Hi,

If I include a SUM operator in one of my php files (want to group by code and the get the total price per code), I will get an error:

...
// customise the SQL SELECT statement
$sql_select = 'code, SUM(price)';
$sql_from = null;
$sql_where = null;
$sql_groupby = 'code';
$sql_having = null;
$sql_orderby = null;
$sql_search_table = null;
...

here is the error:

Fatal Error: Uncaught exception fron DOMException, message = Invalid Character Error (# 256).

Error in line 385 of file 'C:\xampp\htdocs\radicore\includes\error.inc'.

Thanks.
Dan

You must provide an alias name using 'SUM(price) AS alias' otherwise when it comes to write that column name into the XML document it will barf as 'SUM(price)' contains '(' and ')' which are invalid as element names in XML.
