Mysql Error :
[18:17:16] [ERROR] "mysql_tquery" - invalid connection handle (ID = 0)
[18:17:18] [ERROR] CMySQLConnection::Connect - (error #1045) Access denied for user 'samp' localhost (using password: YES)
[18:17:18] [ERROR] CMySQLConnection::Connect - (error #1045) Access denied for user 'samp' localhost (using password: YES)
[18:17:20] [WARNING] CMySQLHandle::Create - connection already exists
[18:17:20] [ERROR] CMySQLConnection::Connect - (error #1045) Access denied for user 'samp' localhost (using password: YES)
[18:17:20] [ERROR] CMySQLConnection::Connect - (error #1045) Access denied for user 'samp' localhost (using password: YES)

OnPlayerConnect :

{
new nachricht[128];
format(nachricht,sizeof(nachricht),"Du bist mit der ID %i verbunden.",playerid);
SendClientMessage(playerid,COLOR_RED,nachricht);

//Login/Register
new name[MAX_PLAYER_NAME],query[128];
GetPlayerName(playerid,name,sizeof(name));
format(query,sizeof(query),"SELECT id FROM user WHERE username='%s'",name);
mysql_function_query(dbhandle,query,true,"OnUserCheck","i",playerid);
return 1;
}

das hier ist das

//MySQL
#define db_host "127.0.0.1"
#define db_user "samp"
#define db_pass "**HUST***"
#define db_db "samp"

//MySQL
#define db_host "localhost"
#define db_user "root"
#define db_pass ""
#define db_db "samp_db"
Richtig so?

Jetzt hab ich diesen error

[20:42:49] [ERROR] "mysql_tquery" - invalid connection handle (ID = 0)
