mysql module new problem in 0.1.0

[Osmith]

I do not quite understand what the problem is.

local query = mysql_query(Server_handler, "SELECT * FROM `player_cred` WHERE `player_name` = '"+getPlayerName(pid)+"' ");
local row = mysql_fetch_assoc(query);
print(row["id"]);
print(row["enter"]);
print(row["pass"]);
