MySQL display all date in between range [duplicate

问题:

This question already has an answer here:

• generate days from date range 25 answers

I want to display all dates between a from and to dates from MySQL.

For example the data from schedule table that has from and to fields are:

from date is 2013-3-13, and

to date is 2013-3-20,

my desired result is:

 2013-3-13
 2013-3-14
 2013-3-15
 2013-3-16
 2013-3-17
 2013-3-18
 2013-3-19
 2013-3-20

How can I achieve this using MySQL query only (without having to use stored procedure 'cause I'm not familiar with it)?

EDIT:

The answer here is very helpful, though I still don't fully get what is desired. In this sample, it only runs successfully but doesn't output anything. And I don't know what seems to be the problem.

Please help. Thanks!

You can use the following to generate your list of dates:

select a.Date,  s.*
from 
(
  select curdate() + INTERVAL (a.a + (10 * b.a) + (100 * c.a)) DAY as Date
  from (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as a
  cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as b
  cross join (select 0 as a union all select 1 union all select 2 union all select 3 union all select 4 union all select 5 union all select 6 union all select 7 union all select 8 union all select 9) as c
) a
inner join schedule s
  on a.Date >= s.fromDate 
  and a.Date <= s.toDate

try where from date is 2013-3-13, and to date is 2013-3-20,

"SELECT * FROM schedule WHERE Field BETWEEN $fromdate AND $todate";
