Question

I have a .cfc on my server that I use to run a query and send the result back to a phonegap app. I cannot get the syntax right to check if any data has been returned in a query and send back a string in the result like “no data found” to display. here’s my code…

remote array function getintList() {
        var q = new com.adobe.coldfusion.query();
        q.setDatasource("myData");
        q.setSQL("select id1, Date, ShowLInk, IntName, description from myData Where intyear = #dateformat(Now(), "YYYY")# order by date desc");
        var data = q.execute().getResult();
        var result = [];
        for(var i=1; i<= data.recordCount; i++) {
            arrayAppend(result, {"id"=data.id1[i], "name"=data.IntName[i], "date"=dateformat(data.date[i], "mmmm d, yyyy"), "description"=data.description[i], "showlink"=data.ShowLInk[i]});
        }
        return result;
    }

Thought maybe I could do a cfif statement like this but it doesn’t work…

<cfif data.recordcount lt 1>
result = "no data"
return result;
<cfelse>
return result;
</cfif>

Hope someone can help me.

Well results is an array.

If your in phone gap I assume then javascript is handling the result then simply use javascript length on the result.

ie

if(result.length){
    //have data doStuff
}else{
    //noData
}
