Should sql_result_free() always be called, no matter what the circumstance, in order to discharge memory allocated to query result sets and/or metadata? Or is it not necessary in certain situations, for example when script is broken via 'exit', i.e. sql_query("db", "SELECT ...", "res"); if(! $dbr(res=>rows)) { # Is it necessary to call sql_result_free() here? sl_send_reply("404", "Not Found"); exit; } Are results implicitly freed at the end of route script execution anyway? Are they tied to transaction persistence in any way? Thanks, -- Alex Balashov - Principal Evariste Systems LLC Tel : +1 678-954-0670 Direct : +1 678-954-0671 Web : http://www.evaristesys.com/
