y%m');
hard to tell from your example
As gratitude to the timely help I got from here - a minor update to above.
$query = "UPDATE `db`.`table` SET `fieldname`= str_to_date( fieldname, '%d/%m/%Y')";
