Question

我有一种情况，rearch将返回单个产品SKU，我将返回，例如：

SELECT 
pr.SKU,
pr.pkSKU,
pr.ColorDescription,
pr.CommonBrandName,
pr.BaseModel
FROM tbl_products AS pr WHERE pr.pkSKU = 160386  
ORDER BY pr.CommonBrandName, pr.SKU, pr.StandardColor

但SKU可能有其他替代颜色可供选择，这些颜色通过BaseModel链接，我需要显示这些颜色，我知道我可以通过编写一个新的查询来做到这样：

SELECT 
pr.SKU,
pr.pkSKU,
pr.ColorDescription,
pr.CommonBrandName,
pr.BaseModel
FROM tbl_products AS pr WHERE pr.BaseModel = "result from previous query"  
ORDER BY pr.CommonBrandName, pr.SKU, pr.StandardColor

但我真正想做的是将其合并为一个查询，这可能吗？

其次，如果是，我需要订购结果，以便从第一个查询返回的SKU始终首先列出如下：

搜索SKU
替代颜色
搜索SKU
替代颜色替代颜色
搜索SKU
替代颜色
等

Answer 1

可能是这样的

SELECT 
pr.SKU,
pr.pkSKU,
pr.ColorDescription,
pr.CommonBrandName,
pr.BaseModel
FROM tbl_products pr 
   INNER JOIN tbl_products pr1 ON pr.BaseModel = pr1.BaseModel
WHERE pr2.pkSKU = 160386  
ORDER BY 
   CASE WHEN pr.pkSKU = 160386 THEN 0 ELSE 1 END,
   pr.CommonBrandName, pr.SKU, pr.StandardColor

MySQL - 连接两个查询，第二个查询按第一个结果过滤
