i am working on a way to get info from a database , when i get .type and .attributes it returns numbers , does anybody have a documentation of what they all mean? i got these types up to now

2 Integer
3 Long integer
4 Single
5 double
6 currency
7 Data/time
11 Boolean
17 Byte
72 Replicant id
131 Decimal
202 Text
203 Memo / Hyperlink
205 Ole object

but i have no ideas what the attributes are nor what it returns really.

so how to check if a item is a PRIMARY KEY , or an autoincrement etc etc...
