mySQL引用WHERE子句中的別名（EAV模型）

Question

我有以下mySQL查詢，基本上搜索名稱中包含'rawganic'的所有產品。

它看起來很混亂，因爲Magento使用的Entity-attribute-value模型很混亂，所以我有很多選擇查詢來拉取數據（我確信可能有更好的方法）。

SELECT entity_id As eID, value as PName, 
    (SELECT value from catalog_product_entity_varchar WHERE attribute_id = 152 and entity_id = eID) as Size, 
    (SELECT sku from catalog_product_entity WHERE entity_id = eID) as SKU, 
    (SELECT type_id from catalog_product_entity WHERE entity_id = eID) as Type, 
    (SELECT value from catalog_product_entity_decimal WHERE attribute_id = 75 and entity_id = eID) as RRP, 
    (SELECT value from catalog_product_entity_int WHERE attribute_id = 96 and entity_id = eID) as Status 
FROM catalog_product_entity_varchar 
WHERE (attribute_id = 71 and value like '%rawganic%') 

結果是：

這是偉大的，但現在我想添加其他WHERE子句，其中的類型必須是「簡單」，狀態爲「1」。

SELECT查詢引用別名'eID'，但是我不能在WHERE子句中使用它。我如何添加這些額外的WHERE子句？

您可以使用具有：

SELECT entity_id As eID, value as PName, 
    (SELECT value from catalog_product_entity_varchar WHERE attribute_id = 152 and entity_id = eID) as Size, 
    (SELECT sku from catalog_product_entity WHERE entity_id = eID) as SKU, 
    (SELECT type_id from catalog_product_entity WHERE entity_id = eID) as Type, 
    (SELECT value from catalog_product_entity_decimal WHERE attribute_id = 75 and entity_id = eID) as RRP, 
    (SELECT value from catalog_product_entity_int WHERE attribute_id = 96 and entity_id = eID) as Status 
FROM catalog_product_entity_varchar 
WHERE (attribute_id = 71 and value like '%rawganic%') 
HAVING Type = 'Simple' AND Status = 1
