Sqlite教程(3) SQlite Query

Configuration是属於util工具包。

把所有环境设置都定义在Configuration工具包里，那麽这个Configuration就是独立的单一入囗。

在架构上，可以提高耦合度，而且出Bug时也方便追纵。

更重要的是，假如表格的Name需要改变，那只要在Configuration里改一下变量就行，不用担心其他控件会因此出Bug。

这里第一部份定义了SQlite的Query，第二部份定义了okhttp的URL。

1. SQlite的Query

/*
    *   SQLite
     */
    public static final String DB_NAME = "epdz.db";
    public static int DB_VERSION = 23;

    /*
    *   SQLite [Table]User
     */
    public static final String DB_USER = "epdz_user";

            USER_REGISTER_DATE + " VARCHAR(256) NOT NULL );";

    /*
    *   SQlite [Table] Create post
    */
    public static final String CREATE_POST_TABLE = " CREATE TABLE " +DB_POST+ " (" +
            POST_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            POST_POSTID + " VARCHAR(32) NOT NULL, " +

            POST_ISTOP + " VARCHAR(32), " +
            POST_VISITABLE + " VARCHAR(32) );";

2. okhttp的URL

这里只出一部份代码供叁考。
