Hello,
[Quoted] How would I go about building a header table that would have the following:
I have a large table with these columns:
PR_KEY, ID_NUM, PHONE_NUM, CONTACT_DATE
This header table should have a unique primary key that points to
another table
It should also have a CONTACT_DATE field that, and a time stamp field.
Now this primary key from header table will correspond with another table - that other table contains a PK field (that matches the Primary Key of the header table) and two foreign keys (namely the ID_NUM, & PHONE_NUM) - the ID_NUM, & PHONE_NUM should be indexed.
The header table will contain a list of distinctive CONTACT_DATEs from the larger table. So when I ask for all CONTACT_DATEs = 28-MAY-2001 it will go to the other table and quickly pull all the records from the Large Table.
Is there anything specific I would need to do to the Large table?
Basically what I am trying to do here is differentiate the records of the large table based upon the CONTACT_DATE.
Confused? I am.
Any ideas?
