Bug with preserveSingleQuotes()

OR is it just some really strange 'feature'.

IS it just me or should not both of these work?

WORKING CODE

<cfset reports = [
     {name="Reneawal Date before Issue Date",sql="RenewDate < IssueDate"},
     {name="Expiration Date before Renewal Date",sql="ExpirationDate < RenewDate"},
     {name="Expiration Date before Issue Date",sql="ExpirationDate < IssueDate"},
     {name="Not Fly Anomolies",sql=""},
     {name="Expiration Date NOT December 31st",sql="DAY(ExpirationDate) != 31 OR MONTH(ExpirationDate) != 12"}
     ]>
<cfset variables.sql = reports[1].sql>
<cfquery ...>
    SELECT aField, bField, cField
    FROM aTable
    WHERE #preserveSingleQuotes(variables.sql)#
</cfquery>

FAILING CODE

<cfset reports = [
     {name="Reneawal Date before Issue Date",sql="RenewDate < IssueDate"},
     {name="Expiration Date before Renewal Date",sql="ExpirationDate < RenewDate"},
     {name="Expiration Date before Issue Date",sql="ExpirationDate < IssueDate"},
     {name="Not Fly Anomolies",sql=""},
     {name="Expiration Date NOT December 31st",sql="DAY(ExpirationDate) != 31 OR MONTH(ExpirationDate) != 12"}
     ]>
<cfquery ...>
    SELECT aField, bField, cField
    FROM aTable
    WHERE #preserveSingleQuotes(reports[1].sql)#
</cfquery>

Complex constructs are not supported with function preserveSingleQuotes Use simple variable instead
