What's the quickest way to find out all the values under an attributes - response (24) by MBSconnection

thanks. Lot of info I don't even know how to make sense, but I got what I needed. 

Column Name Type Nullable Format Max Length Decimal Decimal Fra Indexed? Unique? Primary? Char Type Temporal Column

NA_ID                 I  N -(10)9                         4 null null Y N P null N

M_NBR                I  N -(10)9                         4 null null Y N P null N

T_NBR                 I2 Y -(5)9                         2 null null Y N S null N

NA_ID                I  Y -(10)9                         4 null null Y N S null N

What is I2? CV is VARCHAR, I is Integer, What is CF? and What is PM Data Type?

In a  row that has Indexed Y, Unique N and Primary P does that mean this field is a Primary Key Field? and Nulls are not allowed?

In a  row that has Indexed Y, Unique N and Primary S What does that S mean?

Thanks for Help!
