I want add new table Products into current DB. I have performed the following steps: Step 1: Change files AndroidManifest.xml ``` <meta-data android:name="AA_DB_VERSION" android:value="2" /> ``` Step 2: Create new file **2.sql** in folder _assets/migrations_ ``` DROP TABLE IF EXISTS "Products"; CREATE TABLE IF NOT EXISTS "Products" ("Id" INTEGER,"p_name" TEXT,"p_des" TEXT,"p_price" TEXT); ``` Step 3: Create new file Products.java ``` @Table(name = "Products") public class Products extends Model implements Serializable { @Column(name = "Id") public Integer Id; @Column(name = "p_name") public String p_name; @Column(name = "p_des") public String p_des; @Column(name = "p_price") public String p_price; public Products() { super(); } } ``` When I update the version app, I get the following error: `SQLiteLog: (1) duplicate column name: Id in "CREATE TABLE IF NOT EXISTS Products (Id INTEGER PRIMARY KEY AUTOINCREMENT, Id INTEGER PRIMARY KEY AUTOINCREMENT, p_name TEXT, p_des TEXT, p_price TEXT);"`
