Escape SQL, doesn't put anything into SQL, it just enables us, to use Special Characters in our SQL Strings. What your looking for is:  query_sql"SELECT Blah blah blah",@var;
 
Special Characters: Anything not a Letter or a Number.

Umm, this is quite an easy script, you should read the scripting manual, to further your knowledge.
prontera,180,150,4 script NPC NAME 123,{ mes "Do stuff here."; mes "I'm the one that gets hidden, and what not."; close; } - script npc_disabler -1,{ OnFri0000: enablenpc "Above NPC Name"; end; OnSat0000: OnInit: disablenpc "Above NPC NAME"; end; }

Here you go.
prontera,180,150,4 script Countdown -1,{ set .name$,strcharinfo(0); set .acctid,getcharid(3); initnpctimer; end; OnTimer20000: mapannounce strnpcinfo(4),"The winner is: "+ .name$ +"",0; stopnpctimer; end; }

OnPCLogin: iLoop: sleep2 3600000; set @playhour,@playhour+1; dispbottom "You have been playing for "+ @playhour +" hour(s)"; goto iLoop; end;
There, that should do what you want... its been nearly 4years since i've been active in the scripting community, but I'm starting to come back, bigger and harder than ever, with the release of several advanced scripts, never before seen. So until then, I appologize if its bugged...
Basically, when a player logs on, it will do nothing for exactly 1 hour, after that, it will announce to the player only, that they have been on for X amount of hours, and will repeat the proccess every hour.
