Which operation is NOT permitted on tables containing VECTOR columns?

ASELECT

BUPDATE

CDELETE

DJOIN ON VECTOR columns

Show Suggested Answer

Suggested Answer: D

In Oracle 23ai, tables with VECTOR columns support standard DML operations: SELECT (A) retrieves data, UPDATE (B) modifies rows, and DELETE (C) removes rows. However, JOIN ON VECTOR columns (D) is not permitted because VECTOR isn't a relational type for equality comparison; it's for similarity search (e.g., via VECTOR_DISTANCE). Joins must use non-VECTOR columns. Oracle's SQL reference restricts VECTOR to specific operations, excluding direct joins.

I'm gonna go with D) JOIN ON VECTOR columns. Seems like the kind of thing that would get you in trouble if you're not careful.

Haha, D) JOIN ON VECTOR columns, sounds like a recipe for a headache. I wonder if the developers were feeling particularly mischievous when they came up with that one.

Ooh, JOIN ON VECTOR columns, that's a good one. Gotta be careful with those pesky vector columns, am I right?

I'm not sure about this, but I think A) SELECT is also not permitted on tables containing VECTOR columns.

I agree with Rosalia, because JOIN operation is not permitted on tables containing VECTOR columns.
