Referential indexes

Hi all


Got this query from a developer, or actually they are actually arguing
with the DBA team.

Table A - master, acc number field              also only column in PK

Table B - Child, acc Number Field               acc number is the first
column in PK, PK contains 2 more columns.

DBA's are saying we don't need a normal non unique stand alone index on
the acc Number field for table B.

Developers want a separate index,
