sql - MySQL trouble getting value from a third table in query -


i need retrieving value third table

product_attribute | id_product_attribute | id_product | reference | ean13 |  product_attribute_combination | id_attribute | id_product_attribute |  attribute_lang | id_attribute | name |

i did query below product list, want name attribute_lang , don't know how.

can me on this?

this have now

select t1.id_product, t1.reference, t2.name, t1.price, if(length(trim(t1.ean13)) = 0, t1.id_product, t1.ean13) ean13         /*prefix*/product_attribute t1         inner join /*prefix*/product_lang t2 on (t1.id_product = t2.id_product , t2.id_lang = /*current_language_id*/)          t1.id_product /*products_id_list*/

you need add 2 more joins:

left join /*prefix*/product_attribute_combination t3 on t3.id_product_attribute=t1.id_product_attribute left join /*prefix*/attribute_lang t4 on t4.id_attribute=t3.id_attribute

and add t4.name selected column

the result this:

select t1.id_product, t1.reference, t2.name, t1.price, if(length(trim(t1.ean13)) = 0, t1.id_product, t1.ean13) ean13, t4.name /*prefix*/product_attribute t1 inner join /*prefix*/product_lang t2 on (t1.id_product = t2.id_product , t2.id_lang = /*current_language_id*/) left join /*prefix*/product_attribute_combination t3 on t3.id_product_attribute=t1.id_product_attribute left join /*prefix*/attribute_lang t4 on t4.id_attribute=t3.id_attribute t1.id_product /*products_id_list*/
