Thanks Aegis !
I think it is the best way to execute queries result. and it's working !
I advice developpers to add the evaluation expression if they are assigning database content to a variable. Otherwise coldfusion will only execute the code but won't evaluate variables.
i.e
<cfset myContent = "">
<cfloop query = "myQuery">
<cfset myContent = myContent & #evaluate( de( '#content_fre#' ) )# & " ">
</cfloop>
Thanks again ..
