mySQL 引用 WHERE 子句中的别名（EAV 模型）

Question

我有以下 mySQL 查询，基本上搜索名称中包含 'rawganic' 的所有产品。

它看起来很乱，因为 Magento 使用实体-属性-值模型，这非常令人困惑，所以我有很多 select 查询来提取数据（我相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，其中类型必须是 'simple' 并且状态是“1”。

SELECT 查询引用别名 'eID' 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？

Answer 1

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
