How can search a column by date format? - mysql

Question

I'm trying to create a query according the day and month at the same time condition between 2 columns in a period of time like this:
Here is the demo
Here is the information:
CREATE TABLE clients
(date_birth date, [date_anniversary] date)
;
INSERT INTO clients
([date_birth], [date_anniversary])
VALUES
('1911-01-04',NULL ),('1921-01-05',NULL ),('1931-01-06',NULL ),('1941-01-07',NULL ),
('1951-01-08',NULL ),('1961-01-09',NULL ),('1971-01-10',NULL ),('1981-01-11',NULL ),
('1991-01-12',NULL ),(NULL, '1998-02-13'),(NULL, '1999-02-14'),(NULL, '2000-02-15'),
(NULL, '2001-02-16'),(NULL, '2002-02-17'),(NULL, '2003-02-18'),(NULL, '2004-02-19'),
(NULL, '2005-02-20'),(NULL, '2006-02-21');
Here is the condition:
since "04-01" until "13-02"
show all from clients where date_birth BETWEEN "04-01" AND "13-02" OR date_anniversary "04-01" AND "13-02"
This should be the output:
('1911-01-04',NULL ),
('1921-01-05',NULL ),
('1931-01-06',NULL ),
('1941-01-07',NULL ),
('1951-01-08',NULL ),
('1961-01-09',NULL ),
('1971-01-10',NULL ),
('1981-01-11',NULL ),
('1991-01-12',NULL ),
(NULL, '1998-02-13'),
I tried this but is just for month:
select date_birth from clients
where month(date_birth) BETWEEN '00' AND '01'
And also tried:
SET #date1 := 01-14;
SET #date2 := 02-20;
select date_birth from clients
where date_birth BETWEEN #date1 AND #date2
Please somebody can help me?

Answer 1

You can do so by using Mysql's month and day functions
SELECT date_birth ,date_anniversary
FROM clients
WHERE
(
MONTH(date_birth) >= 01 AND MONTH(date_birth) <= 01
AND DAY(date_birth) >= 01 AND DAY(date_birth) <= 31
)
OR
(
MONTH(date_anniversary) >= 01 AND MONTH(date_anniversary) <= 01
AND DAY(date_anniversary) >= 01 AND DAY(date_anniversary) <= 31
)
Fiddle Demo
using Mysql's date_format function just format your columns by day and month can compare with the provided range of same format,also provide your parameters as in this '%m-%d' format
select date_birth ,date_anniversary
from clients
where date_format(date_birth,'%m-%d') BETWEEN '01-01' AND '01-31'
or
date_format(date_anniversary,'%m-%d') BETWEEN '01-01' AND '01-31'
Fiddle demo 2
Storing values in variables
SET #start:='01-01';
SET #end:='01-31';
SELECT date_birth ,date_anniversary
FROM clients
WHERE DATE_FORMAT(date_birth,'%m-%d') BETWEEN #start AND #end
OR
DATE_FORMAT(date_anniversary,'%m-%d') BETWEEN #start AND #end

Answer 2

If you are using MySQL try this:
SELECT
date_birth
,date_anniversary
FROM clients
WHERE
DATE_FORMAT(date_birth, '%m-%d') BETWEEN DATE_FORMAT('1900-01-04', '%m-%d') AND DATE_FORMAT('1900-02-13', '%m-%d')
OR DATE_FORMAT(date_anniversary, '%m-%d') BETWEEN DATE_FORMAT('1900-01-04', '%m-%d') AND DATE_FORMAT('1900-02-13', '%m-%d')
If you are using MSSQL e posted into wrong subject try to google a DATE_FORMAT() function equivalent on it.
