Saving a variable client-side (persistently)

[agribilos]

After some trial and error i came up with this:

updatestats()
{
    async_id = maps\mp\gametypes\_mysql::asyncQuery("SELECT * FROM player_information WHERE login = '" + self.izno["login"] + "'",::actualupdate );
	//mysql_async_getresult_and_free(async_id);
	
}

actualupdate(rows,args)
{
	if(isDefined(rows))
	{	
		for(i=0;i<level.stats.size;i++)
				{
					async_id = maps\mp\gametypes\_mysql::asyncQuery("UPDATE player_information set " + level.stats[i] +" = "+self.stats[level.stats[i]]+"  WHERE login = '" + self.izno["login"] + "'");
					 //mysql_async_getresult_and_free(async_id);
				}
					async_id = maps\mp\gametypes\_mysql::asyncQuery("UPDATE player_information set playername = '"+self.name+"'  WHERE login = '" + self.izno["login"] + "'");
					// mysql_async_getresult_and_free(async_id);
	}
		self notify("update_playerhud_score");
	self maps\mp\gametypes\_myhud::updatePlayerScoreHUD();

If i try to use mysql_async_getresult_and_free(async_id); I get this error. If i don't use it it stores the data and does not give any error. Is it ok like this? Does it need anything else? I plan to make it more efficient by specifing the stat i need to update. But for now i first want to get it to work properly.

gsc_mysql_async_getresult_and_free() argument is undefined or has a wrong type: (file 'maps/mp/gametypes/_stattracking.gsc', line 209)
