what is wrong with this query?(sql convert date) - mysql

Question

The following query is working perfectly :
SELECT *
FROM MsUser
WHERE absensi_tanggal = DATE_FORMAT( STR_TO_DATE( "' .$query_array['datepicker'] . '", \'%m/%d/%Y\' ) , \'%Y-%m-%d\' )
However, this query is not working. I should miss something there :
SELECT *
FROM MsUser
WHERE absensi_tanggal BETWEEN DATE_FORMAT( STR_TO_DATE( "' .$query_array['datepicker1'] . '", \'%m/%d/%Y\' ) , \'%Y-%m-%d\' )
AND DATE_FORMAT( STR_TO_DATE( "' .$query_array['datepicker2'] . '", \'%m/%d/%Y\' ) , \'%Y-%m-%d\' )
The query above always return 0 result.
Any help is appreciated, Thanks :D

Answer 1

Since STR_TO_DATE returns a proper DATE type value that can be used with BETWEEN, have you tried simply:
SELECT *
FROM MsUser
WHERE absensi_tanggal
BETWEEN
STR_TO_DATE( "' .$query_array['datepicker1'] . '", \'%m/%d/%Y\' )
AND
STR_TO_DATE( "' .$query_array['datepicker2'] . '", \'%m/%d/%Y\' )
My guess would be that MySQL is choking on converting front a string to a date and then back to a string and then back again to a date to make the BETWEEN work.
Also, try this to make it a bit tidier:
"
SELECT *
FROM MsUser
WHERE absensi_tanggal
BETWEEN
STR_TO_DATE('{$query_array['datepicker1']}','%m/%d/%Y')
AND
STR_TO_DATE('{$query_array['datepicker2']}','%m/%d/%Y');
"
And just in case you aren't confirming that the value of datepicker1 is earlier than datepicker2, you can run the query like this to be sure (though I advise only for testing):
SELECT *
FROM MsUser
WHERE
(
absensi_tanggal
BETWEEN
STR_TO_DATE('{$query_array['datepicker1']}','%m/%d/%Y')
AND
STR_TO_DATE('{$query_array['datepicker2']}','%m/%d/%Y')
) OR (
absensi_tanggal
BETWEEN
STR_TO_DATE('{$query_array['datepicker2']}','%m/%d/%Y')
AND
STR_TO_DATE('{$query_array['datepicker1']}','%m/%d/%Y')
);
