MySQL new plugins

Hello I've compiled an old GM with new MySQL updates and I got mysql_ping and mysql_query error.

I've read another post's that users posted about the same problem but I still don't know how to fix it because I'm newbie on Pawno and MySQL.

pawn Code:

new comandoquery[512];





format(comandoquery, sizeof(comandoquery), "UPDATE accounts SET HP='%f' WHERE Name='%s'",PlayerInfo[playerid][pHP],PlayerName(playerid));

Can someone help me please?
