Question

I have a MySQL table (A) and I would like the end result to look like (B). Does anyone know how I can accomplish this task?? I’m guessing a loop/stored procedure, but I’m not sure and I’m fairly new to loops and stored procedures.

(A)
Name    str_date        end_date
Lorenzo 2010-10-09  2010-10-11
Karen   2010-09-10  2010-09-10
Mike    2010-06-01  2010-06-03

(B)
Name     Date
Lorenzo  2010-10-09
Lorenzo  2010-10-10
Lorenzo  2010-10-11
Karen    2010-09-10
Mike     2010-06-01

Answer 1

dont even try to do this in mysql, use your server side programming language to format data.

and if you really, really, really want to:
create a table with all dates needed (i.e. since 1970-01-01 to 2030-01-01) and do something like (untested):

 -- ddl 
 CREATE TABLE all_dates ( date DATE, PRIMARY KEY (date) );

 -- query
 SELECT ad.date, A.Name
 FROM all_dates ad
 JOIN A ON A.str_date <= ad.date AND A.end_date >= ad.date

but still its server side task, not db.
