mySQL引用WHERE子句中的别名（EAV模型）

Question

我有以下mySQL查询，基本上搜索所有包含＆＃39; rawganic＆＃39;在名称中。

它看起来很乱，因为Magento使用的Entity-attribute-value模型非常令人困惑，因此我有很多选择查询来提取数据（我确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%')

结果是：

这很好，除了现在我想添加另一个WHERE子句，其中Type必须是＆＃39; simple＆＃39;状态为＆＃39; 1＆＃39;。

SELECT查询引用别名＆＃39; eID＆＃39;但是我不能在WHERE子句中使用它。如何添加这些额外的WHERE子句？

您可以使用HAVING：

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
