duplicates in each multiple categories
as they are different for each record ,
like one product has one database but
multiple platforms ,but I don't want
to print duplicates .

This is an answer:

<cfquery name="A">
      SELECT field1, field2      
        FROM Table      
        GROUP BY field1, field2
      HAVING id=#id#
</cfquery>      

<table border="1">
<cfoutput query="A" group="field1">
<tr>
    <td>#field1#</td>
    <td>&nbsp;</td>
</tr>
      <cfoutput group="field2">
      <tr>
              <td>&nbsp;</td>
            <td>#field2#</td>
      </cfoutput>
</cfoutput>
</table>

There is a posiibility that table
has other fields .

I give you a example

Table View
Product Database Competitor Platform
A        D1       C1        P1
A        D1       C2        P2
A        D2       C1        P1
B        D1       C1        P1
B        D2       C1        P1
B        D3       C3        P3
A        D1                 P1
A        D1       C1  
       
Now I want to select only one product
Let say A ,and I want result as

Product A
Database D1
         D2
Product  P1
         P2
Comp     C1
         C2

Now tell me pls how to do this?

<cfset id='A'>

<cfquery name="Q1">
   SELECT DISTINCT Database
   FROM Table
   WHERE Product = #id#
</cfquery>

<cfquery name="Q2">
   SELECT DISTINCT Competitor
   FROM Table
   WHERE Product = #id#
</cfquery>

<cfquery name="Q3">
   SELECT DISTINCT Platform
   FROM Table
   WHERE Product = #id#
</cfquery>

Product: <cfoutput>#ID#</cfoutput>
<br>

Database:
<cfoutput query=Q1>
   #Database#<br>
</cfoutput>
<br>

Product:
<cfoutput query=Q1>
  #Product#<br>
</cfoutput>
<br>

Competitor:
<cfoutput query=Q1>
  #Competitor#<br>
</cfoutput>
