this one helps. I am very new to SQL, and I am using MySQL, and I have a table that holds blogs. In that table, I have a column named "blog_category". I am trying to return DISTINCT values from the blog_category that appear at least (n) times. Example: , You need GROUP BY:
code :
SELECT blog_category 
FROM blog_posts 
GROUP BY blog_category
HAVING COUNT(*) >= 3;

this will help One trick you can use is to replace the word in the original string. Then compare how many characters were lost. Divided by the length of the word, this gives you the total number of occurrences for that word. For example:
code :
SELECT 
    w.word
,   (length(title) - length(replace(title, w.word, ''))) / length(word)
FROM (select 'lollipop lollipop oh la le la le lollipop' as title) t
CROSS JOIN (
    select 'la' as word
    union all select 'le'
    union all select 'lollipop'
    union all select 'shooby'
) w

-->

la          2.0000
le          2.0000
lollipop    3.0000
shooby      0.0000

wish of those help This is kind of a complicated to explain. Their is a part of my site called "Rising Users". The problem is, I can't actually place any users.
code :
SELECT following
    FROM YourTable
    GROUP BY following
    ORDER BY COUNT(*) DESC LIMIT 1;
Is it possible to combine 'DISTINCT' and 'COUNT' queries, so that I can see how many times each distinct value appears?

this one helps. Say that my database was like IMDb, a huge collection of movie titles and their release dates. , Instead of distinct + count it would be group by
code :
 select field, count(*) from table group by field
SELECT DISTINCT 2 columns and count the # of times it appears on either

SELECT DISTINCT 2 columns and count the # of times it appears on either
