Question

Hope someone can tell ..

Table A                  Table E
Id  |  Date              Id  |  Start_date  |  End_date
 1     2012-12-10         1     2012-12-09     2012-12-10
 2     2012-12-11         2     2012-12-12     2012-12-14

The Result that I’m hoping ..
2012-12-11

This is the code that I think might work to select date from Table A that not in Table E ranga date…

SELECT * FROM `A` 
WHERE `A`.`DATE` NOT BETWEEN (SELECT `E`.`DATE_START` FROM `E`) AND (SELECT `E`.`DATE_END`       
FROM `E`);

but unfortunately not, the subquery return more than 1 row.

I wonder how??

thanks

To get all records from A that are not inside any of the date ranges in E, get the records that are within the date ranges, and select the ones not in that result:

select *
from A
where Id not in (
  select A.Id
  from A
  inner join E on A.Date between E.Start_date and E.End_date
)
