This assumes that the value of Recordset1.name is  http://www.google.com

<p>thanks for your time!  I tried to manipulate that code into what i have and it's throwing internal server error.  I'd like the name field to be the active link from the url they type in.    heres what i have for my output code.

<cfoutput query="Recordset1">

    <tr>

      <td>#Recordset1.breed# </td>

      <td>#Recordset1.name#</td>

      <td>#Recordset1.bred# </td>

     <td>#Recordset1.due# </td>

    </tr></p>

Since you want a link, I expected something like

<td><a href="#Recordset1.name#" title="Some title">Some name</a></td>

In any case, the internal server error suggests something else is playing up. Could you show us your query.

One immediate remark: a CLOB with a maxLength of 50? I would use cf_sql_varchar in place of cf_sql_clob. Unless of course you have a good reason to use CLOB type. For example, are the columns of the table litters of type CLOB?

Also, use the null attribute of the cfqueryparam tag. It is False by default. However, if you set it to True, the query will ignore the value attribute and insert Null into the database table. Something like this

<cfset isBreedNull = true>

<cfset isNameNull = true>

<cfset isBredNull = true>

<cfset isDueNull = true>

<cfif IsDefined("FORM.breed") AND FORM.breed NEQ "">

    <cfset isBreedNull = false>

</cfif>

<cfif IsDefined("FORM.name") AND FORM.name NEQ "">

    <cfset isNameNull = false>

</cfif>

<cfif IsDefined("FORM.bred") AND FORM.bred NEQ "">

    <cfset isBredNull = false>

</cfif>

<cfif IsDefined("FORM.due") AND FORM.due NEQ "">

    <cfset isDueNull = false>

</cfif>

INSERT INTO litters (breed, name, bred, due)

VALUES (

        <cfqueryparam value="#FORM.breed#" cfsqltype="cf_sql_varchar" maxlength="50" null="#isBreedNull#">

        ,<cfqueryparam value="#FORM.name#" cfsqltype="cf_sql_varchar" maxlength="50" null="#isNameNull#">

        ,<cfqueryparam value="#FORM.bred#" cfsqltype="cf_sql_varchar" maxlength="50" null="#isBredNull#">

        ,<cfqueryparam value="#FORM.due#" cfsqltype="cf_sql_varchar" maxlength="50" null="#isDueNull#">

)
