Get a date range in 24 hour format in mysql

Question

I want to know is this query part is correct or not:

DATE_FORMAT(@co, '%Y-%m-%d %T') between '2014-03-24 13:00:00' and '2014-03-25 00:00:00'

because I'm getting wrong output from this query. Can anyone can tell what is wrong with it ?

Here @co is a string value which I want to convert as a 24hr date format.

Answer 1

Whether results are correct depend on what @co contains. But, as its name suggests, DATE_FORMAT() expects a date , not a string.

You should note that MySQL can handle dates as any other data type—you don't need to convert them to strings.
