問題文
A development team wants to store the output of an embedding model next to the business rows of the same table. Which statement about the vector data type is correct?
選択肢
- It holds the embedding as a column of the same table and the number of dimensions along with the dimension format can be declared or left wide open.
- It holds the embedding as a character string in a column and the search later parses that string into numbers for every comparison it performs.
- It holds the embedding as a large object and the number of dimensions is then derived from the length of that object at query time.
- It holds the embedding inside a separate store outside the database and the table then keeps a reference which the search resolves at query time.
