Dynamically checking off checkboxes

Question

Hi,
I have a simple form with some checkboxes.  The user checks them off and the values get store in a db.
I like to eat:
Form page:
  <input type="Checkbox" name="fruit" value="apples">apples ....
- apples
- oranges
- bananas
- grapes
So on the edit page if the user has checked off all, but oranges it should be displayed from the db like so:
x apples
- oranges
x bananas
x grapes
I started by doing this, but it doesn't quit cut it.  Maybe merging the values of the form fields and the db fields into one list would work?
<cfoutput query="getinfo">
         <cfif fruit EQ '#fruit#'>
         <input type="Checkbox" name="fruit" value="#fruit#" checked>x apples
         <cfelse>
         <input type="Checkbox" name="fruit" value="#fruit#" >apples
</cfoutput>
Any ideas would be much appreciated!

Database table: fruitChoice
userID apple orange banana grape
x147d
1

Query to fetch data from the database:
<cfquery name="getInfo" datasource="myDSN">
select apple,orange,banana,grape
from fruitChoice
where userID = '#session.userID#'
</cfquery>
Query to insert data into the database:
<!--- I use the submit field, not a checkbox, to verify whether the form has been submitted. If you don't check a checkbox, x, then the variable form.x wont exist when the form is submitted --->
<cfif isDefined("form.sbmt")>
<cfset isAppleChosen=0>
<cfset isOrangeChosen=0>
<cfset isBananaChosen=0>
<cfset isGrapeChosen=0>
<cfif isDefined("form.apples")>
    <cfset isAppleChosen=1>
</cfif>
<cfif isDefined("form.oranges")>
    <cfset isOrangeChosen=1>
</cfif>
<cfif isDefined("form.bananas")>
    <cfset isBananaChosen=1>
</cfif>
<cfif isDefined("form.grapes")>
    <cfset isGrapeChosen=1>
</cfif>
<cfquery name="saveInfo" datasource="myDSN">
insert into fruitChoice (userID,apple,orange,banana,grape)
values ('#session.userID#',#isAppleChosen#,#isOrangeChosen#,#isBananaChosen#,#isGrapeChosen#)
</cfquery>
</cfif>
And, finally, the form
<form>
    <p>
    <cfif getinfo.apple EQ 1>
        <input type="Checkbox" name="apples" checked>apples
    <cfelse>
        <input type="Checkbox" name="apples">apples
    </cfif>
    </p>
    <p>
    <cfif getinfo.orange EQ 1>
        <input type="Checkbox" name="oranges" checked>oranges
    <cfelse>
        <input type="Checkbox" name="oranges">oranges
    </cfif>
    </p>
    <p>
    <cfif getinfo.banana EQ 1>
        <input type="Checkbox" name="bananas" checked>bananas
    <cfelse>
        <input type="Checkbox" name="bananas">bananas
    </cfif>
    </p>
    <p>
    <cfif getinfo.grape EQ 1>
        <input type="Checkbox" name="grapes" checked>grapes
    <cfelse>
        <input type="Checkbox" name="grapes">grapes
    </cfif>
    </p>
    <p>
    <input type="submit" name="sbmt" value="send">
    </p>
</form>
