I have a sql table like this one:

id  email           links
1   test1@test.com  www.link1.com
2   test2@test.com  www.link2.com
3   test3@test.com  www.link3.com
4   test1@test.com  www.link4.com
5   test2@test.com  www.link5.com
6   test2@test.com  www.link6.com
7   test4@test.com  www.link7.com
8   test5@test.com  www.link8.com
9   test6@test.com  www.llink9.com
10  test2@test.com  www.link10.com

And I need to find a query that will give this kind of result:

email                link1          link2          link3          link4
test1@zendata.ca     www.link1.com  www.link4.com
test2@zendata.ca     www.link2.com  www.link5.com  www.link6.com  www.link10.com
test3@zendata.ca     www.link3.com
test4@zendata.ca     www.link7.com
test5@zendata.ca     www.link8.com
test6@zendata.ca     www.llink9.com

Unique emails with each of the associated links…

Thank you if you can solve this problem,

    This is much more easily done with GROUP_CONCAT() and then processed in application code to split up the resultant string:

    SELECT email, GROUP_CONCAT(links) AS link_list FROM tbl GROUP BY email

    Example results:

    email                link_list
--------------------------------------
test1@zendata.ca     www.link1.com,www.link4.com
test2@zendata.ca     www.link2.com,www.link5.com,www.link6.com,www.link10.com

    This assumes, of course, that you will be processing this result set with some application code in some other programming language.
