So I have this table of book orders, it contains 2 columns, one is the order ID(primary key) and another is the ID of the book that the customer ordered. For example:

| OrderID | BookID |

| 0001 | B002 |

| 0002 | B005 |

| 0003 | B002 |

| 0004 | B003 |

| 0005 | B005 |

| 0006 | B002 |

| 0007 | B002 |

What I want is to get the IDs of the books that got 2 or more purchases/orders, for example if I run the SQL query against the above data, I would get this as the result:

| BookID |

| B002 |

| B005 |

I don't know if this can be archived in SQL or I have to built a simpler statement and repetitive run the query against all the records in another language. I need some help and thanks for reading my question.
