How to extract Sphinx group by numbers from result set?

I need some help on Sphinx MySql index group by.

I have a product table where I have product ids and corresponding retailer ids. What I want to do is to create a simple list to show the retailers' names along with how many products it has in the table:

standard SQL: select retailerid, count(productid)as cnt from tblproducts Sphinxs: select * from tblproducts1 group by retailerid

I am using Sphinx 2.0.1-beta

The reason I want to use Sphinx is, because the number of products will be filtered by a complex match full text query, on product name and description etc.

Now my question is, how do I get these numbers/ids from the result returned by Sphinx? As I am using php to display results, I would like if somebody can show me some useful php code to extract these numbers from the result set. The result array returned by Sphinx is confusing me even more; I do not see any reference to the product count anywhere!

I am sure that Sphinx returns these numbers as it supports group by and count, but how do I extract the numbers from the result set?

Below is from my config file:

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_uin开发者_如何转开发t       = MerchantActive
sql_attr_float      = ProductPrice
sql_attr_float      = ProductPrePrice
sql_group_column    = MerchantId

sql_query_info      = SELECT * FROM tblproducts WHERE ProductId=$id

UPDATE

I would expect so, but I don't see the reference to count in the below resultset. I must be making some mistakes somewhere:

There is a magic attribute @count that added to your result set for that query

select * from tblproducts1 group by retailerid

The attribute list in result set looks like

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

In case you use compat_sphinxql_magic=0 option in searchd section you have explicitly define and alias all needed attributes like

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

The attribute list in result set would look like

id, MerchantActive, ... w, c
