-Calculates the distance between two vectors using a specified distance metric. Vector distance is always exact and doesn't use any vector index, even if available. In order to use a vector index and thus perform an approximate vector search, you must use the [VECTOR_SEARCH](vector-search-transact-sql.md) function. To learn more about how vector indexing and vector search works, and the differences between exact and approximate search, refer to [Vectors in the SQL Database Engine](../../relational-databases/vectors/vectors-sql-server.md).
