Multiple select queries in WHERE IN statement

I have the following sql query :

SELECT `main_table`.* FROM `prd_brand` AS `main_table`
INNER JOIN 
    (SELECT DISTINCT value from catalog_product_entity_int where row_id in 
        (select row_id from catalog_product_entity_int where attribute_id = 97 and value = 1) , 
        (select row_id from catalog_product_entity_int where attribute_id = 99 and value = 4)) t 
ON main_table.brand_id = t.value

Is that possible to add multiple select queries in the WHERE IN statement.

BTW, when executing the query I have #1248 - Every derived table must have its own alias.

Solution

  • I'm not quite sure what your query is trying to do. But this seems like a simpler way to write the logic:

    SELECT b.* 
FROM `prd_brand` AS b INNER JOIN 
    (SELECT DISTINCT value 
     FROM catalog_product_entity_int 
     WHERE (attribute_id, value) IN ( (97, 1), (99, 4) )
    ) t
    ON b.brand_id = t.value
