kod

Tak mam napisane to ja (fragment klasy, jedna funkcja):

public static void downloadFromDatabase(String database, String where, String item) { // checking login from database
        try {
            con = DriverManager.getConnection("jdbc:mysql://reykez.pl:3306/reykez_xxxxxx" , "reykez_xxxxxx" , "xxxxxxxx");
            st = con.createStatement();
            rs = st.executeQuery("select * from " + database + " WHERE " + where + " = '" + item + "'"); // select from nickname
        } catch(Exception e) { e.printStackTrace(); }
    }
---------------------------------------------------------------------------------------
Ale ten sam kod można napisać na przykład tak:
public static void downloadFromDatabase(String database, String where, String item)
{
try {
con = DriverManager.getConnection("jdbc:mysql://reykez.pl:3306/reykez_xxxxxx" , "reykez_xxxxxx" , "xxxxxxxx");
st = con.createStatement();
rs = st.executeQuery("select * from " + database + " WHERE " + where + " = '" + item + "'");
}
catch(Exception e)
{
e.printStackTrace();
}
}
