Question

How to print all the result without using Results.columnname in ColdFusion

for ex:-

I have <cfquery name="getProductId">
select productId
from product
</cfquery>

In Product Table i have 2 columns with product_name and Product_id.

How can I print them without using
getProductId.product_name
getProductId.Product_id

Thanks,

What are you trying to achieve? If you are looking for a way to computationally output query results based on a query whose column names you do not know, such as…

<cfquery name="queryName" ...>
    select * from product
</cfquery>

…then you can use the queryName.ColumnList variable, which returns a comma separated list of all column names. You could subsequently iterate over this list, and output as required.

For example, to get a simple HTML table output:

<table border=1>
    <cfloop from="0" to="#queryName.RecordCount#" index="row">
        <cfif row eq 0>
            <tr>
                <cfloop list="#queryName.ColumnList#" index="column" delimiters=",">
                    <th><cfoutput>#column#</cfoutput></th>  
                </cfloop>
            </tr>
        <cfelse>
            <tr>
                <cfloop list="#queryName.ColumnList#" index="column" delimiters=",">
                    <td><cfoutput>#queryName[column][row]#</cfoutput></td>
                </cfloop>
            </tr>
    </cfif>
    </cfloop>
</table>

Apologies if this isn’t what you meant!
