PreserveSingleQuote Gotcha

After scratching my head for a while wondering why the below code;#preservesinglequotes(myArray[1])#was returning the error. Invalid CFML construct found on line 8 at column 26.
ColdFusion was looking at the following text:
[I was sure that the array held a query then have just found out that preserveSingleQuotes only excepts simple values. So the above code should look more like#preservesinglequotes(sqlQry)#You would think that surely this could be error trapped by the CF server to inform you that you can only pass in simple values?
