If it's only single parameter

pawn Код:

stock MySQL_SaveCharacterStat(playerid, field[], E_CHARACTER_INFO:stat, format)
{
    switch(format)
    {
        case 'i', 'd': printf("%d", gCharacterInfo[playerid][stat]);
        case 'f': printf("%f", gCharacterInfo[playerid][stat]);
        case 's': printf("%s", gCharacterInfo[playerid][stat]);
    }
}

And you pass the parameter with single quotes.
