MySql limiting only first table from joined table

Question

I'm kind of struggling to limit only one table from the joined table.

I want to limit only the first table rosary_group_name. In the code below I limit both tables. Any idea?

$sql = "
    SELECT e.id,
           e.rosary,
           e.group_name,
           e.description,
           u.group_id,
           u.name,
           u.decade,
           u.intention,
           u.datume 
      FROM `rosary_group_name` AS e 
INNER JOIN `rosary_groups` AS u 
        ON e.id = u.group_id 
  ORDER BY e.id DESC $limit;
"; 

the variable $limit sets the number of rows to display from both tables. I want to apply $limit only to the first table.

You can try to use a sub-query for the first table, like

SELECT 
       e.*
       u.group_id,
       u.name,
       u.decade,
       u.intention,
       u.datume 
FROM (SELECT e.id, e.rosary, e.group_name, e.description, FROM `rosary_group_name` AS e $limit) AS e 
INNER JOIN `rosary_groups` AS u 
        ON e.id = u.group_id 
ORDER BY e.id DESC;

(not sure if the syntax is correct, sorry. but I hope you get an idea)

Inner join will give you limited(matched rows) result. You should consider left join in order to get more result from the left side table
