Question

I have the following table join that runs fine in Microsoft SQL Server and returns the expected results.

SELECT     d.id1, c.content_type
FROM       Document2 AS d INNER JOIN
           Content2 AS c ON d.content_id = c.content_id
WHERE     (d.class_id = 1)

However when I place the statement into a ColdFusion CFC, the statement will not execute and I am not getting anything to return. Does the syntax change within the CFC file? Is the Microsoft SQL syntax different from the ColdFusion CFC syntax? Or am I missing something else here?

This is the relevant function. I can get this code to work if I use a simple SQL statement that is not a table join. However, when I insert the table join statement nothing will return.

  remote array function getcontent() {
    var q = new com.adobe.coldfusion.query();
     q.addParam( name="searchParam", value="#searchName#" );
    q.setDatasource("Document");
    q.setSQL("SELECT d.id1, c.content_type FROM Document2 
    AS d INNER JOIN   
    Content2 AS c ON d.content_id = c.content_id WHERE (d.class_id = 1)");

    var data = q.execute().getResult();
    var result = [];
    for(var i=1; i<= data.recordCount; i++) {
        arrayAppend(result, {"id"=data.d.id1[i], "Type"=data.c.content_type[i]});
    }
    return result;
}

Answer 1

The problem is this line of code:

arrayAppend(result, {"id"=data.d.id1[i], "Type"=data.c.content_type[i]});

You don’t refer to database variables like that – the table alias is not part of the column alias.

You should simply use:

data.id1[i]

If you did actually have a . in the column alias, then you would need to refer to it using bracket notation, like this:

data['d.id1'][i]

But again, the table alias isn’t part of the column alias, so that’s not needed.
