Query of Queries variable scoping

Question

Is it possible to scope variables when using query of queries? This works

return queryExecute("
        SELECT Title, Slug, Menu, MenuOrder
        FROM qryResult
        WHERE Menu = 'Y'
        ORDER BY MenuOrder
        ",
        [],
        {dbtype = "query"}
        );

This does not work. It throws an error

return queryExecute("
        SELECT Title, Slug, Menu, MenuOrder
        FROM local.qryResult
        WHERE Menu = 'Y'
        ORDER BY MenuOrder
        ",
        [],
        {dbtype = "query"}
        );

What does the 2nd sample do that constitutes, "does not"? – Dan Bracuk Nov 04 '15 at 04:07 — Dan Bracuk, Nov 04 '15 at 04:07
Try wrapping `local` within square brackets. – Abhishekh Gupta Nov 04 '15 at 04:38 — Abhishekh Gupta, Nov 04 '15 at 04:38
`[local].qryResult` works! – James A Mohler Nov 04 '15 at 04:54 — James A Mohler, Nov 04 '15 at 04:54

LOCAL is a reserved word in ColdFusion Query of Query and SQL.

So, wrap LOCAL with square brackets[] like this:

return queryExecute("
        SELECT Title, Slug, Menu, MenuOrder
        FROM [local].qryResult
        WHERE Menu = 'Y'
        ORDER BY MenuOrder
        ",
        [],
        {dbtype = "query"}
        );

OR

Use some other name for function local scope i.e.,

var newLocal = structNew();
newLocal.qryResult = queryNew("");
return queryExecute("
        SELECT Title, Slug, Menu, MenuOrder
        FROM newLocal.qryResult
        WHERE Menu = 'Y'
        ORDER BY MenuOrder
        ",
        [],
        {dbtype = "query"}
        );
