How do I multiple select in mysql using one query?
Select Id,Name From table where id = var
Select Id,Name From table where id = var
Select Id,Name From table where id = var

SELECT  (
    SELECT COUNT(*)
    FROM   user_table
    ) AS tot_user,
    (
    SELECT COUNT(*)
    FROM   cat_table
    ) AS tot_cat,
    (
    SELECT COUNT(*)
    FROM   course_table
    ) AS tot_course

SELECT user_table.name, user_table.email, cat_table.title
FROM user_table
FULL JOIN cat_table
ON user_table.cat_id=cat_table.id
ORDER BY user_table.id
