Code:

format(string2, sizeof(string2), "%s", mysql_store_result());

What Wicko posted and that ^ is the problem. You're trying to get a string from mysql_store_result ?

Try this:

Code:

mysql_log(1);
	mysql_connect("", "", "", "", 0);
 	new string[256], data[256];
 	format(string, sizeof(string), "SELECT `user_pass` FROM `map_users` WHERE `user_nick`='%s'", PN(playerid));
 	mysql_query(string);
 	mysql_store_result();
 	if(mysql_fetch_field("user_pass", data))
 	{
	  SendClientMessage(playerid, ZOLTY, data);
 	}
 	else
 	{
 	  SendClientMessage(playerid, ZOLTY, "B");
 	}
