Converting varchar mm/dd/yy to date format yyyy-mm-dd

Question

I am trying to migrate data from one table to other. The issue is my target table has type date yyyy-mm-dd where as the source table has type varchar mm/dd/yy I tried a few thing but seems none worked.

I am trying this but seems to give null

select year((datecreated)) * 10000 + month((datecreated)) * 100 + day((datecreated)) from employee

Here employee is my table and datecreated is my column.

If someone has come across this please let me know how to fix it.

You can try the STR_TO_DATE to convert a string to a date:

SELECT STR_TO_DATE(datecreated,'%m/%d/%Y') as date
FROM employee

Date format specifications (%m, etc) can be found here .
