mysql - Trying to add a subquery to a join query -

-

i have query this

select     tbl_products.*,     group_concat(tags.name)     tbl_page_collections_products,     (select page_collection_name name         tbl_page_collections         left join tbl_pages on tbl_page_collections.page_id = tbl_pages.page_id         tbl_pages.page_name '%friends%') tags     left join tbl_page_collections        on tbl_page_collections.page_collection_id = tbl_page_collections_products.colid      left join tbl_pages        on tbl_page_collections.page_id = tbl_pages.page_id      left join tbl_products        on tbl_products.product_id = tbl_page_collections_products.product        tbl_pages.page_name '%friends%'

the error unknown column 'tbl_page_collections_products.colid in on clause don't error when subquery isn't there , column exists in table.

is conflicting?

tbl_page_collections_products not in subquery clause. maybe want:

select tbl_products.*, group_concat(tags.name) tbl_products, (select page_collection_name name     tbl_page_collections    ,tbl_page_collections_products    left join tbl_pages on tbl_page_collections.page_id = tbl_pages.page_id     tbl_pages.page_name '%friends%') tags left join tbl_page_collections    on tbl_page_collections.page_collection_id = tbl_page_collections_products.colid  left join tbl_pages    on tbl_page_collections.page_id = tbl_pages.page_id  left join tbl_products    on tbl_products.product_id = tbl_page_collections_products.product  tbl_pages.page_name '%friends%'
