mySQL convert varchar to date
- by Jeff V
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?
