translating sql sub query to join - sql

Question

I had a long query, I short it out by using joins instead and resultant query is as below but still it has sub query. How to convert this sub query to join
SELECT
pav.post_id as Id, img.path as Path, attr.name as Name, pc.title as Category, pav.value_text as Valuess, post.created_on as createdOn
FROM
postings post inner join post_attributes_values pav on post.post_id = pav.post_id
left outer join images img on post.post_id = img.post_id and img.sequence='1'
inner join attributes attr on pav.attr_id = attr.attr_id
inner join categories_parent_categories pc on attr.cat_id = pc.category_id
where
pav.post_id in (select distinct post_id from post_attributes_values where value_text = 'SFX')

Answer 1

After reading your last comment to Matei's answer I have come to realize that you actually want ALL the posts where one of the attributes has value of 'SFX'. If I understood correctly, your only alternative is to add derived table and join by post_id:
SELECT pav.post_id AS Id,
img.path AS Path,
attr.name AS Name,
pc.title AS Category,
pav.value_text AS Valuess,
post.created_on AS createdOn
FROM postings post
INNER JOIN post_attributes_values pav
ON post.post_id = pav.post_id
LEFT OUTER JOIN images img
ON post.post_id = img.post_id
AND img.sequence = '1'
INNER JOIN attributes attr
ON pav.attr_id = attr.attr_id
INNER JOIN categories_parent_categories pc
ON attr.cat_id = pc.category_id
INNER JOIN
(
SELECT DISTINCT post_id
FROM post_attributes_values
WHERE value_text = 'SFX'
) sfxPosts
ON pav.post_id = sfxPosts.post_id
(Query reformatted thanks to instant sql formatter.)

Maybe this? Please test it
SELECT
pav.post_id as Id, img.path as Path, attr.name as Name, pc.title as Category, pav.value_text as Valuess, post.created_on as createdOn
FROM
postings post
inner join post_attributes_values pav on post.post_id = pav.post_id AND pav.value_text = 'SFX'
left outer join images img on post.post_id = img.post_id and img.sequence='1'
inner join attributes attr on pav.attr_id = attr.attr_id
inner join categories_parent_categories pc on attr.cat_id = pc.category_id
