  How many types of Composite keys we've?

  I know - Composite Primary Key, Composite Foreign Key. Do we have Composite Unique Key also?

  Can we merge 1 column from Primary Key and 1 column from Unique Key?

  Thanks.

  My recommendation is "Try it". You may forget what you've been told but you won't forget what you've done. 😉

  RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
  First step towards the paradigm shift of writing Set Based code:
  ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

  Change is inevitable... Change for the better is not.
