Question

I want to make a query which returns me some values between two dates and two times…

The DATE and TIME values are in different columns, DATE is called FECHA and TIME is called HORAIN

I have 4 possible values with just a DATE query:

Value 1 has Date 2012-05-07 time 02:45:00
Value 2 has Date 2012-05-07 time 12:00:00
Value 3 has Date 2012-05-08 time 04:35:00
Value 4 has Date 2012-05-08 time 07:30:00

What I want to get, is the results from 07:00:00 to 23:59:59 from the first day, and values from 00:00:00 to 06:59:59 from the second day (so an interval from 07 AM to 06:59 AM)

This is my query, which is returning NO VALUES… It must return me VALUE 2 and VALUE 3, because it matches my desired requirements

SELECT * FROM mytable
WHERE
(DATE(fecha)>='2012-05-07' AND TIME(horain)>='07:00:00')
AND
(DATE(fecha)<='2012-05-08' AND TIME(horain)<='06:59:59');

What am I doing wrong? 🙁

Answer 1

You can fetch result using Concat(). It concatenating two fields value.so You can concatenate fecha with horain field value and then search for results like given below .

SELECT *   FROM `mytable` WHERE (Concat(`fecha`, ' ', `horain`, '') <= '2012-05-08 06:59:59') AND (Concat(`fecha`, ' ', `horain`, '') >= '2012-05-07 07:00:00')

Concat() function take 4 parameter.

1. Value1
2. String from which concatenate value1 to value2
3. Value2
4. String want to concatenate in last

Hopefully it will be helpful for you

thanks.
