How to combine this SQL query? - mysql

Question

i have this query that it works ok but doesn't retrieve exact information (firstname,lastname), it only gives second name
SELECT b.email, c.value AS firstname, a.updated_at, d.added_at
FROM `wishlist` AS a
INNER JOIN customer_entity AS b
ON a.customer_id = b.entity_id
INNER JOIN customer_entity_varchar AS c
ON a.customer_id = c.entity_id
AND c.attribute_id = (
SELECT attribute_id
FROM eav_attribute
WHERE attribute_code = 'lastname'
AND entity_type_id = b.entity_type_id )
INNER JOIN wishlist_item AS d
ON a.wishlist_id = d.wishlist_id
INNER JOIN catalog_product_entity AS e
ON d.product_id = e.entity_id
LEFT JOIN sales_flat_order AS f ON
f.customer_email = b.email
LEFT JOIN sales_flat_order_item AS g
ON ( f.entity_id = g.order_id
AND g.sku LIKE CONCAT( e.sku, '%' )
AND g.product_type = 'simple' )
WHERE d.added_at
BETWEEN '2015-01-01'
AND '2015-02-01'
GROUP BY b.email
This query if i execute will result all customers fullname correctly
SELECT entity_id, group_concat(VALUE SEPARATOR ' ') AS fullname
FROM customer_address_entity_varchar AS val
INNER JOIN eav_attribute AS attr
ON attr.attribute_id = val.attribute_id
WHERE attr.attribute_code IN ( 'firstname', 'lastname' )
How can i edit the 1st query part of retrieving the customer name as the example on the 2nd query?
I am a little bit confused , i tried many combination in sql but non of them will work.
EDIT: i have updated the 1st long query, price should not be there. Also i understand that the group makes no sense but i need only 1 row per customer so i will have to hide the products. If possible all the products to be like wishproduct_1,wishproduct2,wishproduct3 .. in the same row be awesome.

Try this:
SELECT b.email,
h.price as firstname,
c.price AS lastname,
a.updated_at,
d.added_at
FROM `wishlist` AS a
INNER JOIN customer_entity AS b
ON a.customer_id = b.entity_id
INNER JOIN customer_entity_varchar AS c
ON a.customer_id = c.entity_id
AND c.attribute_id =
(
SELECT attribute_id
FROM eav_attribute
WHERE attribute_code = 'lastname'
AND entity_type_id = b.entity_type_id
)
INNER JOIN customer_entity_varchar AS h
ON a.customer_id = c.entity_id
AND c.attribute_id =
(
SELECT attribute_id
FROM eav_attribute
WHERE attribute_code = 'firstname'
AND entity_type_id = b.entity_type_id
)
INNER JOIN wishlist_item AS d
ON a.wishlist_id = d.wishlist_id
INNER JOIN catalog_product_entity AS e
ON d.product_id = e.entity_id
LEFT JOIN sales_flat_order AS f
ON f.customer_email = b.email
LEFT JOIN sales_flat_order_item AS g
ON ( f.entity_id = g.order_id
AND g.sku LIKE CONCAT( e.sku, '%' )
AND g.product_type = 'simple' )
WHERE d.added_at
BETWEEN '2015-01-01' AND '2015-02-01'
GROUP BY b.email, h.price, c.price, a.updated_at, d.added_at
LIMIT 0 , 30
I assumed that the field containing the actual first name would be the same as the one containing the last name (although price seems to be an odd choice). Also since I used correct grouping, you may notice that you will get more records. In that case one or more of teh fields in the group by need to be changed to an aggregate function such as Max() or Min() in order to have one record per email. Your business rules would need to dictate which aggregate function you would apply though.
