A little tip

This morning I needed to modify TODBCConnection in the unit
odbcconn.pas. The problem was that it didn't know a field type (BLOB)
retrieved from an IBM DB2 database. I simply added that when a field
type is unknown it must be considered as BLOB and this trick worked
well. To use this feature, I had to rebuild fpc. What about add a
boolean property that lets us choose if an unknown field type must be
equivalent to a blob field?

I don't think such a property would be satisfying.
The better alternative here would be a OnUnknownFieldType-Handler with
a FieldType (as var) and Fieldname, and maybe some other infos.
So the programmer can choose what to do, and when.
