我有点像一个MySQL菜鸟，一直试图从Magento中提取产品列表和多个属性。我目前有以下查询，它提取属性185和180.但是，这些是在单独的行中输出。我想编辑查询，以便每个产品的属性都在一行上。我的疑问是：
SELECT
ce.sku AS sku,
ce_decimal.value AS attribute1,
ce_int.value AS attribute2
FROM catalog_product_entity AS ce
LEFT JOIN eav_attribute AS ea
ON ce.entity_type_id = ea.entity_type_id
LEFT JOIN catalog_product_entity_decimal AS ce_decimal
ON ce.entity_id = ce_decimal.entity_id
AND ea.attribute_id = ce_decimal.attribute_id
AND ea.backend_type = 'decimal'
LEFT JOIN catalog_product_entity_int AS ce_int
ON ce.entity_id = ce_int.entity_id
AND ea.attribute_id = ce_int.attribute_id
AND ea.backend_type = 'int'
WHERE ce_decimal.attribute_id = '185'
OR ce_int.attribute_id = '180'
得出以下结果：
_______________________________________
sku attribute1 attribute2
_______________________________________
543 NULL 105
543 34.95 NULL
768 NULL 104
768 15.67 NULL
_______________________________________
我正在寻找的结果是：
_______________________________________
sku attribute1 attribute2
_______________________________________
543 34.95 105
768 15.67 104
_______________________________________
我是否需要使用GROUP_CONCAT或类似的东西？这让我发疯了......谢谢！
答案 0 :(得分：0)
你可以用%lld压缩它：
GROUP BY如果每个sku有多个值，请使用SELECT sku,
MAX(attribute1) AS attribute1,
MAX(attribute2) AS attribute2
FROM (
SELECT
ce.sku AS sku,
ce_decimal.value AS attribute1,
ce_int.value AS attribute2
FROM catalog_product_entity AS ce
LEFT JOIN eav_attribute AS ea
ON ce.entity_type_id = ea.entity_type_id
LEFT JOIN catalog_product_entity_decimal AS ce_decimal
ON ce.entity_id = ce_decimal.entity_id
AND ea.attribute_id = ce_decimal.attribute_id
AND ea.backend_type = 'decimal'
LEFT JOIN catalog_product_entity_int AS ce_int
ON ce.entity_id = ce_int.entity_id
AND ea.attribute_id = ce_int.attribute_id
AND ea.backend_type = 'int'
WHERE ce_decimal.attribute_id = '185'
OR ce_int.attribute_id = '180'
) AS sub
GROUP BY sku;
：
GROUP_CONCAT
