ETL: SQL Set column type
![Theresa2000](https://us.v-cdn.net/6032830/uploads/defaultavatar/nZ5X977MOM3Z6.jpg)
Is there a way to set the column type of while you are creating the column in mysql? I have a column that I am creating based on a date (Min Cust Svc Start) and a comparison to another date (1/1/2015). I want "Min Cust Svc Start 15" to be a datetype column; however, it is defaulting to text. I know I can change it in alter tab but am wondering if there is a way to change it in the query below (while I am creating the field)? Also, am looking for guidance on which is the preferred method...
select tc.*,
CASE
WHEN `Min Cust Svc Start` < '2015-01-01' THEN
'2015-01-01'
ELSE `Min Cust Svc Start`
END AS `Min Cust Svc Start 15`
from `transform_cust_svc` tc

Definitely:
CAST(value AS type)
For you that would be like
SELECT
...
CAST(`Min Cust Svc Start` as Date)
...
Depending on what your string data looks like you might have to do some formatting, but the CAST could be the one you want.
Also str_to_date works great. Format as necessary.
STR_TO_DATE(tc.`Min Cust Svc Start, '%d/%m/%Y')
