Now I'm using the query below in hive to split a row into multiple rows, but I also want to group a "Product" column based on "Category" column each group will match by the order of the group and have ";" to sperate each group and have "," separate item in the group.
SELECT id, customer, prodcut_split
FROM orders lateral view explode(split(product,';')) products AS prodcut_split
Here is my data look like now
| id | Customer| Category | Product |
+----+----------+---------------------------+-----------------------------------+
| 1 | John | Furniture; Technology | Bookcases, Chairs; Phones, Laptop |
| 2 | Bob | Office supplies; Furniture| Paper, Blinders; Tables |
| 3 | Dylan | Furniture | Tables, Chairs, Bookcases |
my desired result will look like:
| id | Customer| Category | Product |
+----+----------+----------------+-----------+
| 1 | John | Furniture | Bookcases |
| 1 | John | Furniture | Chairs |
| 1 | John | Technology | Phones |
| 1 | John | Technology | Laptop |
| 2 | Bob | Office supplies| Paper |
| 2 | Bob | Office supplies| Blinders |
| 2 | Bob | Furniture | Tables |
| 3 | Dylan | Furniture | Tables |
| 3 | Dylan | Furniture | Chairs |
| 3 | Dylan | Furniture | Bookcases |
