Mysql query between 3 date ranges

I have a PHP script that allows the user to create reports, they have the option to select 3 date ranges. i.e.

2012-01-01 to 2012-01-31
AND 
2011-01-01 to 2011-01-31
AND 
2010-01-01 to 2010-01-31

      

But when I execute my query and there are no records between the specified date range, the query does not return any values.

Here is my request:

 SELECT DealerName WHERE InterviewDate >= "2012/01/01 " AND InterviewDate <= " 2012/03/31"
 AND InterviewDate >= "2012/07/01 " AND InterviewDate <= " 2012/09/31"

      

I need a query that will return data if it is found in 1 of the date ranges, regardless of whether there is data in subsequent date ranges.

The data is summarized into a table in which one could have the same data on several dates.

eg:

dealerName 1    2012-01-01
dealerName 1    2012-02-31
dealerName 2    2012-03-01
dealerName 1    2012-06-01
dealerName 1    2012-06-31

      

So, if I wanted to query data between 2012-01-01 and 2012-02-31 AND 2012-06-01 AND 2012-06-31. I understand that 1 date range can span all of these ranges, but the user might want to exclude data between these two date ranges.

The interview date cannot be between x and y AND is still between z and zz. You are missing OR

- Also look at the operatorBETWEEN

SELECT DealerName
FROM table
WHERE InterviewDate BETWEEN '2012-01-01' AND '2012-01-31'
    OR InterviewDate BETWEEN '2011-01-01' AND '2011-01-31'
    OR InterviewDate BETWEEN '2010-01-01' AND '2010-01-31'

      



edit, sorry, missed the table name :)

You need to use OR

insteadAND

WHERE   (InterviewDate BETWEEN '2012-01-01' AND '2012-01-31')
        OR
        (InterviewDate BETWEEN '2011-01-01' AND '2011-01-31')
        OR
        (InterviewDate BETWEEN '2010-01-01' AND '2010-01-31')

      

UPDATE 1



I think you have a problem Relational Division

,

SELECT name
FROM   table1
WHERE  DATE BETWEEN '2012-01-01' AND '2012-02-31'
       OR
       DATE BETWEEN '2012-06-01' AND '2012-06-31'
GROUP BY name
HAVING COUNT(*) = 2

Why not use OR instead of AND?

SELECT DealerName WHERE ( InterviewDate >= "2012/01/01 " AND InterviewDate <= " 2012/03/31" )  OR ( InterviewDate >= "2012/07/01 " AND InterviewDate <= " 2012/09/31" )

Use OR

insteadAND

SELECT DealerName FROM tbl
WHERE InterviewDate >= '2012/01/01' AND InterviewDate <= '2012/03/31'
 OR InterviewDate >= '2012/07/01' AND InterviewDate <= '2012/09/31'

Here is my fence :) since you are checking month

January for year

2010, 2011, 2012. We can use month

and year

.

SELECT DealerName
FROM yourtable
WHERE Month(InterviewDate) = 1
AND Year(InterviewDate) IN (2010, 2011, 2012)
;

SELECT DealerName
FROM yourtable
WHERE Month(InterviewDate) IN (1, 2) // if there are particular months
AND Year(InterviewDate) IN (2010, 2011, 2012)
;
