Hi,

I didn't want to burn a SQL type in the application code. Because if I use 
PostgreSQL a BLOB is named as "oid" in Oracle is "long raw" and other BDMS can
name it diferently.

I am looking for a solution that at runtime connects to the DBMS and find out 
what SQL type corresponds to BLOB and then create a table with a field of 
that type.
