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.

Answer 1

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.
