Make any column autoGenerate (Not Primary Key) in Room Persistence Library

I want to auto generate

ID // auto but not primary

Column and set

productID // primary not auto

as the primary key... Is it possible or my idea is wrong...? if my idea is wrong then please give me the write info... thanks

//@PrimaryKey(autoGenerate = true)
@Nullable  // I want to autogenerate this "ID" column 
private long ID;

@ColumnInfo(name = "pCategorySubID")
@SerializedName("pCategorySubID")
@Expose
private String pCategorySubID;

@PrimaryKey // this is my primary key
@ColumnInfo(name = "ProductID")
@SerializedName("ProductID")
@Expose
@NonNull
private String productID;
