Question

我需要一些关于Sphinx MySql索引组的帮助。

我有一个产品表，其中有产品ID和相应的零售商ID。我想要做的是创建一个简单的列表，以显示零售商的名称以及它在表中的产品数量：

标准SQL：从tblproducts中选择retailerid，count（productid）作为cnt 狮身人面像：通过retailerid

从tblproducts1组中选择*

我正在使用Sphinx 2.0.1-beta

我想使用Sphinx的原因是，因为产品数量将通过复杂的匹配全文查询，产品名称和描述等进行过滤。

现在我的问题是，如何从Sphinx返回的结果中获取这些数字/ ID？因为我使用php来显示结果，我想如果有人可以向我展示一些有用的PHP代码来从结果集中提取这些数字。 Sphinx返回的结果数组让我更加困惑;我在任何地方都没有看到任何产品数量的参考！

我确信Sphinx会返回这些数字，因为它支持group by和count，但是如何从结果集中提取数字呢？

以下是我的配置文件：

sql_query       = \
    SELECT ProductId, ProductName, ProductModel, ProductDesc, ProductManf, ProductHeader, \
    ProductPrice, ProductPrePrice, ProductFetchDate, m.MerchantId, m.MerchantActive FROM tblproducts p \
    inner join tblmerchantlist m on p.MerchantId=m.MerchantId


sql_attr_uint       = MerchantActive
sql_attr_float      = ProductPrice
sql_attr_float      = ProductPrePrice
sql_group_column    = MerchantId

sql_query_info      = SELECT * FROM tblproducts WHERE ProductId=$id

更新

我希望如此，但我没有看到在下面的结果集中计数的引用。我必须在某处犯错：

有一个魔术属性@count已添加到该查询的结果集

select * from tblproducts1 group by retailerid

结果集中的属性列表类似于

id, weight, MerchantActive, ... @groupby, @count

如果您在searchd部分中使用compat_sphinxql_magic = 0选项，则您已明确定义和别名所有需要的属性，如

select *, weight(*) as w, count(*) as c from tblproducts1 group by retailerid

结果集中的属性列表看起来像

id, MerchantActive, ... w, c

如何从结果集中的数字中提取Sphinx组？
