Have you tried the <!--#else--> block of the <!--#in--> tag?

Like so:

<!--#in dBcall-->
   <!--#if "newName == name"-->
    <!--#call "REQUEST.set('titleTrue', 'true')"-->
   <!--#else-->
    <!--#call "REQUEST.set('titleTrue', 'false')"-->
   <!--#/if-->
<!--#else-->
Sorry, no results from the query.
<!--#/in-->
