Left join returns blank page 10 Years, 12 Months ago

Karma: 0

This works fine:
{arisqltable}
{arisqltablecolumns}
{arisqltablecolumn id="name"}
{arisqltablecolumn id="email"}
{/arisqltablecolumns}
{arisqltablequery}
SELECT name, email FROM j25_users
{/arisqltablequery}
{/arisqltable}

And this works in phpMyAdmin:
SELECT name, email
FROM j25_users
LEFT JOIN j25_user_usergroup_map
ON j25_user_usergroup_map.user_id = id
WHERE name like '%John%'

But I cannot get this LEFT-JOIN to work:
{arisqltable}
{arisqltablecolumns}
{arisqltablecolumn id="name"}
{arisqltablecolumn id="email"}
{/arisqltablecolumns}
{arisqltablequery}
SELECT name, email
FROM j25_users
LEFT JOIN j25_user_usergroup_map
ON j25_user_usergroup_map.user_id = id
WHERE name like '%John%'
{/arisqltablequery}
{/arisqltable}

Any suggestions? TIA
John

Hello,

Try the following SQL query:

Code:



SELECT 

  name, 

  email

FROM 

  #__users U LEFT JOIN #__user_usergroup_map M

    ON M.user_id = U.id

WHERE 

  U.name LIKE '%John%'

Regards,
ARI Soft

Thanks for the prompt reply, but no luck with that one.

Could you provide a link to a page where we can see the problem and a temporary access to your J! backend by email so we can investigate the problem? Regards, ARI Soft

Thank you for your excellent support.

Here is the code you provided me that worked:

Code:



{arisqltable saveTags="false"}



{arisqltablequery}SELECT U.name, U.email FROM #__users U LEFT JOIN #__user_usergroup_map M ON M.user_id = U.id WHERE U.name LIKE '%John%'{/arisqltablequery}



{/arisqltable}
