I have a column in a SQL database named dogs.  I want to query for all records in that column that are not null then get a record count for each breed of dog.  I have sucessfully queried for all records that are not null but need to know how to pass the results to another query to get the record number for each breed.
Thanks,
Kim

try this,

-assume your first query which get all not null dogs is called yourFirstQuery

<cfloop query="yourFirstQuery">
  -set a variable to yourFirstQuery.dogBreed
  <cfquery name=#yourFirstQuery.dogBreed
#_Query datasource=youDataSource>
    SELECT count(*) FROM dogTable WHERE dogBreed = '#theVariable#'
  </cfquery>
  -now you have counting querys for each breed of dog named for the particular dog
  -#yourFirstQuery.dogBreed#_Query.count should have the number of the breed for the dog in variables.dogBreed
</cfloop>

good luck

Ok, I have it producing the distinct names but the count is coming up as 0 for every record.  I have posted my queries below.  Thanks for your help!
Kim

<cfquery name="GetDepr" datasource="dre_new" dbtype="ODBC">
            Select Distinct(Conf_CNS_Depr_list)
            from dreeval
            Where dreeval.Conf_CNS_Depr_list <> 'none'
            Order by Conf_CNS_Depr_list
</cfquery>
<cfloop query="GetDepr">
      <cfset DeprUsed = "GetDepr.Conf_CNS_Depr_list">
            <cfquery name="GetDeprUsed" datasource="dre_new" dbtype="ODBC">
                  Select count(*) as DeprNum
                  from dreeval
                   where Conf_CNS_Depr_list ='#Variables.DeprUsed#'
            </cfquery>
</cfloop>
<table>
<cfoutput query="GetDepr">
#GetDepr.Conf_CNS_Depr_list# -  #GetDeprUsed.DeprNum#<br>
</cfoutput>
</table>

I found one problem
<cfset DeprUsed = "GetDepr.Conf_CNS_Depr_list">
and changed the code to
<cfset DeprUsed = "#GetDepr.Conf_CNS_Depr_list#">
but now I am getting just one record count for each type.
Thanks,
Kim

Your code only creates one query.  You need to name the query (2nd) something with the particular breed in the title i.e. #DeprUsed#_CountQuery.  That way you get separate and different queries for each breed and can do a similar loop to go through those queries.  Presently your code only creates one query and executes it for each breed.  I would guess that the breed table only has one record of that type.  You're almost there, good luck.
