proc format?

deleted_user — Fri, 16 Jul 2010 20:39:35 GMT

HI I have two tables. wonder if i can use proc format or any other SAS programming to achieve the following:

Table #1
Effective Date Rate
20100601 2.5
20090525 2.25
20090302 2.0

Table #2 (has 10,000 records)
Customer LendingDate
A 20090701
B 20090701
..

Basically what i want to do is use the rate Table #1 as reference table to add new column "rate" to customer Table #2. For example
If customer's lending date is 20100622 , then the rate will be 2.5
If customer's lending date is 20100401 , then the rate will be 2.0

My challenge is the table #1 could be growing and I will not be the one update the table. How can i get it done ?

A PROC FORMAT (possibly using CNTLIN= to load from a SAS file) is a reasonable and efficient approach for known, discrete (or range-defined) value mapping (START-END to LABEL using SAS PROC FORMAT terms).

You mention about how can I get it done - presuming you mean to define the association data values, you can load from a SAS member which can be created from external source. Presumption is that someone, somewhere knows what's supposed to be used for this process, correct?
