A design question, my RATE table looks something like this....

SQL> desc rate
Name
Null? Type

----------------- RATE_CODE NOT NULL CHAR(2) RATE_EFFECTIVE_START_DATE NOT NULL DATE RATE_EFFECTIVE_END_DATE NOT NULL DATE
.
.

those are the PK fields...and the SQL to query the table is easy. I am trying to determine if I can "tighten up" the table, like this...

SQL> desc rate
Name
Null? Type

----------------- RATE_CODE NOT NULL CHAR(2) RATE_EFFECTIVE_DATE NOT NULL DATE

I just haven't been able to code the right SQL.

Has anyone else taken this approach?

Sorry for these design questions, I am just being very anal about every table, PK column and index, before we dive into development and everything becomes "hard coded".

TIA!!!! Chris
